+## Selective Redeploy
+When changes are pushed to this repo only the affected services are redeployed.
+This is effected by a combination of GitHub Actions and Ansible Playbooks as follows:
+
+* each Service has a dedicated GitHub Action "deploy" file, e.g. [deploy.pygeoapi_test.yml](.github/workflows/deploy.pygeoapi_test.yml)
+* the GitHub Action "deploy" file contains a trigger for a `push` with a `paths` constraint, in this example:
+```  
+    on:
+      push:
+        paths:
+          - 'services/pygeoapi_test/**'
+```   
+* the GH Action then calls the Ansible Playbook [deploy.yml](ansible/deploy.yml) with a `--tags` option related to the Service, e.g. `--tags pygeoapi_test`
+* the [deploy.yml](ansible/deploy.yml) will always update the GH repo on the server VM via the `pre_tasks`
+* the Ansible task indicated by the `tags` is then executed
