-*Support for Python >= 3.10 should be considered experimental
-until further notice.*
+Note that while we support Python 3.10.\*, wheels for the `orjson` library are not always immediately available for all
+platforms. If you install PySTAC with the `orjson` extra, you may need to have the Rust toolchain installed (e.g. via [rustup](https://rustup.rs/)) in order to
+build the package from source.
 
 PySTAC has a single required dependency (`python-dateutil`).
 PySTAC can be installed from pip or the source repository.
