 This repository offers a [cookiecutter](https://cookiecutter.readthedocs.io)
 for creating your own Zarr store implementation.
 
-To use it:
+### Setting up the repo
 
 ```sh
 pip install cookiecutter
 cookiecutter https://github.com/zarr-developers/cookiecutter-zarr-store
 ```
-And answer the questions :smile:
+After launching above commands, you'll be see a few questions on your terminal. For the first question use the name of the store you want to work with. E.g. `zip_store` for Zip Store, `sqlite_store` for SQLitreStore, `mongodb_store` for MongoDBStore and so on.
+
+For remaining questions use the value indicated in the `[ ]`. These are the default values set by the maintainers.
+
+### Once you're done with above setup you can move to
+
+- [storage.py](https://github.com/zarr-developers/zarr-python/blob/main/zarr/storage.py) and start separating the desired store's code and integrating into your repository under `zarr-something-short/storage.py`
+- Pick up corresponding tests from [tests_storage.py](https://github.com/zarr-developers/zarr-python/blob/main/zarr/tests/test_storage.py) and start adding them into your repository under `zarr-something-short/tests/tests_storage.py`
+
+### Testing the code
+
+Before running tests make sure to install `pytest` via `pip install pytest`
 
 In order to run the tests, be sure to initialize git:
