 ## Deployment
 
 This is mostly for me when I revisit this godforsaken project in 7 months having forgotten everything :P
 
-This repository has a [publish.yml](.github/workflows/publish.yml) action which automatically builds
-the [Dockerfile](Dockerfile) and pushes
-to [Docker Hub](https://hub.docker.com/repository/docker/sgoudham/website/general) with the latest updates. This image
-is then automatically retrieved by [Watchtower](https://containrrr.dev/watchtower/) on my server which automatically
-replaces the production docker container, therefore deploying the new updates to production. (In the future, I may
-switch this workflow to only use [Portainer](https://www.portainer.io/).)
+This repository has 2 workflow files:
 
-### Manual Commands
-
-```shell
-docker tag website:latest sgoudham/website:latest
-docker push sgoudham/website:latest
-```
+- **[preview.yml](.github/workflows/preview.yml)** - This workflow is triggered on every pushed commit to the main branch.
+  - The website is built and deployed to docker hub as `sgoudham/website:preview`
+  - My server automatically pulls the latest image from the `preview` tag and deploys it under `https://preview.goudham.com`.
+- **[release.yml](.github/workflows/release.yml)** - This workflow is triggered on any pushed tag.
+  - The website is built and deployed to docker hub as `sgoudham/website:<tag>`.
+  - My server automatically pulls the latest tag `<tag>` and deploys it under `https://goudham.com`.
