## Before you start

[Connect your git host](https://usefiretower.com/docs/git). Have a setup command for your project and any environment variables it needs.

Screenshots show the desktop app with sample data.

## 1\. Open the repository

Open **Repositories → All repositories**. Find the repository and select its row to expand the settings.

## 2\. Save the setup command

Enter the command under **Setup script**. It runs after checkout and before the agent starts. For example: `pnpm install --frozen-lockfile`.

If the project needs an environment file, enter a relative path such as `.env`. Select **Save**.

## 4\. Review the saved configuration

The saved variable names appear under **Environment**; their values stay hidden. Keep the environment file out of git.

Start a new workspace to use these settings. If setup fails, check the setup output, then correct the command or missing tools on the worker.
