-## Development status
+## Features
 
-This project was originally developed in 2019 while I worked at Otovo.
-Eventually, it was never used there, and at the end of 2023, I got the project
-back under my control.
+### Enhetsregistret
 
-I intend to brush the project up with modern project tooling and typing hints,
-making it a good foundation to build upon, and will release a 1.0 release as
-soon as that is done.
+The `brreg.enhetsregisteret` part of this library wraps the open
+[Enhetsregistret API](https://data.brreg.no/enhetsregisteret/api/docs/index.html).
 
+This is a list of all features this library could implement on top of this API.
 However, I will not attempt to make the project cover all parts of
-Brønnøysundregisterene's API. I am open to requests, so that time is spent
-on the parts of the API that there is an actual demand for.
