+## FAQ
+
+### Where do I start?
+
+Check out [EditorView][EditorView] and [Editor][Editor] classes for a good
+overview of the main editor API.
+
+### How do I access these classes?
+
+Check out the [Atom][Atom] class docs to see what globals are available and
+what they provide.
+
+You can also require many of these classes in your package via:
+
+```coffee
+{EditorView} = require 'atom'
+```
+
+The classes available from `require 'atom'` are:
+  * [BufferedProcess][BufferedProcess]
+  * [BufferedNodeProcess][BufferedNodeProcess]
+  * [EditorView][EditorView]
+  * [Git][Git]
+  * [Point][Point]
+  * [Range][Range]
+  * [ScrollView][ScrollView]
+  * [SelectListView][SelectListView]
+  * [View][View]
+  * [WorkspaceView][WorkspaceView]
+  * [Workspace][Workspace]
+
+### How do I create a package?
+
+You probably want to read the [creating a package][creating-a-package]
+doc first and come back here when you are done.
+
+### Where are the node docs?
+
+Atom ships with node 0.11.10 and the comprehensive node API docs are available
+[here][node-docs].

+## Atom's View System
+
+### SpacePen Basics
+
+Atom's view system is built around the [SpacePen] view framework. SpacePen
+view objects inherit from the jQuery prototype, and wrap DOM nodes
+
+View objects are actually jQuery wrappers around DOM fragments, supporting all
+the typical jQuery traversal and manipulation methods. In addition, view objects
+have methods that are view-specific. For example, you could call both general
+and view-specific on the global `atom.workspaceView` instance:
+
+```coffeescript
+atom.workspaceView.find('atom-text-editor.active') # standard jQuery method
+atom.workspaceView.getActiveEditor()      # view-specific method
+```
+
+If you retrieve a jQuery wrapper for an element associated with a view, use the
+`.view()` method to retrieve the element's view object:
+
+```coffeescript

+
+### WorkspaceView
+
+The root of Atom's view hierarchy is a global called `atom.workspaceView`, which is a
+singleton instance of the `WorkspaceView` view class. The root view fills the entire
+window, and contains every other view. If you open Atom's inspector with
+`alt-cmd-i`, you can see the internal structure of `WorkspaceView`:
+
+![WorkspaceView in the inspector][workspaceview-inspector]
+
+#### Panes
+
+The `WorkspaceView` contains `prependToBottom/Top/Left/Right` and
+`appendToBottom/Top/Left/Right` methods, which are used to add Tool Panels. Tool
+panels are elements that take up screen real estate not devoted to text editing.
+In the example above, the `TreeView` is appended to the left, and the
+`CommandPanel` is appended to the top.
+
+```coffeescript
+# place a view to the left of the panes
+atom.workspaceView.appendToLeft(new MyView)
+
+# place a view below the panes
+atom.workspaceView.appendToBottom(new MyOtherView)
+```

-# Upgrading Your Syntax Theme
-
-Text editor content is now rendered in the shadow DOM, which shields it from being styled by global style sheets to protect against accidental style pollution. For more background on the shadow DOM, check out the [Shadow DOM 101][shadow-dom-101] on HTML 5 Rocks.
-
-Syntax themes are specifically intended to style only text editor content, so they are automatically loaded directly into the text editor's shadow DOM when it is enabled. This happens automatically when the the theme's `package.json` contains a `theme: "syntax"` declaration, so you don't need to change anything to target the appropriate context.
-
-When theme style sheets are loaded into the text editor's shadow DOM, selectors intended to target the editor from the *outside* no longer make sense. Styles targeting the `.editor` and `.editor-colors` classes instead need to target the `:host` pseudo-element, which matches against the containing `atom-text-editor` node. Check out the [Shadow DOM 201][host-pseudo-element] article for more information about the `:host` pseudo-element.
-
-Here's an example from Atom's light syntax theme. Note that the previous selectors intended to target the editor from the outside have been retained to allow the theme to keep working during the transition phase when it is possible to disable the shadow DOM.
-
-```css
-.editor-colors, :host { /* :host added */
-  background-color: @syntax-background-color;
-  color: @syntax-text-color;
-}
-
-.editor, :host { /* :host added */
-  .invisible-character {

-
-## Custom Tags
-
-Rather than adding classes to standard HTML elements to indicate their role, Atom now uses custom element names. For example, `<div class="workspace">` has now been replaced with `<atom-workspace>`. Selectors should be updated accordingly. Note that tag names have lower specificity than classes in CSS, so you'll need to take care in converting things.

-## Supporting the Shadow DOM
-
-Text editor content is now rendered in the shadow DOM, which shields it from being styled by global style sheets to protect against accidental style pollution. For more background on the shadow DOM, check out the [Shadow DOM 101][shadow-dom-101] on HTML 5 Rocks. If you need to style text editor content in a UI theme, you'll need to circumvent this protection for any rules that target the text editor's content. Some examples of the kinds of UI theme styles needing to be updated:
-
-* Highlight decorations
-* Gutter decorations
-* Line decorations
-* Scrollbar styling
-* Anything targeting a child selector of `.editor`
-
-During a transition phase, it will be possible to enable or disable the text editor's shadow DOM in the settings, so themes will need to be compatible with both approaches.
-
-### Shadow DOM Selectors
-
-Chromium provides two tools for bypassing shadow boundaries, the `::shadow` pseudo-element and the `/deep/` combinator. For an in-depth explanation of styling the shadow DOM, see the [Shadow DOM 201][shadow-dom-201] article on HTML 5 Rocks.
-
-#### ::shadow
-
-The `::shadow` pseudo-element allows you to bypass a single shadow root. For example, say you want to update a highlight decoration for a linter package. Initially, the style looks as follows:
-
-```css
-// Without shadow DOM support
-atom-text-editor .highlight.my-linter {
-  background: hotpink;
-}
-```
-
-In order for this style to apply with the shadow DOM enabled, you will need to add a second selector with the `::shadow` pseudo-element. You should leave the original selector in place so your theme continues to work with the shadow DOM disabled during the transition period.
-
-```css
-// With shadow DOM support
-atom-text-editor .highlight.my-linter,
-atom-text-editor::shadow .highlight.my-linter {
-  background: hotpink;
-}
-```
-
-Check out the [find-and-replace][find-and-replace] package for another example of using `::shadow` to pierce the shadow DOM.
-
-#### /deep/
-
-The `/deep/` combinator overrides *all* shadow boundaries, making it useful for rules you want to apply globally such as scrollbar styling. Here's a snippet containing scrollbar styling for the Atom Dark UI theme before shadow DOM support:
-
-```css
-// Without shadow DOM support
-.scrollbars-visible-always {
-  ::-webkit-scrollbar {
-    width: 8px;
-    height: 8px;
-  }
-
-  ::-webkit-scrollbar-track,
-  ::-webkit-scrollbar-corner {
-    background: @scrollbar-background-color;
-  }
-
-  ::-webkit-scrollbar-thumb {
-    background: @scrollbar-color;
-    border-radius: 5px;
-    box-shadow: 0 0 1px black inset;
-  }
-}
-```
-
-To style scrollbars even inside of the shadow DOM, each rule needs to be prefixed with `/deep/`. We use `/deep/` instead of `::shadow` because we don't care about the selector of the host element in this case. We just want our styling to apply everywhere.
-
-```css
-// With shadow DOM support using /deep/
-.scrollbars-visible-always {
-  /deep/ ::-webkit-scrollbar {
-    width: 8px;
-    height: 8px;
-  }
-
-  /deep/ ::-webkit-scrollbar-track,
-  /deep/ ::-webkit-scrollbar-corner {
-    background: @scrollbar-background-color;
-  }
-
-  /deep/ ::-webkit-scrollbar-thumb {
-    background: @scrollbar-color;
-    border-radius: 5px;
-    box-shadow: 0 0 1px black inset;
-  }
-}
-```
-
-### Context-Targeted Style Sheets
-
-The selector features discussed above allow you to target shadow DOM content with specific selectors, but Atom also allows you to target a specific shadow DOM context with an entire style sheet. The context into which a style sheet is loaded is based on the file name. If you want to load a style sheet into the editor, name it with the `.atom-text-editor.less` or `.atom-text-editor.css` extensions.
-
-```
-my-ui-theme/
-  stylesheets/
-    index.less                   # loaded globally
-    index.atom-text-editor.less  # loaded in the text editor shadow DOM
-```
-
-Check out this [style sheet](https://github.com/atom/decoration-example/blob/master/stylesheets/decoration-example.atom-text-editor.less) from the decoration-example package for an example of context-targeting.
-
-Inside a context-targeted style sheet, there's no need to use the `::shadow` or `/deep/` expressions. If you want to refer to the element containing the shadow root, you can use the `::host` pseudo-element.
-
-During the transition phase, style sheets targeting the `atom-text-editor` context will *also* be loaded globally. Make sure you update your selectors in a way that maintains compatibility with the shadow DOM being disabled. That means if you use a `::host` pseudo element, you should also include the same style rule matches against `atom-text-editor`.
