	3 ## Building GN itself

	4

	5 GN is part of the Chromium tree. If you have a Chromium checkout, you

	6 already have the source and you can do `ninja -C out/Debug gn` to

	7 build it.

	8

	9 To build gn using gn, run (in the root `src` directory):

	10

	11 ```

	12 gn gen out/Default

	13 ninja -C out/Default gn

	14 ```

	15

	16 Change `out/Default` as necessary to put the build directory where you

	17 want.

	18

	19 ## Running GN's unit tests

	20

	21 ```

	22 ninja -C out/Default gn_unittests && out/Default/gn_unittests

	23 ```
