+## Installation
+
+```console
+pip install mongodb-atlas-haystack
+```
+
+## Contributing
+
+`hatch` is the best way to interact with this project, to install it:
+```sh
+pip install hatch
+```
+
+To run the linters `ruff` and `mypy`:
+```
+hatch run lint:all
+```
+
+To run all the tests:
+```
+hatch run test
+```
+
+Note: you need your own MongoDB Atlas account to run the tests: you can make one here: 
+https://www.mongodb.com/cloud/atlas/register. Once you have it, export the connection string
+to the env var `MONGO_CONNECTION_STRING`. If you forget to do so, all the tests will be skipped.
