+The purpose of this repository is twofold:
+
+* Provide Rust packages for interacting with BeeGFS.
+* Provide BeeGFS-related software written in Rust, such as the BeeGFS management service.

+
+## Prerequisites
 
-3. The management can be built and run through cargo in one step:
+* If you just want to build/run the project without OS packages download and install Rust from
+  [rustup](https://rustup.rs/).
+* If you want to build packages you also need to run `make install-tools`.
+  * Note this only installs the tooling needed for a local, native build and is insufficient for
+    cross-compilation.
+
+If you are interested in contributing to the project please refer to [Getting Started with Rust](https://github.com/ThinkParQ/beegfs-rust/wiki/Getting-Started-with-Rust) in the project wiki.

+## Building (With or Without Packaging)
