+## Act Runner Installer
+
+Simple installer to fetch and install the latest `gitea/act_runner` release for your Linux machine.
+
+### Quick start
+
+Run the installer directly:
+
+```bash
+curl -fSSL https://<url>/install.sh | bash
+```
+
+If your environment requires elevated permissions to write to `/usr/local/bin`, run with sudo:
+
+```bash
+curl -fSSL https://<url>/install.sh | sudo bash
+```
+
+### What it does
+
+- Detects your CPU architecture
+- Fetches the latest `act_runner` release info
+- Downloads the appropriate Linux binary
+- Installs it to `/usr/local/bin/act_runner` and makes it executable
+
+### Requirements
+
+- Linux
+- `curl`, `jq`, `wget`, `unxz`, `sha256sum`
+
+### Notes
+
+- The script will update an existing installation if a newer version is available.
+- You may need network access to `gitea.com` to retrieve release metadata.
+
+### Uninstall
+
+```bash
+sudo rm -f /usr/local/bin/act_runner
+```
