 ### Deployment pipeline
 
-- [Cloudflare Pages](https://pages.cloudflare.com) will automatically deploy staging (main branch) and per branch preview.
+- **Staging**: Each push will trigger the [Github Actions Workflow](.github/workflows/staging.yml) to build the site, upload the build artifact, and deploy on [Cloudflare Pages](https://pages.cloudflare.com). Can also be triggered manually.
+- **Production**: The [Github Actions Workflow](.github/workflows/staging.yml) can only be manually triggered to download the latest build artifact and upload to our server through SSH.

 - Zod's schema for each data table are defined in [src/models](src/models) which also contains ER Diagram and other TypeScript's interfaces.
+- Some data, such as politician ranking from external source, will be updated periodically through [scheduled Github Action](.github/workflows/update-ranking.yml) to reduce unnessesary build-time. The output JSON data is [served through Github Pages](https://wevisdemo.github.io/parliament-watch/politician-ranking.json) and can be fetch from the client-side.
