 # Flux GitHub Action
 
-To install the latest Flux CLI on Linux, macOS or Windows GitHub runners:
+Usage:
 
 ```yaml
-steps:
-  - name: Setup Flux CLI
-    uses: fluxcd/flux2/action@main
-    with:
-      version: 'latest'
-  - name: Run Flux CLI
-    run: flux version --client
+    steps:
+      - name: Setup Flux CLI
+        uses: fluxcd/flux2/action@main
+      - name: Run Flux commands
+        run: flux -v
 ```
 
-The Flux GitHub Action can be used to automate various tasks in CI, such as:
+The latest stable version of the `flux` binary is downloaded from
+GitHub [releases](https://github.com/fluxcd/flux2/releases)
+and placed at `/usr/local/bin/flux`.
 
-- [Automate Flux upgrades on clusters via Pull Requests](https://fluxcd.io/flux/flux-gh-action/#automate-flux-updates)
-- [Push Kubernetes manifests to container registries](https://fluxcd.io/flux/flux-gh-action/#push-kubernetes-manifests-to-container-registries)
-- [Run end-to-end testing with Flux and Kubernetes Kind](https://fluxcd.io/flux/flux-gh-action/#end-to-end-testing)
+Note that this action can only be used on GitHub **Linux** runners.
+You can change the arch (defaults to `amd64`) with:
 
-For more information, please see the [Flux GitHub Action documentation](/flux/flux-gh-action.md).
+```yaml
+    steps:
+      - name: Setup Flux CLI
+        uses: fluxcd/flux2/action@main
+        with:
+          arch: arm64 # can be amd64, arm64 or arm
+```
 
+You can download a specific version with:
+
+```yaml
+    steps:
+      - name: Setup Flux CLI
+        uses: fluxcd/flux2/action@main
+        with:
+          version: 0.32.0
+```
+
+You can also authenticate against the GitHub API using GitHub Actions' `GITHUB_TOKEN` secret.
+
+For more information, please [read about the GitHub token secret](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#about-the-github_token-secret).
+
+```yaml
+    steps:
+      - name: Setup Flux CLI
+        uses: fluxcd/flux2/action@main
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+This is useful if you are seeing failures on shared runners, those failures are usually API limits being hit.
+
+### Automate Flux updates

+### Push and sign Kubernetes manifests to container registries
+
+Example workflow for publishing Kubernetes manifests bundled as OCI artifacts
+which are signed with Cosign and GitHub OIDC:
