-## Issues
-  * Include screenshots and animated GIFs whenever possible, they are immensely
-    helpful.
-  * Include the behavior you expected to happen and other places you've seen
-    that behavior such as Emacs, vi, Xcode, etc.
-  * Check the Console app for stack traces to include if reporting a crash.
-  * Check the Dev tools (`alt-cmd-i`) for errors and stack traces to include.
+The following is a set of guidelines for contributing to Atom and its packages,
+which are hosted in the [Atom Organization](https://github.com/atom) on GitHub.
+If you're unsure which package is causing your problem or if you're having an
+issue with Atom core, please open an issue on the [main atom repository](https://github.com/atom/atom/issues).
+These are just guidelines, not rules, use your best judgement and feel free to
+propose changes to this document in a pull request.
+
+## Submitting Issues
+
+* Check the [debugging guide](https://atom.io/docs/latest/debugging) for tips
+  on debugging. You might be able to find the cause of the problem and fix 
+  things yourself.
+* Include the version of Atom you are using and the OS.
+* Include screenshots and animated GIFs whenever possible; they are immensely
+  helpful.
+* Include the behavior you expected and other places you've seen that behavior
+  such as Emacs, vi, Xcode, etc.
+* Check the dev tools (`alt-cmd-i`) for errors to include. If the dev tools 
+  are open _before_ the error is triggered, a full stack trace for the error
+  will be logged. If you can reproduce the error, use this approach to get the
+  full stack trace and include it in the issue.
+* On Mac, check Console.app for stack traces to include if reporting a crash.
+* Perform a cursory search to see if a similar issue has already been submitted.

     * Built in Node Modules (such as `path`)
     * Built in Atom and Atom Shell Modules (such as `atom`, `shell`)
     * Local Modules (using relative paths)
-  * Class variables and methods should be in the following order:
-    * Class methods (methods starting with a `@`)
-    * Instance methods
-  * Beware of platform differences
+* Place class properties in the following order:
+    * Class methods and properties (methods starting with a `@`)
+    * Instance methods and properties
+* Avoid platform-dependent code:
     * Use `require('atom').fs.getHomeDirectory()` to get the home directory.
     * Use `path.join()` to concatenate filenames.
-    * Temporary directory is not `/tmp` on Windows, use `os.tmpdir()` when
-      possible
+    * Use `os.tmpdir()` rather than `/tmp` when you need to reference the
+      temporary directory.
 
 ## Git Commit Messages
-  * Use the present tense
-  * Reference issues and pull requests liberally
-  * Consider starting the commit message with an applicable emoji:
+
+* Use the present tense ("Add feature" not "Added feature")
+* Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
+* Limit the first line to 72 characters or less
+* Reference issues and pull requests liberally
+* Consider starting the commit message with an applicable emoji:
     * :lipstick: `:lipstick:` when improving the format/structure of the code
     * :racehorse: `:racehorse:` when improving performance
     * :non-potable_water: `:non-potable_water:` when plugging memory leaks
     * :memo: `:memo:` when writing docs
     * :penguin: `:penguin:` when fixing something on Linux
+    * :apple: `:apple:` when fixing something on Mac OS
+    * :checkered_flag: `:checkered_flag:` when fixing something on Windows
+    * :bug: `:bug:` when fixing a bug
+    * :fire: `:fire:` when removing code or files
+    * :green_heart: `:green_heart:` when fixing the CI build
+    * :white_check_mark: `:white_check_mark:` when adding tests
+    * :lock: `:lock:` when dealing with security
 
 ## CoffeeScript Styleguide
 
 * Set parameter defaults without spaces around the equal sign
-  * `clear = (count=1) ->` instead of `clear = (count = 1) ->`
+    * `clear = (count=1) ->` instead of `clear = (count = 1) ->`
+* Use parentheses if it improves code clarity.
+* Prefer alphabetic keywords to symbolic keywords:
+    * `a is b` instead of `a == b`
+* Avoid spaces inside the curly-braces of hash literals:
+    * `{a: 1, b: 2}` instead of `{ a: 1, b: 2 }`
+* Include a single line of whitespace between methods.
 
 ## Documentation Styleguide
 
 * Use [TomDoc](http://tomdoc.org).
 * Use [Markdown](https://daringfireball.net/projects/markdown).
-* Reference classes with `{ClassName}`.
-* Reference instance methods with `{ClassName::methodName}`.
-* Reference class methods with `{ClassName.methodName}`.
-* Delegate to comments elsewhere with `{Delegates to: ClassName.methodName}`
-  style notation.
+* Reference methods and classes in markdown with the custom `{}` notation:
+    * Reference classes with `{ClassName}`
+    * Reference instance methods with `{ClassName::methodName}`
+    * Reference class methods with `{ClassName.methodName}`
+    * Delegate to comments elsewhere with `{Delegates to: ClassName.methodName}`
+      style notation.

+## Developing Node Modules
+
+Atom contains a number of packages that are Node modules instead of Atom packages. If you want to
+make changes to the Node modules, for instance `atom-keymap`, you have to link them into the
+development environment differently than you would a normal Atom package.
+
+### Linking a Node Module Into Your Atom Dev Environment
+
+Here are the steps to run a local version of a node module *not an apm* within Atom. We're using
+`atom-keymap` as an example:
+
+```bash
+$ git clone https://github.com/atom/atom-keymap.git
+$ cd atom-keymap
+$ npm install
+$ npm link
+$ apm rebuild # This is the special step, it makes the npm work with Atom's version of Node
+$ cd WHERE-YOU-CLONED-ATOM
+$ npm link atom-keymap
+$ atom # Should work!
+```
+
+After this, you'll have to `npm install` and `apm rebuild` when you make a change to the node
+module's code.

+## Atom.io package and update API
+
+This guide describes the web API used by [apm](https://github.com/atom/apm) and
+Atom. The vast majority of use cases are met by the `apm` command-line tool,
+which does other useful things like incrementing your version in `package.json`
+and making sure you have pushed your git tag. In fact, Atom itself shells out to
+`apm` rather than hitting the API directly. If you're curious about how Atom
+uses `apm`, see the [PackageManager class](https://github.com/atom/settings-view/blob/master/lib/package-manager.coffee)
+in the `settings-view` package.
+
+### Authorization
+
+For calls to the API that require authentication, provide a valid token from your
+[Atom.io account page](https://atom.io/account) in the `Authorization` header.
+
+### Media type
+
+All requests that take parameters require `application/json`.
+
+## Resources

+      }
+    },
+    ...
+  ]
+```
+
+#### GET /api/packages/:package_name
+
+Returns package details and versions for a single package
+
+Parameters:
+
+- **engine** (optional) - Only show packages with versions compatible with this
+  Atom version. Must be valid [SemVer](http://semver.org).
+
+Returns:
+
+```json
+  {
+    "releases": {
+      "latest": "0.6.0"

+    },
+    "versions": [
+      (see single version output below)
+      ...,
+    ]
+  }
+```
+
+#### POST /api/packages
+
+Create a new package; requires authentication.
+
+The name and version will be fetched from the `package.json`
+file in the specified repository. The authenticating user *must* have access
+to the indicated repository.
+
+When a package is created, a release hook is registered with GitHub for package
+version creation.
+
+Parameters:
+
+- **repository** - String. The repository containing the plugin, in the form "owner/repo"
+
+Returns:
+
+- **201** - Successfully created, returns created package.
+- **400** - Repository is inaccessible, nonexistent, not an atom package. Possible
+  error messages include:
+  - That repo does not exist, isn't an atom package, or atombot does not have access
+  - The package.json at owner/repo isn't valid
+- **409** - A package by that name already exists
+
+
+#### DELETE /api/packages/:package_name
+
+Delete a package; requires authentication.
+
+Returns:
+
+- **204** - Success
+- **400** - Repository is inaccessible
+- **401** - Unauthorized
+
+### Package Versions
+
+#### GET /api/packages/:package_name/versions/:version_name
+
+Returns `package.json` with `dist` key added for e.g. tarball download:
+
+```json
+  {
+    "bugs": {
+      "url": "https://github.com/thedaniel/test-package/issues"

+  }
+```
+
+
+### Creating a new package version
+
+#### POST /api/packages/:package_name/versions
+
+Creates a new package version from a git tag; requires authentication.
+
+#### Parameters
+
+- **tag** - A git tag for the version you'd like to create. It's important to note
+  that the version name will not be taken from the tag, but from the `version`
+  key in the `package.json` file at that ref. The authenticating user *must* have
+  access to the package repository.
+
+#### Returns
+
+- **201** - Successfully created. Returns created version.

+- **409** - Version exists
+
+### Delete a version
+
+#### DELETE /api/packages/:package_name/versions/:version_name
+
+Deletes a package version; requires authentication.
+
+Note that a version cannot be republished with a different tag if it is deleted.
+If you need to delete the latest version of a package for e.g. security reasons,
+you'll need to increment the version when republishing.
+
+Returns 204 No Content
+
+
+### Stars
+
+#### GET /api/users/:login/stars
+

+## Instructions
+
+  ```sh
+  git clone https://github.com/atom/atom
+  cd atom
+  script/build # Creates application at $TMPDIR/atom-build/Atom
+  sudo script/grunt install # Installs command to /usr/local/bin/atom
+  script/grunt mkdeb # Generates a .deb package at $TMPDIR/atom-build
+  ```
+
+## Troubleshooting
+
+
+### Exception: "TypeError: Unable to watch path"
+
+If you get following error with a big traceback right after Atom starts:
+
+  ```
+  TypeError: Unable to watch path
+  ```
+
+you have to increase number of watched files by inotify.  For testing if
+this is the reason for this error you can issue
+
+  ```sh
+  sudo sysctl fs.inotify.max_user_watches=32768
+  ```
+
+and restart Atom.  If Atom now works fine, you can make this setting permanent:
+
+  ```sh
+  echo 32768 > /proc/sys/fs/inotify/max_user_watches
+  ```
+
+See also https://github.com/atom/atom/issues/2082.
+
+### /usr/bin/env: node: No such file or directory
+
+If you get this notice when attempting to `script/build`, you either do not
+have nodejs installed, or node isn't identified as nodejs on your machine.
+If it's the latter, entering `sudo ln -s /usr/bin/nodejs /usr/bin/node` into
+your terminal may fix the issue.

+  cd C:\
+  git clone https://github.com/atom/atom/
+  cd atom
+  script/build # Creates application in the `Program Files` directory
+  ```
+
+## Why do I have to use GitHub for Windows?
+
+You don't, You can use your existing Git! GitHub for Windows's Git Shell is just
+easier to set up. You need to have Posix tools in your `%PATH%` (i.e. `grep`,
+`sed`, et al.), which isn't the default configuration when you install Git. To
+fix this, you probably need to fiddle with your system PATH.
+
+## Troubleshooting
+
+### Common Errors
+* `node is not recognized`
+
+  * If you just installed node you need to restart your computer before node is
+  available on your Path.
+
+
+* `script/build` outputs only the Node and Python versions before returning
+
+  * Try moving the repository to `C:\atom`. Most likely, the path is too long.
+    See [issue #2200](https://github.com/atom/atom/issues/2200).
+
+* `error MSB4025: The project file could not be loaded. Invalid character in the given encoding.`
+
+  * These can occur because your home directory (`%USERPROFILE%`) has non-ASCII
+    characters in it. This is a bug in [gyp](https://code.google.com/p/gyp/)
+    which is used to build native node modules and there is no known workaround.

+# Contributing to Official Atom Packages
+
+If you think you know which package is causing the issue you are reporting, feel
+free to open up the issue in that specific repository instead. When in doubt
+just open the issue here but be aware that it may get closed here and reopened
+in the proper package's repository.
+
+## Hacking on Packages
+
+### Cloning
+
+The first step is creating your own clone. You can of course do this manually
+with git, or you can use the `apm develop` command to create a clone based on
+the package's `repository` field in the `package.json`.
+
+For example, if you want to make changes to the `tree-view` package, run the
+following command:
+
+```
+> apm develop tree-view
+Cloning https://github.com/atom/tree-view ✓
+Installing modules ✓
+~/.atom/dev/packages/tree-view -> ~/github/tree-view
+```
+
+This clones the `tree-view` repository to `~/github`. If you prefer a different
+path, specify it via the `ATOM_REPOS_HOME` environment variable.
+
+### Running in Development Mode
+
+Editing a package in Atom is a bit of a circular experience: you're using Atom
+to modify itself. What happens if you temporarily break something? You don't
+want the version of Atom you're using to edit to become useless in the process.
+For this reason, you'll only want to load packages in **development mode** while
+you are working on them. You'll perform your editing in **stable mode**, only
+switching to development mode to test your changes.
+
+To open a development mode window, use the "Application: Open Dev" command,
+which is normally bound to `cmd-shift-o`. You can also run dev mode from the
+command line with `atom --dev`.
+
+To load your package in development mode, create a symlink to it in
+`~/.atom/dev/packages`. This occurs automatically when you clone the package
+with `apm develop`. You can also run `apm link --dev` and `apm unlink --dev`
+from the package directory to create and remove dev-mode symlinks.
+
+### Installing Dependencies
+
+Finally, you need to install the cloned package's dependencies by running
+`apm install` within the package directory. This step is also performed
+automatically the first time you run `apm develop`, but you'll want to keep
+dependencies up to date by running `apm update` after pulling upstream changes.

-# Contributing to Atom Packages
-
-The following is a set of guidelines for contributing to Atom packages, which
-are hosted in the [Atom Organization](https://github.com/atom) on GitHub. If
-you're unsure which package is causing your problem or if you're having an issue
-with Atom core, please use the feedback form in the application or email
-[atom@github.com](mailto:atom@github.com).
-
-## Submitting Issues
-
-* Include screenshots and animated GIFs whenever possible; they are immensely
-  helpful.
-* Include the behavior you expected and other places you've seen that behavior
-  such as Emacs, vi, Xcode, etc.
-* Check the dev tools (`alt-cmd-i`) for errors and stack traces to include.
-* Check Console.app for stack traces to include if reporting a crash.
-* Perform a cursory search to see if a similar issue has already been submitted.

-## Submitting Pull Requests
-
-### Code Guidelines
-
-* Include screenshots and animated GIFs in your pull request whenever possible.
-* Follow the [CoffeeScript](#coffeescript-styleguide),
-  [JavaScript](https://github.com/styleguide/javascript),
-  and [CSS](https://github.com/styleguide/css) styleguides.
-* Include thoughtfully-worded, well-structured
-  [Jasmine](http://pivotal.github.com/jasmine) specs.
-* Document new code based on the
-  [Documentation Styleguide](#documentation-styleguide)
-* End files with a newline.
-* Place requires in the following order:
-  * Built in Node Modules (such as `path`)
-  * Built in Atom and Atom Shell Modules (such as `atom`, `shell`)
-  * Local Modules (using relative paths)
-* Place class properties in the following order:
-  * Class methods and properties (methods starting with a `@`)
-  * Instance methods and properties
-* Avoid platform-dependent code:
-  * Use `require('atom').fs.getHomeDirectory()` to get the home directory.
-  * Use `path.join()` to concatenate filenames.
-  * Use `os.tmpdir()` rather than `/tmp` when you need to reference the
-    temporary directory.
-
-### Commit Message Guidelines
-  * Use the present tense ("Add feature" not "Added feature")
-  * Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
-  * Limit the first line to 72 characters or less
-  * Reference issues and pull requests liberally
-  * Consider starting the commit message with an applicable emoji:
-    * :lipstick: when improving the format/structure of the code
-    * :racehorse: when improving performance
-    * :non-potable_water: when plugging memory leaks
-    * :memo: when writing docs
-    * :bulb: Check out the [Emoji Cheat Sheet](http://www.emoji-cheat-sheet.com)
-      for more ideas.
-
-## CoffeeScript Styleguide
-
-* Use parentheses if it improves code clarity.
-* Prefer alphabetic keywords to symbolic keywords:
-  * `a is b` instead of `a == b`
-* Avoid spaces inside the curly-braces of hash literals:
-  * `{a: 1, b: 2}` instead of `{ a: 1, b: 2 }`
-* Set parameter defaults without spaces around the equal sign:
-  * `clear = (count=1) ->` instead of `clear = (count = 1) ->`
-* Include a single line of whitespace between methods.
-
-## Documentation Styleguide
-
-* Use [TomDoc](http://tomdoc.org).
-* Use [Markdown](https://daringfireball.net/projects/markdown).
-* Reference methods and classes in markdown with the custom `{}` notation:
-  * Reference classes with `{ClassName}`
-  * Reference instance methods with `{ClassName::methodName}`
-  * Reference class methods with `{ClassName.methodName}`
-
-### Example
-
-```coffee
-# Public: Disable the package with the given name.
-#
-# This method emits multiple events:
-#
-# * `package-will-be-disabled` - before the package is disabled.
-# * `package-disabled`         - after the package is disabled.
-#
-# name     - The {String} name of the package to disable.
-# options  - The {Object} with disable options (default: {}):
-#   :trackTime - `true` to track the amount of time disabling took.
-#   :ignoreErrors - `true` to catch and ignore errors thrown.
-# callback - The {Function} to call after the package has been disabled.
-#
-# Returns `undefined`.
-disablePackage: (name, options, callback) ->

+# Debugging
+
+Atom provides several tools to help you understand unexpected behavior and debug problems. This guide describes some of those tools and a few approaches to help you debug and provide more helpful information when [submitting issues]:
+
+* [Update to the latest version](#update-to-the-latest-version)
+* [Check Atom and package settings](#check-atom-and-package-settings) 
+* [Check the keybindings](#check-the-keybindings)
+* [Check if the problem shows up in safe mode](#check-if-the-problem-shows-up-in-safe-mode)
+* [Check your config files](#check-your-config-files)
+* [Check for errors in the developer tools](#check-for-errors-in-the-developer-tools)
+
+## Update to the latest version
+
+You might be running into an issue which was already fixed in a more recent version of Atom than the one you're using.
+
+If you're building Atom from source, pull down the latest version of master and [re-build][building atom].
+
+If you're using released version, check which version of Atom you're using:
+
+```shell
+$ atom --version
+0.99.0
+```
+
+Head on over to the [list of releases][atom releases] and see if there's a more recent release. You can update to the most recent release by downloading Atom from the releases page, or with the in-app auto-updater. The in-app auto-updater checks for and downloads a new version after you restart Atom, or if you use the Atom > Check for Update menu option.
+
+## Check Atom and package settings
+
+In some cases, unexpected behavior might be caused by misconfigured or unconfigured settings in Atom or in one of the packages.
+
+Open Atom's Settings View with `cmd-,` or the Atom > Preferences menu option.
+
+![Settings View]
+
+Check Atom's settings in the Settings pane, there's a description of each configuration option [here][customizing guide]. For example, if you want Atom to use hard tabs (real tabs) and not soft tabs (spaces), disable the "Soft Tabs" option.
+
+Since Atom ships with a set of packages and you can install additional packages yourself, check the list of packages and their settings. For example, if you'd like to get rid of the vertical line in the middle of the editor, disable the [Wrap Guide package]. And if you don't like it when Atom strips trailing whitespace or ensures that there's a single trailing newline in the file, you can configure that in the [Whitespace packages'][whitespace package] settings.
+
+![Package Settings]
+
+## Check the keybindings
+
+If a command is not executing when you hit a keystroke or the wrong command is executing, there might be an issue with the keybindings for that keystroke. Atom ships with the [Keybinding resolver][keybinding resolver package], a neat package which helps you understand which keybindings are executed.
+
+Show the keybinding resolver with <code>cmd-.</code> or with "Key Binding Resolver: Show" from the Command palette. With the keybinding resolver shown, hit a keystroke:
+
+![Keybinding Resolver]
+
+The keybinding resolver shows you a list of keybindings that exist for the keystroke, where each item in the list has the following:
+* the command for the keybinding,
+* the CSS selector used to define the context in which the keybinding is valid, and
+* the file in which the keybinding is defined.
+
+Of all the keybinding that are listed (grey color), at most one keybinding is matched and executed (green color). If the command you wanted to trigger isn't listed, then a keybinding for that command hasn't been defined. More keybindings are provided by [packages] and you can [define your own keybindings][customizing keybindings].
+
+If multiple keybindings are matched, Atom determines which keybinding will be executed based on the [specificity of the selectors and the order in which they were loaded][specificity and order]. If the command you wanted to trigger is listed in the Keybinding resolver, but wasn't the one that was executed, this is normally explained by one of two causes:
+* the keystroke was not used in the context defined by the keybinding's selector. For example, you can't trigger the "Tree View: Add File" command if the Tree View is not focused, or
+* there is another keybinding that took precedence. This often happens when you install a package which defines keybinding that conflict with existing keybindings. If the package's keybindings have selectors with higher specificity or were loaded later, they'll have priority over existing ones.
+
+Atom loads core Atom keybindings and package keybindings first, and user-defined keybindings after last. Since user-defined keybindings are loaded last, you can use your `keymap.cson` file to tweak the keybindings and sort out problems like these. For example, you can remove keybindings with [the `unset!` directive][unset directive].
+
+If you notice that a package's keybindings are taking precedence over core Atom keybindings, it might be a good idea to report the issue on the package's GitHub repository.
+
+## Check if the problem shows up in safe mode
+
+A large part of Atom's functionality comes from packages you can install. In some cases, these packages might be causing unexpected behavior, problems, or performance issues.
+
+To determine if a package you installed is causing problems, start Atom from the terminal in safe mode:
+
+```
+$ atom --safe
+```
+
+This starts Atom, but does not load packages from `~/.atom/packages` or `~/.atom/dev/packages`. If you can no longer reproduce the problem in safe mode, it's likely it was caused by one of the packages.
+
+To figure out which package is causing trouble, start Atom normally again and open Settings (`cmd-,`). Since Settings allow you to disable each installed package, you can disable packages one by one until you can no longer reproduce the issue. Restart (`cmd-q`) or reload (`cmd-ctrl-alt-l`) Atom after you disable each package to make sure it's completely gone.
+
+When you find the problematic package, you can disable or uninstall the package, and consider creating an issue on the package's GitHub repository.
+
+## Check your config files
+
+You might have defined some custom functionality or styles in Atom's [Init script or Stylesheet]. In some situations, these personal hacks might be causing problems so try clearing those files and restarting Atom.
+
+## Check for errors in the developer tools
+
+When an error is thrown in Atom, the developer tools are automatically shown with the error logged in the Console tab. However, if the dev tools are open before the error is triggered, a full stack trace for the error will be logged:
+
+![devtools error]
+
+If you can reproduce the error, use this approach to get the full stack trace. The stack trace might point to a problem in your [Init script][init script or stylesheet] or a specific package you installed, which you can then disable and report an issue on its GitHub repository.

+# Writing specs
+
+Atom uses [Jasmine](http://jasmine.github.io/2.0/introduction.html) as its spec framework. Any new functionality should have specs to guard against regressions.
+
+## Create a new spec
+
+[Atom specs](https://github.com/atom/atom/tree/master/spec) and [package specs](https://github.com/atom/markdown-preview/tree/master/spec) are added to their respective `spec` directory. The example below creates a spec for Atom core.
+
+0. Create a spec file
+
+  Spec files **must** end with `-spec` so add `sample-spec.coffee` to `atom/spec`.
+
+0. Add one or more `describe` methods
+
+  The `describe` method takes two arguments, a description and a function. If the description explains a behavior it typically begins with `when` if it is more like a unit test it begins with the method name.
+
+  ```coffee
+  describe "when a test is written", ->
+    # contents
+  ```
+
+  or
+
+  ```coffee
+  describe "Editor::moveUp", ->
+    # contents
+  ```
+
+0. Add one or more `it` method
+
+  The `it` method also takes two arguments, a description and a function. Try and make the description flow with the `it` method. For example, a description of `this should work` doesn't read well as `it this should work`. But a description of `should work` sounds great as `it should work`.
+
+  ```coffee
+  describe "when a test is written", ->
+    it "has some expectations that should pass", ->
+      # Expectations
+  ```
+
+0. Add one or more expectations
+
+  The best way to learn about expectations is to read the [jasmine documentation](http://jasmine.github.io/1.3/introduction.html#section-Expectations) about them. Below is a simple example.
+
+  ```coffee
+  describe "when a test is written", ->
+    it "has some expectations that should pass", ->
+      expect("apples").toEqual("apples")
+      expect("oranges").not.toEqual("apples")
+  ```
+
+## Asynchronous specs
+
+Writing Asynchronous specs can be tricky at first. Some examples.
+
+0. Promises
+
+  Working with promises is rather easy in Atom. You can use our `waitsForPromise` function.
+
+  ```coffee
+    describe "when we open a file", ->
+      it "should be opened in an editor", ->
+        waitsForPromise ->
+          atom.workspace.open('c.coffee').then (editor) ->
+            expect(editor.getPath()).toContain 'c.coffee'
+  ```
+
+  This method can be used in the `describe`, `it`, `beforeEach` and `afterEach` functions.
+
+  ```coffee
+  describe "when we open a file", ->
+    beforeEach ->
+      waitsForPromise ->
+        atom.workspace.open 'c.coffee'
+
+    it "should be opened in an editor", ->
+      expect(atom.workspace.getActiveEditor().getPath()).toContain 'c.coffee'
+
+  ```
+
+  If you need to wait for multiple promises use a new `waitsForPromise` function for each promise. (Caution: Without `beforeEach` this example will fail!)
+
+  ```coffee
+  describe "waiting for the packages to load", ->
+
+    beforeEach ->
+      waitsForPromise ->
+        atom.workspace.open('sample.js')
+      waitsForPromise ->
+        atom.packages.activatePackage('tabs')
+      waitsForPromise ->
+        atom.packages.activatePackage('tree-view')
+
+    it 'should have waited long enough', ->
+      expect(atom.packages.isPackageActive('tabs')).toBe true
+      expect(atom.packages.isPackageActive('tree-view')).toBe true
+  ```
+
+0. Asynchronous functions with callbacks
+
+  Specs for asynchronous functions can be done using the `waitsFor` and `runs` functions. A simple example.
+
+  ```coffee
+  describe "fs.readdir(path, cb)", ->
+    it "is async", ->
+      spy = jasmine.createSpy('fs.readdirSpy')
+
+      fs.readdir('/tmp/example', spy)
+      waitsFor ->
+        spy.callCount > 0
+      runs ->
+        exp = [null, ['example.coffee']]
+        expect(spy.mostRecentCall.args).toEqual exp
+        expect(spy).toHaveBeenCalledWith(null, ['example.coffee'])
+  ```
+
+For a more detailed documentation on asynchronous tests please visit the [jasmine documentation](http://jasmine.github.io/1.3/introduction.html#section-Asynchronous_Support).
+
+
+## Running specs
+
+Most of the time you'll want to run specs by triggering the `window:run-package-specs` command. This command is not only to run package specs, it is also for Atom core specs. This will run all the specs in the current project's spec directory. If you want to run the Atom core specs and **all** the default package specs trigger the `window:run-all-specs` command.
+
+To run a limited subset of specs use the `fdescribe` or `fit` methods. You can use those to focus a single spec or several specs. In the example above, focusing an individual spec looks like this:
+
+```coffee
+describe "when a test is written", ->
+  fit "has some expectations that should pass", ->
+    expect("apples").toEqual("apples")
+    expect("oranges").not.toEqual("apples")
+```
