 ## Updating
 
+When adding/removing packages from `package.json`, the corresponding
+`package-lock.json` needs to be updated. Use `nix/update-lockfile` for
+this.
+
+When ignoring semver is desired, use:
+
 ```sh
 npm-check-updates -u
-rm node_modules # Yeah, npm gets confused if it can't write here
-npm install --package-lock-only
-rm -rf node_modules
-direnv reload
 ```
