+  - An `ansible` user account with passwordless sudo (run the

+To develop on your computer:
+  - A Python virtualenv with the [requirements](./requirements.txt) installed
+  - Recommended: the [`just`][just-manual] command runner, to simplify running commands
+  - Recommended: Visual Studio Code with the [`Ansible` extension][ansible-vscode-extension] (you should be prompted to install it when opening the project)
+
 ## Usage
 
+A `justfile` is provided, to help you run the most common commands. Once you have [installed just][just-installation], you can run the following:
+  - `just` (with no arguments): list all recipes/commands available
+  - `just playbook-deploy-infra`: run the playbook (you can add any argument and they will be passed to the underlying `ansible-playbook` command)
+  - `just lint`: run [ansible-lint][ansible-lint] to check the playbooks and roles for errors and bad practices
+  - `just todo`: search all files for `# TODO` and `# noqa` comments (they silence linter errors)
+  - `just vault <username>`: login to Vault using the `userpass` method
+  - `just venv`: create a local virtualenv using the currently available Python (in [`.venv`](./venv)) and install dependencies using `pip`
+  - `just cmdb`: generate an HTML overview of all hosts in the inventory with information gathered by Ansible, including variables (using [`ansible-cmdb`][ansible-cmdb])
+  - ...and more, see `just` for the updated list
+
+If you want to run a playbook manually, you will need to:
 1. Export the Vault URL: `export VAULT_ADDR=https://<vault URL>`
 2. Login to Vault: `vault login -method=userpass username=<username>` (you can use any other method)
 3. Retrieve the SSH private key from Vault and save it as `id_ed25519_ansible`
-4. Execute a playbook: `ansible-playbook --inventory hosts deploy-server.yml`

+
+## Continuous Integration (CI)
+
+A [GitHub Actions workflow](./.github/workflows/test.yml) is run on all push and pull requests to check any alerts from [`ansible-lint`][ansible-lint].
