+# infra/config folder
+
+This folder contains WebRTC project-wide configurations for Chrome infra
+services, mainly the CI system ([console][]).
+
+`*.cfg` files are the actual configuration that [LUCI][luci-config] looks at.
+They are in *protocol buffer text format*. For example,
+[cr-buildbucket.cfg](cr-buildbucket.cfg) defines builders.
+
+However, they are all automatically generated from the [Starlark][] script
+[config.star](config.star) that defines a unified config using **[lucicfg][]**.
+The main body of the config is at the bottom of the file, following all the
+helper definitions.
+
+`lucicfg` should be available as part of depot_tools. After editing
+[config.star](config.star) you should run `lucicfg generate config.star` to
+re-generate `*.cfg` files. Check the diffs in generated files to confirm that
+your change worked as expected. Both the code change and the generated changes
+need to be committed together.
+
+## Uploading changes
+
+It is recommended to have a separate checkout for this branch, so switching
+to/from it does not populate/delete all files in the master branch.
+
+Initial setup:
+
+```bash
+git clone https://webrtc.googlesource.com/src/
+```
+
+Now you can create a new branch to make changes:
+
+```bash
+git new-branch add-new-builder
+# edit/generate files
+git commit -a
+git cl upload
+```
+
+Changes can be reviewed on Gerrit and submitted with commit queue as usual.
+
+### Activating the changes
+
+Any changes to this directory go live soon after landing, without any additional
+steps. You can see the status or force a refresh of the config at
+[luci-config][].
