 ### Install
 
+**1. Configure your `.npmrc` to use the GitLab Package Registry:**
+
 ```sh
-git clone <repo-url> && cd codewalk-district
+# Project-level .npmrc (recommended) — or add to ~/.npmrc for global config
+@carealytix:registry=https://gitlab.com/api/v4/projects/<PROJECT_ID>/packages/npm/
+//gitlab.com/api/v4/projects/<PROJECT_ID>/packages/npm/:_authToken=<YOUR_TOKEN>
+```
+
+Replace `<PROJECT_ID>` with the GitLab project ID and `<YOUR_TOKEN>` with a personal access token (scope: `read_api`) or deploy token.
+
+**2. Install globally:**
+
+```sh
+npm install -g @carealytix/codewalkers
+```
+
+This makes the `cw` CLI available globally.
+
+**Alternative: Install from source**
+
+```sh
+git clone git@gitlab.com:carealytix/tools/codewalkers.git && cd codewalkers
 npm install
 npm run build
 npm link
