+```
+### Build templates
+
+They have definitions on what kind of images we want to build - for section or for one specific board:
+
+```
+userpatches/targets-release-apps.template
+userpatches/targets-release-community-maintained.template
+userpatches/targets-release-nightly.template
+userpatches/targets-release-standard-support.template
+```
+
+From those templates we are [autogenerating](https://github.com/armbian/os/blob/main/.github/workflows/recreate-matrix.yml#L147-L438) YAML files, which are passed to build matrix as input. Make sure to review generated YAML files if they have wanted build targets with correct exensions enabled.
+
+### Blacklisting
+
+Autogeneration is excluded for boards that are on black lists:
+
+```
+userpatches/targets-automation.blacklist
+userpatches/targets-automation-nightly.blacklist
+```
+
+We do this if we are not happy with the automation outcomes and want to define build targets in the template.
+
+### Extensions
+
+Each board variant can have additional extensions and they are defined in this file:
+
+```
+userpatches/targets-extensions.map
+```
+
+Example:
+
+```
+khadas-edge2,legacy:vendor:,ENABLE_EXTENSIONS="image-output-oowow,v4l2loopback-dkms,mesa-vpu"
+```
