+#### Before Make Changes
+1. Install Pre-Commit Validation Hook
+   ```shell
+   pre-commit install
+   ```
+   - This ensures standard code formatting fixes and other checks run automatically on every commit
+   - Note 1: If [pre-commit](https://pre-commit.com/#intro) didn't already get installed, [install it](https://pre-commit.com/#install) via `pip install pre-commit`
+   - Note 2: To run the pre-commit changes manually, use `pre-commit run --all` before creating PR
+
+#### Before Creating PR
+
+1. Run Tests
+   ```shell
+   pytest
+   ```
+
+2. Run MyPy to check types
+   ```shell
+   mypy --config-file pyproject.toml
+   ```
+
+#### After Creating PR
+- Automated [validation workflows](.github/workflows) run for every PR.
+
+  Ensure any issues seen by them our fixed
+
+- Test the python packge created for a PR
+  1. Download and extract the zipped `.whl` artifact generated from the pypi workflow run for the PR.
+  2. Install (in your virtualenv) with `pip install /path/to/download*.whl>`
+  3. Start and use the application to see if it works fine
