+Contributing
+------------
+We welcome contributors from the community.  Please consider posting issues, and taking issues and posting PRs.
+
+To ensure code quality and to prevent accidental commits into the default branch, please set up the use of our pre-commit
+hooks.
+
+1. modify the permissions to executable on the bash script called `prevent_commit_to_main.sh` in this directory: `chmod +x prevent_commit_to_main.sh`
+2. install pre-commit in your working environment `conda install pre-commit`
+3. initialize pre-commit (one time only) `pre-commit install`
+
+Thereafter your code will be linted by black and isort and checked against flake8 before you can commit.
+If it fails by black or isort, just rerun and it should pass (black and isort will modify the files so should
+pass after they are modified).  If the flake8 test fails please see the error messages and fix them manually before
+trying to commit again
