The documentation is available at https://synaptics-synap.github.io/doc/
To build the documentation you need to clone the framework git repository along with this repository:
$ git clone https://github.com/synaptics-astra/synap-framework.git -b ${VERSION} ../framework
where ${VERSION} is an Astra version tag such as v1.0.0..
Once you cloned the framework repository you can launch the build with the following command:
$ ./build.sh
