-...is what I **would** write here, but this is still an extremely early version of Lönn, and there isn't really any useable map-editing functionality in it yet, although it should come fairly soon. For now, it's just a very fast map viewer. For actually editing maps, continue using [Ahorn][ahorn] for now, but feel free to play around with Lönn!
+Lönn is a visual level maker and editor for the game Celeste. It allows editing map binaries, creating new ones, adding rooms, and filling the rooms with anything your heart desires (as long as what your heart desires is possible within the realms of the game).
+The generated map binaries can be loaded in the stock game or using [Everest](https://everestapi.github.io/), although the use of Everest is highly recommended. For use without Everest, you can replace a map in `Content/Maps` (remember backups), otherwise, you can place it in `Mods/<yourmodname>/Maps` with Everest and use the custom chapter loading (refer to the [Mod Structure guide](https://github.com/EverestAPI/Resources/wiki/Mod-Structure)).
 
 The program is still in an early state, many things are still missing and it is under active development. If you spot something that is missing, it will most likely be added some time in the near future. If you spot a bug or the program crashes, please report it.
 
 Lönn is a successor to [Ahorn][ahorn], a visual level maker based on [Maple][maple]. If you want to be able to generate and edit maps using code, give Maple a try.

-**When will I be able to place [entity/decal/trigger/other thing in celeste]?**
+**When will I be able to do [thing you can do in Ahorn]?**
 
-Whenever we add it. Celeste has a lot of things which support for has to be individually added. This takes time, so please be patient. However, if more people complain about the lack of a particular thing, we might add it sooner. For a (currently) more complete set of features, consider using [Ahorn][ahorn] for now.

-**What will you do once the official map maker is out?**

-Whenever that happens, we might just continue like before; it might well be that the official editor will not be quite as powerful as Lönn tries to be. It might not ever exist. We'll see.
