+> This library is a work in progress, you can choose to use the last available version 0.3.0, or use the `main` branch that contains the next 1.0 release.
+> 1.0 will have several breacking changes, so I don't recommend you start a project using 0.3, just use the `main` branch from now, as the API is pretty much stable at this stage.
