+# h3ron
+
+[h3](https://h3geo.org) library for [rust](https://rustlang.org)
+
+This repository consists of multiple crates:
+
+* [h3ron-h3-sys](./h3ron-h3-sys): bindgen-generated bindings for statically linked libh3.
+* [h3ron](./h3ron): high level rust API including collections for selected parts of H3.
+* [h3ron-ndarray](./h3ron-ndarray): Integration with the [ndarray](https://github.com/rust-ndarray/ndarray) crate to generate H3 data from raster data (using [gdal](https://github.com/georust/gdal), ...)
+
+## Why this name?
+
+Well, coming up with a good name for a project while avoiding naming conflicts is hard. On the other hand are animal-based names always pretty easy to remember.
+
+How to pronounce it? I got no idea - probably like the [heron bird family](https://en.wikipedia.org/wiki/Heron).
