+# GitLab Triage
 
-Gitlab Triage provides a wrapper for the `gitlab-triage` gem, enabling automated
-triage of issues, merge requests and epics based on the triage policy.
+GitLab Triage provides a wrapper for the [`gitlab-triage`](https://gitlab.com/gitlab-org/ruby/gems/gitlab-triage) gem, enabling automated triage of issues, merge requests and epics based on a triage policy.
 
+## Settings
+
+The following settings are used to configure the `gitlab-triage` tool:
+
+* `GITLAB_TOKEN` a valid GitLab API token. When running in local development, generate your own [GitLab Personal Access Token](https://docs.gitlab.com/user/profile/personal_access_tokens/).
+* `GITLAB_URL` a valid GitLab host URL. For UIS DevOps the host is `https://gitlab.developers.cam.ac.uk/`
+* `TRIAGE_SOURCE_ID` the id of the target GitLab `project` or `group`.
+* `TRIAGE_SOURCE_TYPE` can be either `projects` or `groups` corresponding to the associated `TRIAGE_SOURCE_ID`.
+* `TRIAGE_POLICY_FILE` a YAML file containing a valid triage policy.
+
+## Local Development
+
+We use pre-commit to check linting locally and in the CI pipeline. Before you can run pre-commit hooks locally, you need to have the pre-commit package manager installed:
+
+```sh
+pip install pre-commit
+```
+
+Following this, install the pre-commit hooks locally by running:
+
+```sh
+pre-commit install
+```
+
+The local development environment uses the settings loaded from `local-dev-settings.env`. You will need to generate your own [GitLab Personal Access Token](https://docs.gitlab.com/user/profile/personal_access_tokens/) store this new token in your own 1Password vault and update `GITLAB_TOKEN` in `local-dev-settings.env` to the 1Password secret reference pointing to the new token.
+
+We include a working example triage policy `./triage-policies/example-triage-policy.yml` that operates on project `uis/devops/experiments/av603/misc`. When developing you own triage policy, refer to the field names defined in [`gitlab-triage`](https://gitlab.com/gitlab-org/ruby/gems/gitlab-triage) and ensure the policy only affects the intended `TRIAGE_SOURCE_ID` by limiting the project path. For example:
+
+```yaml
+ruby:
+    "project_path.include?('uis/devops/experiments/av603/misc')"
+```
+
+If the `gitlab-triage` gem becomes stale, the version can be refreshed by updating the target version inside the `Gemfile` and regenerating the `Gemfile.lock`. To update the `Gemfile.lock` you can either install the target version of `Ruby` and `bundler` on your local machine and run `bundle install`:
+
+```sh
+brew install ruby@3.0
+gem install bundler --user-install
+bundle install --path vendor/bundle
+```
+
+OR by building an image from the `base` target, mount the working directory containing the `Gemfile` inside a container and running `bundle install` from within the container:
+
+```sh
+docker build --target base -t gitlab-triage-base:latest .
+docker run -it -v "$(pwd):/usr/src/app" -w /usr/src/app gitlab-triage-base:latest /bin/bash
+bundle install --path vendor/bundle
+bundle update
+```
