* fix(docker): do not add `shielded-scan` as part of `TEST_FEATURES`

* chore: remove misleading comment

* feat(docker): add `docker-compose` file to run CI locally

* fix(docs): do not remove previous sections until we have a substitute for users

* fix(docs): revert some changes

 The easiest way to run Zebra is using [Docker](https://docs.docker.com/get-docker/).

+We've embraced Docker in Zebra for most of the solution lifecycle, from development environments to CI (in our pipelines), and deployment to end users. We recommend using `docker-compose` over plain `docker` CLI, especially for more advanced use-cases like running CI locally, as it provides a more convenient and powerful way to manage multi-container Docker applications.

-### Build time arguments
+### CI/CD Local Testing
+
+To run CI tests locally, which mimics the testing done in our CI pipelines on GitHub Actions, use the `docker-compose.test.yml` file. This setup allows for a consistent testing environment both locally and in CI.
+
+#### Running Tests Locally
+
+1. **Setting Environment Variables**:
+   - Modify the `test.env` file to set the desired test configurations.
+   - For running all tests, set `RUN_ALL_TESTS=1` in `test.env`.
+
+2. **Starting the Test Environment**:
+   - Use Docker Compose to start the testing environment:
+
+     ```shell
+     docker-compose -f docker/docker-compose.test.yml up
+     ```
+
+   - This will start the Docker container and run the tests based on `test.env` settings.
+
+3. **Viewing Test Output**:
+   - The test results and logs will be displayed in the terminal.
+
+4. **Stopping the Environment**:
+   - Once testing is complete, stop the environment using:
+
+     ```shell
+     docker-compose -f docker/docker-compose.test.yml down
+     ```
+
+This approach ensures you can run the same tests locally that are run in CI, providing a robust way to validate changes before pushing to the repository.

 ## Registries
 
 The images built by the Zebra team are all publicly hosted. Old image versions meant to be used by our [CI pipeline](https://github.com/ZcashFoundation/zebra/blob/main/.github/workflows/ci-integration-tests-gcp.yml) (`zebrad-test`, `lighwalletd`) might be deleted on a scheduled basis.
