## Installing Git
The source code of IntelliJ IDEA Community Edition is stored in a Git repository. 
Therefore, in order to check out the sources, you need to have Git installed. 
We recommend using the 
[msys git](http://code.google.com/p/msysgit/)
distribution on Windows and 
[git-osx-installer](http://code.google.com/p/git-osx-installer/) 
on Mac.

## Checking Out the Code

You can check out the code either by using IntelliJ IDEA or from the command line.


**Checking out from IntelliJ IDEA:**
 
* Select **VCS \| Checkout from Version Control \| Git** from the main menu

* In the **Git Repository URL** field, enter ```git://git.jetbrains.org/idea/community.git```

**Checking out from the command line**

Please execute the following command:
```
git clone git://git.jetbrains.org/idea/community.git idea
```

The

## Forking on GitHub

As an alternative to checking out the official repository, you can fork the GitHub mirror of the IntelliJ IDEA source code, make changes in your own fork, and send us a pull request.

The GitHub mirror can be found at 
[https://github.com/JetBrains/intellij-community](https://github.com/JetBrains/intellij-community)

## Building and Running from the IDE

To develop IntelliJ IDEA, you can use either
[IntelliJ IDEA Community Edition](https://www.jetbrains.com/idea/download/)
or
[IntelliJ IDEA Ultimate](https://www.jetbrains.com/idea/download/).

**Building and running the code**

*  Make sure you have the
   [Groovy plugin](https://plugins.jetbrains.com/plugin/1524)
   enabled by going to **Settings \| Plugins** and enabling **Groovy** plugin checkbox.

   ![Groovy plugin](/img/getting_started/checkout_and_build_community/groovy_plugin_enabled.png)

   Parts of IntelliJ IDEA are written in Groovy, and you will get compilation errors if you don't have the plugin enabled

*  Make sure you have the UI Designer plugin enabled.
   Most of IntelliJ IDEA's UI is built using the UI Designer, and the version you build will not run correctly if you don't have the plugin enabled

   ![UI Designer plugin](/img/getting_started/checkout_and_build_community/ui_designer_plugin_enabled.png)

*  Open the directory with the source code as a directory-based project

*  Configure a Java SDK named *IDEA jdk* (case sensitive), pointing to an installation of JDK 1.8

   ![Configure SDK](/img/getting_started/checkout_and_build_community/configure_sdk.png)

*  Add **lib\\tools.jar** from the JDK installation directory to the classpath of IDEA JDK

   ![tools.jar](/img/getting_started/checkout_and_build_community/tools_jar.png)

*  Use **Build \| Make Project** to build the code

*  To run the code, use the provided shared run configuration *IDEA*

   ![IDEA Run Configuration](/img/getting_started/checkout_and_build_community/idea_run_configuration.png)

## Building and Running from the Command Line
To build the distribution archive of *IntelliJ IDEA Community Edition*, execute
[build.xml](https://github.com/JetBrains/intellij-community/blob/master/build.xml)

Ant build script in the root directory of the source code.
