 uutils is an attempt at writing universal (as in cross-platform) CLI
-utilities in [Rust](http://www.rust-lang.org). This repository is intended to
-aggregate GNU coreutils rewrites.
+utilities in [Rust](http://www.rust-lang.org).
+
+To install it:
+
+```
+$ cargo install coreutils
+$ ~/.cargo/bin/coreutils
+```
 
 ## Why?
 
-Many GNU, Linux and other utilities are useful, and obviously
-[some](http://gnuwin32.sourceforge.net) [effort](http://unxutils.sourceforge.net)
-has been spent in the past to port them to Windows. However, those projects
-are written in platform-specific C, a language considered unsafe compared to Rust, and
-have other issues.
+uutils aims to work on as many platforms as possible, to be able to use the
+same utils on Linux, Mac, Windows and other platforms. This ensures, for
+example, that scripts can be easily transferred between platforms. Rust was
+chosen not only because it is fast and safe, but is also excellent for
+writing cross-platform code.
 
-Rust provides a good, platform-agnostic way of writing systems utilities that are easy
-to compile anywhere, and this is as good a way as any to try and learn it.
+## Documentation
+uutils has both user and developer documentation available:
 
+- [User Manual](https://uutils.github.io/coreutils-docs/user/)
+- [Developer Documentation](https://uutils.github.io/coreutils-docs/dev/coreutils/)
+
+Both can also be generated locally, the instructions for that can be found in the
+[coreutils docs](https://github.com/uutils/coreutils-docs) repository.

+<!-- ANCHOR: installation (this mark is needed for mdbook) -->
 ## Requirements
 
 * Rust (`cargo`, `rustc`)
-* GNU Make (required to build documentation)
-* [Sphinx](http://www.sphinx-doc.org/) (for documentation)
-* gzip (for installing documentation)
+* GNU Make (optional)
 
 ### Rust Version
 
 uutils follows Rust's release channels and is tested against stable, beta and nightly.

-## Contribute
+### Improving the GNU compatibility
+
+The Python script `./util/remaining-gnu-error.py` shows the list of failing tests in the CI.
+
+To improve the GNU compatibility, the following process is recommended:
+
+1. Identify a test (the smaller, the better) on a program that you understand or is easy to understand. You can use the `./util/remaining-gnu-error.py` script to help with this decision.
+1. Build both the GNU and Rust coreutils using: `bash util/build-gnu.sh`
+1. Run the test with `bash util/run-gnu-test.sh <your test>`
+1. Start to modify `<your test>` to understand what is wrong. Examples:
+    1. Add `set -v` to have the bash verbose mode
+    1. Add `echo $?` where needed
+    1. Bump the content of the output (ex: `cat err`)
+    1. ...
+1. Or, if the test is simple, extract the relevant information to create a new test case running both GNU & Rust implementation
+1. Start to modify the Rust implementation to match the expected behavior
+1. Add a test to make sure that we don't regress (our test suite is super quick)

+uutils is an attempt at writing universal (as in cross-platform) CLI
+utilities in [Rust](https://www.rust-lang.org). It is available for
+Linux, Windows, Mac and other platforms.
+
+The API reference for `uucore`, the library of functions shared between
+various utils, is hosted at at
+[docs.rs](https://docs.rs/uucore/latest/uucore/).

+#  Multi-call binary
+uutils includes a multi-call binary from which the utils can be invoked. This
+reduces the binary size of the binary and can be useful for portability.
+
+The first argument of the multi-call binary is the util to run, after which
+the regular arguments to the util can be passed.
+
+```shell
+coreutils [util] [util options]
+```
+
+The `--help` flag will print a list of available utils.
