 # :tada: Contributing to Atom :tada:
 
-These are just guidelines, not rules, use your best judgement and feel free
-to propose changes to this document in a pull request.
+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 use the feedback form in the application or email
+[atom@github.com](mailto:atom@github.com). 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
+
+* 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.
+* 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.

-    and [CSS](https://github.com/styleguide/css) styleguides
-  * Include thoughtfully worded [Jasmine](http://pivotal.github.com/jasmine)
-    specs
-  * Avoid placing files in `vendor`. 3rd-party packages should be added as a
-    `package.json` dependency.
-  * Files end with a newline.

+* 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://jasmine.github.io/) 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)
-  * 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:
-    * :lipstick: when improving the format/structure of the code
-    * :racehorse: when improving performance
-    * :non-potable_water: when plugging memory leaks
-    * :memo: when writing docs
+
+* 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
+    * :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.

+## Removing Bindings
+
+When the keymap system encounters a binding with the `unset!` directive as its
+command, it will treat the current element as if it had no key bindings matching
+the current keystroke sequence and continue searching from its parent. If you
+want to remove a binding from a keymap you don't control, such as keymaps in

+## Forcing Chromium's Native Keystroke Handling
+
+If you want to force the native browser behavior for a given keystroke, use the
+`native!` directive as the command of a binding. This can be useful to enable
+the correct behavior in native input elements, for example. If you apply the
+`.native-key-bindings` class to an element, all the keystrokes typically handled
+by the browser will be assigned the `native!` directive.

+## 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
+
+### Packages
+
+#### GET /api/packages
+
+Returns a list of all packages in the following format:
+```json
+  [
+    {
+      "releases": {
+        "latest": "0.6.0"
+      },
+      "name": "thedaniel-test-package",

+        "type": "git",
+        "url": "https://github.com/thedaniel/test-package"
+      }
+    },
+    ...
+  ]
+```
+
+#### 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"
+    },
+    "name": "thedaniel-test-package",
+    "repository": {

+      (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.

+
+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

+  }
+```
+
+
+### 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.
+- **400** - Git tag not found / Repository inaccessible
+- **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
+
+### Atom updates
+
+#### GET /api/updates
+
+Atom update feed, following the format expected by [Squirrel](https://github.com/Squirrel/).
+
+Returns:
+
+```

+### Exception: "TypeError: Unable to watch path"
+
+If you get following error with a big traceback right after Atom starts:

+  ```
+
+you have to increase number of watched files by inotify.  For testing if

+
+## 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.

+# 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`.

+# Writting 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` method
+
+  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 arugments, 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 [jamsine documentation](http://jasmine.github.io/2.0/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")
+  ```
+
+## Runnings 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")
+```
