 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

 ## 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 and stack traces to include.
+* 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.

+# 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.
+
+*This API should be considered pre-release and is subject to change (though significant breaking changes are unlikely).*
+
+### 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`.
+
+# API Resources
+
+## Packages
+
+### Listing packages
+
+#### GET /api/packages
+
+Parameters:
+
+- **page** (optional)
+
+Returns a list of all packages in the following format:
+```json
+  [
+    {
+      "releases": {
+        "latest": "0.6.0"
+      },
+      "name": "thedaniel-test-package",
+      "repository": {
+        "type": "git",
+        "url": "https://github.com/thedaniel/test-package"
+      }
+    },
+    ...
+  ]
+```
+
+Results are paginated 30 at a time, and links to the next and last pages are
+provided in the `Link` header:
+
+```
+Link: <https://www.atom.io/api/packages?page=1>; rel="self",
+      <https://www.atom.io/api/packages?page=41>; rel="last",
+      <https://www.atom.io/api/packages?page=2>; rel="next"
+```
+
+### Showing package details
+
+#### 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": {

+    },
+    "versions": [
+      (see single version output below)
+      ...,
+    ]
+  }
+```
+
+### Creating a package
+
+#### 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
+
+### Deleting a package
+
+#### DELETE /api/packages/:package_name
+
+Delete a package; requires authentication.
+
+Returns:
+
+- **204** - Success
+- **400** - Repository is inaccessible
+- **401** - Unauthorized
+
+### Renaming a package
+
+Packages are renamed by publishing a new version with the name changed in `package.json`
+See [Creating a new package version](#creating-a-new-package-version) for details.
+
+Requests made to the previous name will forward to the new name.
+
+### 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"
+    },
+    "dependencies": {
+      "async": "~0.2.6",
+      "pegjs": "~0.7.0",
+      "season": "~0.13.0"
+    },
+    "description": "Expand snippets matching the current prefix with `tab`.",
+    "dist": {
+      "tarball": "https://codeload.github.com/..."
+    },
+    "engines": {
+      "atom": "*"
+    },
+    "main": "./lib/snippets",
+    "name": "thedaniel-test-package",
+    "publishConfig": {
+      "registry": "https://...",
+    },
+    "repository": {
+      "type": "git",
+      "url": "https://github.com/thedaniel/test-package.git"
+    },
+    "version": "0.6.0"
+  }
+```
+
+
+### Creating a new package version
+
+#### POST /api/packages/:package_name/versions
+
+Creates a new package version from a git tag; requires authentication. If `rename`
+is not `true`, the `name` field in `package.json` *must* match the current package
+name.
+
+#### 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.
+- **rename** - Boolean indicating whether this version contains a new name for the package.
+
+#### Returns
+
+- **201** - Successfully created. Returns created version.
+- **400** - Git tag not found / Repository inaccessible / package.json invalid
+- **409** - Version exists
+
+### Deleting 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
+
+### Listing user stars
+
+#### GET /api/users/:login/stars
+
+List a user's starred packages.

+# 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 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.
