 A safety oriented and memory safe implementation of sudo and su written in Rust.
 
-## ⚠️ WARNING
+## Status of this project
 
-**Sudo-rs is currently under active development and is not suited for any
-production environment. Using sudo-rs is only recommended for development and
-testing purposes, but you should expect any system that has sudo-rs installed to
-break easily and to not be secure.**
+Sudo-rs is being developed further; features you might expect form original sudo
+may still be unimplemented or not planned. If there is an important one you need,
+please request it using the issue tracker. If you encounter any usability bugs,
+also please report them on the [issue tracker](https://github.com/memorysafety/sudo-rs/issues).
+Suspected vulnerabilities can be reported on our [security page](https://github.com/memorysafety/sudo-rs/security).
 
-Sudo-rs currently only supports Linux-based operating systems, even if it compiles
-on a different system, it will not run properly.
+An audit of sudo-rs will take place in September 2023, the next stable release will
+incorporate its results.
 
-## Quick start
+Sudo-rs currently is targeted for Linux-based operating systems only; Linux kernel 5.9
