-Command Line Interface (CLI) and Rust crates for the [SpatioTemporal Asset Catalog (STAC)](https://stacspec.org/) specification.
+Welcome to the home of STAC and Rust.
+We're happy you're here.
+
+## What is stac-rs?
+
+**stac-rs** is a [Github repository](https://github.com/stac-utils/stac-rs) that holds the code for several Rust [crates](https://doc.rust-lang.org/book/ch07-01-packages-and-crates.html) that can be used to create, search for, and otherwise work with [STAC](https://stacspec.org).
+
+## What is stacrs?
+
+**stacrs** (notice the lack of a hyphen) is a Python [package](https://pypi.org/project/stacrs/) that provides a simple API for interacting with STAC.
+**stacrs** uses the Rust code in **stac-rs** under the hood.
+
+```python
+import stacrs
+
+items = stacrs.search("s3://bucket/items.parquet", ...)
+```
+
+Check out the [stacrs docs](https://stac-utils.github.io/stacrs) for more.
+
+## Why are the names so confusing?
+
+Because [@gadomski](https://github.com/gadomski/), who built and maintains these tools, is really bad at naming stuff.
+
+## Why are stac-rs and stacrs in two separate repos?
+
+Couple of reasons:
+
+1. **stac-rs** is intended to be useful on its own.
+   It's not just the engine for some Python bindings.
+2. Care-and-feeding for Python wheels built from Rust is a bit finicky.
+   By moving **stacrs** to its own repo, we're able to separate the concerns of keeping a good, clean Rust core, and building Python wheels.
+   Not everyone agrees with this strategy, but here we are.
