+
+👷 **Work In Progress** 🚧 Starplot is still very much a work in progress, and under active development. We try to follow [semantic versioning](https://semver.org/), which means that [_anything_ can change between versions before `1.0.0`](https://semver.org/#spec-item-4).
+
+However, the Starplot API becomes more stable with each new version. We anticipate that version `1.0.0` is still at least a year away. The best way to help us get there faster is to [join as a contributor](https://github.com/steveberardi/starplot/blob/main/CONTRIBUTING.md) 😃 help is wanted and very much appreciated!
