+Project status & release process
+--------------------------------
+
+This library is still under development.
+
+The current releases are numbered `0.x.y`. When a non-breaking change is introduced (adding new methods, optimizing existing code, etc.), `y` is incremented.
+
+**When a breaking change is introduced, a new `0.x` version cycle is always started.**
+
+It is therefore safe to lock your project to a given release cycle, such as `0.1.*`.
+
+If you need to upgrade to a newer release cycle, check the [release history](https://github.com/brick/geo/releases) for a list of changes introduced by each further `0.x.0` version.
