 - SSH key added to [[forgejo|Forgejo]] (https://forge.ops.eblu.me)
-- `tea` CLI installed for PR creation

+
+## Tooling Setup
+
+The repo includes a `Brewfile` and `mise.toml` for easy setup, but these are optional - install the tools however you prefer.
+
+### Required Tools
+
+- `tea` - Gitea/Forgejo CLI for creating PRs
+- `argocd` - ArgoCD CLI for deployments
+- `pre-commit` - Git hooks for validation
+
+### Using Brewfile (Optional)
+
+```bash
+brew bundle  # installs tea, argocd, mise, etc.
+```
+
+### Using Mise (Optional)
+
+Mise manages language toolchains and runs tasks:
+```bash
+mise install  # installs Python, Node.js, etc. from mise.toml
+```
+
+### Pre-commit Hooks
+
+Pre-commit hooks validate changes on `git commit`:
+```bash
+pre-commit install
+pre-commit run --all-files  # verify setup
+```
+
+All hooks should pass on a fresh clone.
