+
+##### To verify your changes
+Any config can be verified, to ensure your changes are valid against the yaml and orb schemas, 
+from the root of the project, run: `circleci config validate .circleci/config.yml --org-slug gh/gresham-computing --token $CIRCLE_TOKEN`
+
+##### Possible errors:
+- Your file must be encoded in UTF-8 (powershell defaulted to UTF-16)
+- Must use Unix style line endings (LF, not CRLF)

+## Release Process
+
+Here at Gresham, we use this component for a base for the auth server, our developing branch is 1.3.x and any feature branches should be made off of that branch.
+
+A release build can be invoked by running .circleci/run_release_workflow.sh shell script. It uses CircleCI API to trigger the release workflow and it requires a CIRCLE_TOKEN environment variable with a personal CircleCI API token to be set. Once triggered, the build will bump appropriate versions to release and then proceed to bump them to next snapshot.
