 ### Deploy
 
-Builds the Docker image, starts the container, and registers a Pangolin resource.
+Builds the Docker image, starts the container, and registers a Pangolin resource. The branch name drives everything else: pushes to the repo's default branch deploy as `production`, all other branches deploy as previews with a slugified tag, a deterministic host port, and a `${slug}.${app-name}` subdomain.
 
     - uses: https://git.zyrrus.dev/eighty-six/node-deploy-action/deploy@v1
       with:
         app-name: my-app
-        tag: production
-        port: "3001"
-        environment: production
-        subdomain: my-app
+        branch: ${{ github.ref_name }}
 
 Inputs
 
 `app-name`
 
-Application name (used for image/container naming)
+Application name (used for image/container naming, and as the production subdomain)
 
-`tag`
+`branch`
 
-Image/container tag (e.g. `production` or a branch slug)
-
-`port`
-
-Host port to expose
+Branch name. Matches against `github.event.repository.default_branch` to decide production vs. preview. `refs/heads/` prefix is stripped.
 
 `internal-port`
 
 Port the app listens on inside the container (default `3000`)
 
-`environment`
-
-`production` or `preview`
-
-`subdomain`
-
-Subdomain for the Pangolin resource
-
 `build-args`
 
 Extra `KEY=VALUE` docker build args (space-separated)
 
-### Slug
-
-Derives a URL-safe slug and a deterministic port from a branch name. Strips `refs/heads/` so either `github.ref_name` or `github.event.ref` works.
-
-    - id: slug
-      uses: https://git.zyrrus.dev/eighty-six/node-deploy-action/slug@v1
-      with:
-        branch: ${{ github.ref_name }}
-
-Outputs: `slug`, `port`.
-
 ### Cleanup
 
-Stops the preview container and removes its Pangolin resource. Intended for `delete` branch events.
+Stops the preview container and removes its Pangolin resource. Intended for `delete` branch events — the slug is derived from the branch name internally.
