+
+### Conventional Commit messages
+
+This repository uses tool [Release Please](https://github.com/googleapis/release-please) to create GitHub and PyPi releases. It does so by parsing your
+git history, looking for [Conventional Commit messages](https://www.conventionalcommits.org/),
+and creating release PRs.
+
+Learn more by reading [How should I write my commits?](https://github.com/googleapis/release-please?tab=readme-ov-file#how-should-i-write-my-commits)
+
+## Testing
+
+### Run tests locally
+
+1. Run pytest to automatically run all tests:
+
+    ```bash
+    pytest
+    ```
+
+### CI Platform Setup
+
+Cloud Build is used to run tests against Google Cloud resources in test project: langchain-redis-query-testing.
+Each test has a corresponding Cloud Build trigger, see [all triggers][triggers].
+These tests are registered as required tests in `.github/sync-repo-settings.yaml`.
+
+#### Trigger Setup
+
+Cloud Build triggers (for Python versions 3.8 to 3.11) were created with the following specs:
+
+```YAML
+name: integration-test-pr-py38
+description: Run integration tests on PR for Python 3.8
+filename: integration.cloudbuild.yaml
+github:
+  name: langchain-google-memorystore-redis-python
+  owner: googleapis
+  pullRequest:
+    branch: .*
+    commentControl: COMMENTS_ENABLED_FOR_EXTERNAL_CONTRIBUTORS_ONLY
+ignoredFiles:
+  - docs/**
+  - .kokoro/**
+  - .github/**
+  - "*.md"
+substitutions:
+  _VERSION: "3.8"
+  _WORKER_POOL: ""
+  _REDIS_URL: ""
+```
+
+Use `gcloud builds triggers import --source=trigger.yaml` create triggers via the command line
+
+#### Project Setup
+
+1. Create an Memorystore for Redis instance
+1. Create a Cloud Build private worker pool
+1. Setup Cloud Build triggers (above)
+
+#### Run tests with Cloud Build
+
+* Run integration test:
+
+    ```bash
+    gcloud builds submit --config integration.cloudbuild.yaml --region us-central1 --substitutions=_WORKER_POOL="path-to-worker-pool",_REDIS_URL="redis://..."
+    ```
+
+#### Trigger
+
+To run Cloud Build tests on GitHub from external contributors, ie RenovateBot, comment: `/gcbrun`.
