+This repository contains (re-)implementations of some mods as separate branches derived from `master`. The list of supported mods can be found [here](https://github.com/FWGS/hlsdk-portable/wiki/Mods). Note that some branches are unstable and incomplete.
+
+To get the mod branch locally run the following git command:
+
+```
+git fetch origin asheep:asheep
+```
+
+This is considering that you have set **FWGS/hlsdk-portable** as an `origin` remote and want to fetch `asheep` branch.

 # Obtaining source code
 
 Either clone the repository via [git](`https://git-scm.com/downloads`) or just download ZIP via **Code** button on github. The first option is more preferable as it also allows you to search through the repo history, switch between branches and clone the vgui submodule.
