# SOL Enhanced
An enhanced version of the SkolaOnLine (SOL) online school system.
It aims to provide more readable data than the web version and
remove some of the annoyances of the mobile app.
Insiration was taken from [@JakubAndrysek](https://github.com/JakubAndrysek)'s [skola-online-stahovani-znamek](https://github.com/JakubAndrysek/skola-online-stahovani-znamek) project.
## Still in development!
#### It is not ready yet.
