 ### Development
 
-Run at least once: `make fetch` to query servers. This can take around 5 minutes.
+Run at least once: `make fetch` to query servers. This takes around 15 seconds thanks to the coroutine implementation.
 
 Run when developing: `make dev` to watch for changes & serve HTML locally in browser.
 
-Symlink the commit hooks provided in [`etc/hooks`](etc/hooks/) to `.git/hooks/<hook>` to run a full test cycle when committing to main.
-
 See [`Makefile`](Makefile) for more details.
 
+Recommended:
+
+- Add the [default include paths](.phpenv) (`.`, `php`) to your PHP intellisense.
+
+- Symlink the commit hooks provided in [`etc/hooks`](etc/hooks/) to `.git/hooks/<hook>` to run a full test cycle when committing to main.
+
+
 ### Running your own copy
 
 - point your webserver at the [`output`](output/) folder
