 ## Workflow
 
-### Step 1: Push to master
-Deployment is automatic on push to `master`. To trigger manually:
+### Step 1: Verify build locally
+Run type-check + production build to catch errors before pushing:
+```bash
+npm run build
+```
+If build fails, fix errors first — don't push broken code.
+
+### Step 2: Commit and push
+Commit pending changes and push to `master` to trigger the deploy workflow:
+```bash
+git add <changed-files>
+git commit -m "feat: <description>"
+git push origin master
+```
+If there are no pending changes but user wants to redeploy, trigger manually:
 ```bash
 gh workflow run deploy-pages.yml
 ```
 
-### Step 2: Monitor deployment
+### Step 3: Monitor deployment
 Watch the workflow run:
 ```bash
 gh run list --workflow=deploy-pages.yml --limit 1
 gh run watch <run-id> --exit-status
 ```

 - Note: GitHub Pages CDN may take 1-2 minutes to update
 
-### Step 4: First deploy only
+### Step 5: First deploy only
 If this is the first deployment, configure Pages via API:
 ```bash
 gh api repos/{owner}/{repo}/pages -X PUT -f build_type="workflow"
