+### Automated setup
+
+The easiest way to configure a project is to run the setup CLI, which will install all other required devDependencies and configure the project automatically:
+
+```sh
+yarn sofie-code-standard-preset-setup
+```
+
+This will:
+
+1. Set the `prettier` field in `package.json` to use the preset's config
+2. Add `lint`, `lint:eslint`, `lint:prettier`, `lint:fix`, `license-validate` and `prepare` scripts
+3. Set `lint-staged` config
+4. Create `eslint.config.mjs` if missing
+5. Copy `.editorconfig` from the preset
+6. Create `.husky/pre-commit` if missing
+7. Install required devDependencies via `yarn add --dev` (`@eslint/js`, `eslint`, `husky`, `lint-staged`, `prettier`, `typescript`)
+
+If any of the above items are already configured to a different value, they will be skipped with a warning. Pass `--force` to overwrite existing values:
+
+```sh
+yarn sofie-code-standard-preset-setup --force
+```
+
+After running, review and commit the changes, then follow the manual steps below to add any project-specific configuration.
