-Building
+Installing Build Tools
+----------------------
+
+To install the required build tools please run the script for your
+operating system found in the env_setup_scripts directory. This will
+download the required tools from
+https://firmware.ardupilot.org/Tools/AM32-tools/ and unpack them in
+tools. It will also setup your vscode settings for your OS.
+
+Runing VSCode
+-------------
+
+When you run vscode it will recommend you install some key extensions:
+
+ - C/C++ tools
+ - Cortex-Debug
+ - Makefile Tools
+
+You will need to install these before doing a build.
+
+Command Line Build
+------------------
+
+To build with the command line use the command "make". If your
+environment is setup correctly you should be able to tab complete the
+available targets. Otherwise you can run "make targets" to see the
+available build targets.
+
+CI Builds
+---------
+
+All of the bootloaders are automatically built in CI using github
+actions. See the Actions tab on
