-# SharedInbox CI Runner
-
-This directory contains the configuration for a self-hosted Codeberg (Forgejo) Actions runner. 
-
-## Strategy: "Thin CI, Heavy Taskfile"
-We use a self-hosted runner to bypass the resource limits of hosted CI. The CI workflow is a thin wrapper that invokes `nix develop --command task check`. This ensures that CI environments are identical to local development environments.
-
-## Prerequisites
-- Docker and Docker Compose installed.
-- Systemd (for persistence).
-- A registration token from Codeberg (Settings > Actions > Runners).
-- A `.env` file in the project root containing `CODEBERG_CI_RUNNER_TOKEN`.
-
-## Installation & Setup
-
-Run these commands as a user with `sudo` to install the runner on your laptop or VPS:
-
-```bash
-# 1. Create the system directory
-sudo mkdir -p /opt/sharedinbox-runner
-
-# 2. Copy the runner configuration and your .env file
-# (Run this from the root of your local sharedinbox3 project)
-sudo cp -r sharedinbox-runner /opt/sharedinbox-runner/
-sudo cp .env /opt/sharedinbox-runner/
-
-# 3. Install the systemd service
-sudo cp /opt/sharedinbox-runner/sharedinbox-runner/sharedinbox-runner.service /etc/systemd/system/
-
-# 4. Reload systemd and start the service
-sudo systemctl daemon-reload
-sudo systemctl enable --now sharedinbox-runner.service
-```
-
-## Management
-- **Check status:** `systemctl status sharedinbox-runner.service`
-- **View logs:** `journalctl -u sharedinbox-runner.service -f`
-- **Restart:** `sudo systemctl restart sharedinbox-runner.service`
-- **Stop:** `sudo systemctl stop sharedinbox-runner.service`
