+Build instructions
+------------------
+
+Make sure ambuild2 is installed: https://github.com/alliedmodders/ambuild
+
+Configure the build (`--hl2sdk-root` specifies the path where the all SDKs have been installed by `support/checkout-deps.sh` and `--mms_path` is the path to Metamod: Source).
+
+If you only want to compile using a specific SDK you can hack around the requirement to build for all SDKs by modifying the calls to the SDK constructor in the assignment to `PossibleSDKs` in `AMBuildScript` and setting the `platforms` parameter to \[\] for all SDKs that you don't want to compile for.
+
+### Windows
+
+Use Command Prompt as Gitbash doesn't handle the path arguments correctly.
+
+```
+mkdir build
+cd build
+python ../configure.py --hl2sdk-root C:\Users\user\Documents\GitHub --mms_path C:\Users\user\Documents\GitHub\metamod-source
+```
+
+Build:
+```
+ambuild
+```
