 ## Usage
 
+Make sure to initialize and update the 
+submodules when first cloning
+```
+git submodule update --init --recursive
+```
+
 Enter the build environment by running
 ```
 ./run-container.sh
 ```
 
 You have to run `make` from within the container because
 the ccache path is hardcoded as `/work/cache` in `buildroot-external/configs/pspl_cms_pi4_defconfig`
+There are 2 options when building `cms` and `cph`
+for CraterMaker Special and Copperhead respectively
+
+To build the image for CMS, run (in the container)
+```
+make build TARGET=cms
+```
 
-To build the image, run (in the container)
+For CPH, run (in the container)
 ```
-make config
-make -j$(nproc)
+make build TARGET=cph
 ```
