+Crevice is similar to [`glsl-layout`][glsl-layout], but supports types from many
+math crates, can generate GLSL source from structs, and explicitly initializes
+padding to remove one source of undefined behavior.
 
-Examples in this crate use cgmath, but any math crate that works with the mint
-crate will also work. Some other crates include nalgebra, ultraviolet, glam, and
-vek.
+Crevice has support for many Rust math libraries via feature flags, and most
+other math libraries by use of the mint crate. Crevice currently supports:
+
+* mint 0.5, enabled by default
+* cgmath 0.18, using the `cgmath` feature
+* nalgebra 0.29, using the `nalgebra` feature
+* glam 0.19, using the `glam` feature
+
+PRs are welcome to add or update math libraries to Crevice.
+
+If your math library is not supported, it's possible to define structs using the
+types from mint and convert your math library's types into mint types. This is
+supported by most Rust math libraries.
+
+Your math library may require you to turn on a feature flag to get mint support.
+For example, cgmath requires the "mint" feature to be enabled to allow
+conversions to and from mint types.
