+## Packaging for NPM
+
+Scott, this is here for you to remember how to do this 🙃
+
+Although I detailed this in
+[Making npm Packages with SvelteKit](https://scottspence.com/posts/making-npm-packages-with-sveltekit)

+the instructions are never there! 😅
+
+**Publish the project to NPM**
+
+```bash
+# authenticate with npm
+npm login
+# bump version with npm
+npm version 0.0.2
+# package with sveltkit
+pnpm run package
+# publish from package directory
+cd package
+npm publish
