 # [WIP] sqlxgentools
 
-Tools to generate SQL migrations and Rust SQLx repositories code from models structs to use with a SQLite database.
+Little tool to generate SQLite migrations files and Rust SQLx repositories code, all from models structs.
 
-Will be used in [minauthator](https://forge.lefuturiste.fr/mbess/minauthator).
+Still very much work in progress, but it can be already used in your next Rust app if you don't mind some limitations like the lack of incremental migrations and little quirks here and there.
