+## Adding a module

+
+
+To contibute a new hook, or provider fork this repository and create a new go module, it will then be discoverable by `make workspace-init` and `make workspace-update`.
+
+create and setup new provider directory (requires jq)

+
+## Documentation
+
+Any published modules must have documentation in their root directory, explaining the basic purpose of the module as well as installation and usage instructions.
+Instructions for how to develop a module should also be included (required system dependencies, instructions for testing locally, etc).
+
+## Testing
+
+Any published modules must have reasonable test coverage.
+
+Testing packages provide shared testing functionality across OpenFeature components, avoiding duplication.
+
+To test all go modules
+```
+make test
+```
+
+## Releases
+
+This repo uses _Release Please_ to release packages. Release Please sets up a running PR that tracks all changes for the library components, and maintains the versions according to [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/), generated when [PRs are merged](https://github.com/amannn/action-semantic-pull-request).
+Merging the Release Please PR will create a GitHub release with updated library versions.
+
+## Dependencies
+
+The [GO-SDK](https://github.com/open-feature/go-sdk) should be a _peer dependency_ of your module.
