# - setup: to find out which projects changed compared to main
# - test: test the changed projects in a matrix
# - build: build the changed projects in a matrix, this creates a branch to save the evaluated projects
# - docs: build the dev docs, collecting the evaluated projects from `evaluated` and the new branch
