+    * Your IdeaVim-specific Vim initialization commands
+
+You can read your ~/.vimrc file from ~/.ideavimrc using this command:
+
+    source ~/.vimrc
+
+Note, that IdeaVim currently parses ~/.ideavimrc file via simple pattern matching,
+see [VIM-669](http://youtrack.jetbrains.com/issue/VIM-669) for proper parsing
+of VimL files.
+
+Also note that if you have overridden the `user.home` JVM option, this
+will affect where IdeaVim looks for your .ideavimrc file.  For example, if you
+have `-Duser.home=/my/alternate/home` then IdeaVim will source
+`/my/alternate/home/.ideavimrc` instead of `~/.ideavimrc`.
+
+
+Emulated Vim Plugins
+--------------------
+
+IdeaVim extensions emulate some plugins of the original Vim. In order to use
+IdeaVim extensions, you have to enable them via this command in your ~/.ideavimrc:
+
+    set <extension-name>
+
+Available extensions:
+
+* surround
+    * Emulates [vim-surround](https://github.com/tpope/vim-surround)
+    * Commands: `ys`, `cs`, `ds`, `S`
+* multiple-cursors
+    * Emulates [vim-multiple-cursors](https://github.com/terryma/vim-multiple-cursors)
+    * Commands: `<A-n>`, `<A-x>`, `<A-p>`, `g<A-n>`

+Ex commands or via `:map` command mappings:

+
+### Where to Start
+
+In order to contribute to IdeaVim you should have some understanding of Java.
+
+See also these docs on the IntelliJ API:
+
+* [IntelliJ architectural overview](http://confluence.jetbrains.com/display/IDEADEV/IntelliJ+IDEA+Architectural+Overview)
+* [IntelliJ plugin development resources](http://confluence.jetbrains.com/display/IDEADEV/PluginDevelopment)
+
+You can start by picking relatively simple tasks that are tagged with
+[#patch_welcome](http://youtrack.jetbrains.com/issues/VIM?q=%23patch_welcome)
+in the issue tracker.
+
 
 ### Development Environment
 
 1. Fork IdeaVim on GitHub and clone the repository on your local machine.
 
-2. Open the project in IntelliJ IDEA 12+ (Community or Ultimate) using "File |
-   Open... | /path/to/ideavim".
+2. Import the project from existing sources in IntelliJ IDEA 2018.1 or newer (Community or
+   Ultimate) using "File | New | Project from Existing Sources..." or "Import
+   Project" from the start window.
 
-3. Set up a JDK if you haven't got it yet. Use "File | Project Structure | SDKs
-   | Add new JDK".
+    * In the project wizard select "Import project from external model | Gradle"
 
-4. Set up an IntelliJ plugin SDK using "File | Project Structure | SDKs | Add
-   new IntelliJ IDEA Plugin SDK". The correct path to your current installation
-   of IntelliJ will be suggested automatically. You will be prompted to select a
-   JDK for your plugin SDK. Select the JDK from the previous step. You
-   **should** name your plugin SDK `IntelliJ Plugin SDK` in order to match the
-   name in the project settings stored in the Git repository.
+    * Select your Java 8+ JDK as the Gradle JVM, leave other parameters unchanged
 
-5. Select a project SDK for your project using "File | Project Structure |
-   Project | Project SDK". Choose the plugin SDK you have created at the
-   previous step.
+3. Run your IdeaVim plugin within IntelliJ via a Gradle task
 
-6. Build IdeaVim and run IntelliJ with IdeaVim enabled using the "IdeaVim" run
-   configuration (use "Run | Run... | IdeaVim").
+    * Select "View | Tool Windows | Gradle" tool window
     
-7. In order to be able to run tests in your IntelliJ edition uncomment the
-   appropriate lines in the constructor of the `VimTestCase` class.
+    * Launch "ideavim | intellij | runIde" from the tool window
+
+4. Run IdeaVim tests via a Gradle task
+
+    * Select "View | Tool Windows | Gradle" tool window
+    
+    * Launch "ideavim | verification | test" from the tool window
+
+5. Build the plugin distribution by running `./gradlew clean buildPlugin` in the
+   terminal in your project root.
+
+    * The resulting distribution file is build/distributions/IdeaVim-VERSION.zip
+
+    * You can install this file using "Settings | Plugins | Install plugin
+      from disk"
