+
+# Build New Icons
+
+Use this workflow after new SVG icons are added to `src/icons/`.
+
+## Workflow
+
+1. Compare `src/icons/*.svg` with the entries in `src/template/metadata.json`.
+2. Identify and list every icon that does not yet have metadata. If the user supplied icon names, verify them against this comparison rather than assuming the list is complete.
+3. Read `src/template/mapping.json` and allocate the next unused decimal codepoint to each new icon. Add each icon as the primary name under its codepoint and keep the codepoints in ascending order.
+4. Add an entry to `src/template/metadata.json` for every new icon:
+
+   ```json
+   "<icon-name>": {
+     "tags": ["<keyword1>", "<keyword2>"],
+     "category": "<category>",
+     "description": "<Short description of the icon>"
+   }
+   ```
+
+   - Add four to eight search tags that describe the icon's appearance and likely uses.
+   - Use the best-fitting category already present in the file, such as `action`, `navigation`, `debug`, `file`, `user`, `git`, `layout`, `editor`, `symbol`, `status`, `media`, `device`, or `misc`.
+   - Write a concise, one-line description.
+   - Keep entries sorted alphabetically by icon name.
+
+5. Run `npm run build` from the `vscode-codicons` repository root and wait for it to finish.
+6. If the build fails, diagnose and fix the failure before continuing.
+7. Verify that every new icon remains a primary name under its assigned codepoint in `src/template/mapping.json`.
+8. Run `node scripts/check-metadata.js`.
+9. Confirm that the metadata check reports no missing or orphaned entries.
+10. Summarize:
+    - The new icon names.
+    - Their codepoints from `src/template/mapping.json`.
+    - Their entries from `src/template/metadata.json`.
