+## Get the code
+

Use google markdown style

I assume you mean the "replace ) with ."? I couldn't find any other violation of
the style guide. If so - done.

+ 1) Run `fetch infra`
+ 1) Run `infra/go/env.py`
+
+### Quick Setup
+
+If you are on Linux you can run the [quicksetup script](quicksetup.sh) like so:
+
+```shell
+cd /where/you/want/source/code
+wget -O- "https://chromium.googlesource.com/infra/infra/+/master/go/quicksetup.sh?format=TEXT" | base64 -d | bash
+```
+
+This will create a self-contained `cr-infra-go-area` directory and populate it
+will all necessary tools and source for using or contributing to Chromium's Go
+Infrastructure. Once run, look in `cr-infra-go-area/infra/go/src` for the
+editable source code.
