 See [docs](https://docs.drips.network) for a high-level introduction and documentation.
 
+# Organization of the repository
+
+The `main` branch is always in-development, it contains the newest
+version of the contracts that may not be deployed anywhere.
+
+The hashes of the git commits that were used for deployments can be found
+in the `deployments` directory, in the JSON files under the `Commit hash` key.
+These commits are also git tagged using the `v2_<chain_name>_deploy` naming scheme,
+e.g. `v2_ethereum_deploy`.
+
+The deployed contracts for the old, v1 version of the protocol can be found on the `v1` branch.
