You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -c with the switch command. Example: git switch -c Or undo this operation with: git switch - Turn off this advice by setting config variable advice.detachedHead to false HEAD is now at 9e96974 Update the Guard to work as a singleton class + Tidy up [rtd-command-info] start-time: 2026-05-19T21:45:59.656628Z, end-time: 2026-05-19T21:45:59.695586Z, duration: 0, exit-code: 0 cat .readthedocs.yaml # Read the Docs configuration file # Required version: 2 # Build documentation with Sphinx sphinx: configuration: doc/conf.py # Exclude all submodules submodules: exclude: all # Optionally build your docs in additional formats such as PDF and ePub formats: - htmlzip # Optionally set the build image build: os: ubuntu-24.04 tools: python: "3.11" apt_packages: - graphviz - cmake - ninja-build - clang # Optionally set the version of Python and requirements required to build your docs python: install: - requirements: doc/requirements.txt - method: pip path: .
