## System requirements

Building and running on Linux is officially supported, mac build is not. If you
are willing to run emulator based tests locally, KVM is required. You may check
if `/dev/kvm` exists on the system, or follow the [Enable KVM](#enable-kvm)
section.

1. Follow up [chromium for linux](../linux/build_instructions.md) to setup
chromium environment.

2. Edit your `.gclient` to add `fuchsia` to the `target_os` list. The file
   should look similar to this:

   ```
   solutions = [
     {
       "url": "https://chromium.googlesource.com/chromium/src.git",
       "managed": False,
       "name": "src",
       "custom_deps": {},
       "custom_vars": {}
     }
   ]
   target_os = ['fuchsia']
   ```

2. Run `gclient sync`

3. Create a build directory:

   ```shell
   $ gn gen out/fuchsia --args="is_debug=false dcheck_always_on=true is_component_build=false target_os=\"fuchsia\""
   ```
