 3. The preferred __image size__ is `800x600`. Please scale all images down to save bandwidth. Try to keep an aspect ratio of 4:3 for the first image, or it will be cropped on the recipe overview page! All other images will be shown unmodified in whatever aspect ratio is provided (individual recipe page)
 
-4. __AppCache__ is disabled during development. However, you can pass `-f ENABLE_APPCACHE` to any `lektor` command to enable it. The makefile does this by default for the `build` target.
 
 Also, see [Lektor docs](https://www.getlektor.com/docs/) and [jinja2 template](https://jinja.palletsprojects.com/en/2.10.x/templates/) documentation.
