+## Local testing
+
+For developoment, we provide a docker image containing gromacs and multiple python versions to test against.  
+To run the test locally, you must:
+- install docker
+- install [act](https://github.com/nektos/act), easiest option is with github cli
+    - install github cli (`gh`)
+    - `gh extension install https://github.com/nektos/gh-act`
+- run tests with `gh extension exec act -j test --artifact-server-path ./artifacts`
+    - customize which python versions to test in `tox.ini` 
+    - html coverage report is exported into `artifacts`
