 ### Setting the Build Environment 
 
-These paths assume you cloned advligorts into your home directory, you will need to adjust to the paths for the directory you chose.
+For the RCG to know about your custom checkout it needs to know two things:
+1) The locations of your checkout: `RTS_VERSION`
+2) The what to call your new build (where to store build products): `RTS_VERSION`
 
+On installs without a `userapps` checkout you will also need to set `CDS_SRC`, this is common on very simple Cymac installs, but is not needed (because it is already set) on production/test-stand build/boot servers.
+
+
+##### Cymac with no `userapps` checkout example
 ```shell
 export RTS_VERSION=cymac-build
 export RCG_SRC=/home/$USER/git/advligorts/
 export CDS_SRC=/home/$USER/git/advligorts/src/include/ 
 ```
 
+##### Production/test-stand build server example
+```
+```shell
+export RTS_VERSION=5.1.3-bugfix
+export RCG_SRC=<checkout-location>/advligorts/
+```
 
 ### Allowing `rtcds` to Find your Custom Model
 In order for `rtcds` to find your model (the <model_name>.mdl file) the `RCG_LIB_PATH` env variable needs to have a path to the directory containing it. The best way to do that, is adding the directory path to the `RCG_LIB_PATH` line in the `/etc/advligorts/env` file.
