 ## Run formatting automation/tests
 
-To format code in the repo, simply run `./gradlew format` at the base of the repo.
+Airbyte runs a code formatter as part of the build to enforce code styles. You should run the formatter yourself before submitting a PR (otherwise the build will fail).
+
+The command to run formatting varies slightly depending on which part of the codebase you are working in.
+### Platform
+If you are working in the platform run `SUB_BUILD=PLATFORM ./gradlew format` from the root of the repo.
+
+### Connector
+If you are working on an individual connectors run: `./gradlew :airbyte-integrations:<directory the connector is in e.g. source-postgres>:format`.
+
+### Connector Infrastructure
+Finally, if you are working in any module in `:airbyte-integrations:bases` or `:airbyte-cdk:python`, run `SUB_BUILD=CONNECTORS_BASE ./gradlew format`.
