+### Note on committing `ignition/deployments`
+
+This is a directory that contains build and deployment artifacts from `hardhat`.
+They aren't ignored, becuase they are used for types generation for frontend: if there's a smart contract already deployed, you may want to keep it in git, so a fresh clone would give you a working frontend.  
+
+However, several issues with hardhat are resolved by removing `ignition/deployments` directory, to start fresh deployment. These issues include:  
+
+```
+An unexpected error occurred:
+
+Error: Could not parse row {...
+```
+
+```
+[ MyTokenModule ] reconciliation failed ⛔

+The module contains changes to executed futures:

+In such cases, do `rm -rf ignition/deployments`, deploy the new contract, and commit the artifacts anew :)
