-This project decompresses lzo compressed file systems and can use the faster, native (C-based) lzo implementation when
-installed, instead of the slower pure Python implementation provided by :doc:`/projects/dissect.util/index`. To use

+This project supports file systems with LZO compression. It can use either a fast Rust implementation, or a slow pure Python implementation. Both implementations are provided by :doc:`/projects/dissect.util/index`, and the faster implementation will automatically be used if available.
+Pre-build wheels are available for most common platforms. In the rare case that a pre-build wheel is not available, please refer to :doc:`/projects/dissect.util/index` for build instructions.

+In the rare case that a pre-build wheel is not available, the pure Python implementation will automatically be used instead.
+If you wish to build your own wheel in the case a pre-build one is not available for your platform, you can do so by running the following command:
 
 .. code-block:: console
 
-    $ pip install "dissect.util[lz4,lzo]"

+Note that you'll need to bring your own Rust toolchain for the target platform you wish to build a wheel for. For example, using [rustup](https://rustup.rs).
