 This is a list of the crates that make up Fornjot, along with a short description for each, starting with the most basic ones and leading up to the high-level ones:
 
-- [`fj-math`]: Math primitives used by the rest of the Fornjot ecosystem.
+- `fj` (not published yet; crate on `crates.io` is not the same library): All-in-one API that re-exports all of the following crates.
+- [`fj-math`]: Math primitives used by the rest of Fornjot.
 - [`fj-interop`]: Basic types that allow other crates to interoperate, without depending on each other.
-- [`fj-kernel`]: CAD kernel of Fornjot. Defines geometric and topological primitives, and algorithms that operate on those primitives.
+- `fj-core` (not published yet): Core primitives and code operating on those primitives.
 - [`fj-export`]: Exports Fornjot models to external data formats.
 - [`fj-viewer`]: Displays Fornjot models.
+- `fj-window` (not published yet; crate on `crates.io` is not the same library): Simple windowing abstraction for use with `fj-viewer`.
