+* [colima](https://github.com/abiosoft/colima) can be used as the docker engine

-1. Execute `make`.
-2. Check the `firmware` directory for the latest firmware build.
+
+### Build firmware locally
+
+1. Execute `make` to build firmware for both halves or `make left` to only build firmware for the left hand side.
+2. Check the `firmware` directory for the latest firmware build. The first part of the filename is the timestamp when the firmware was built.
 
 ### Cleanup
 
-The built docker container and compiled firmware files can be deleted with `make clean`. This might be necessary if you updated your fork from V2.0 to V3.0 and are encountering build failures. 
+The built docker container and compiled firmware files can be deleted with `make clean`. This might be necessary if you updated your fork from V2.0 to V3.0 and are encountering build failures.
+
+Creating the docker container takes some time. Therefore `make clean_firmware` can be used to only clean firmware without removing the docker container. Similarly `make clean_image` can be used to remove the docker container without removing compiled firmware files.
