+relibc is a portable POSIX C standard library written in Rust and is under heavy development.

 The motivation for this project is twofold: Reduce issues that the Redox developers were having with [newlib](https://sourceware.org/newlib/), and create a safer alternative to a C standard library written in C. It is mainly designed to be used under Redox, as an alternative to newlib, but it also supports Linux system calls via the [sc](https://crates.io/crates/sc) crate.

+## Download the sources
+
+To download the relibc sources run the following command:
+
+```sh
+git clone --recursive https://gitlab.redox-os.org/redox-os/relibc
+```
+
+## Build Instructions
+
+To build relibc out of the Redox build system, do the following steps:
+
+### Dependencies
+
+- Install `cbindgen`
+
+```sh
+cargo install cbindgen
+```
+
+#### Install the `expect` tool
+
+- Debian, Ubuntu and PopOS:
+
+```sh
+sudo apt install expect
+```
+
+- Fedora:
+
+```sh
+sudo dnf install expect
+```
+
+- Arch Linux:
+
+```sh
+sudo pacman -S expect
+```
+
+### Build Relibc
+
+To build the relibc library objects, run the following command:
+
+```sh
+make all
+```
+
+- Clean old library objects and tests
+
+```sh
+make clean
+```

+If you need to rebuild `relibc` for testing a Cookbook recipe, run:
+
+```sh
+touch relibc
+make prefix r.recipe-name
+```
+
+Touching (changing the "last modified time" of) the `relibc` folder is needed to trigger recompilation for `make prefix`. Replace `recipe-name` with your desired recipe name.
+
+Note: Do not edit `relibc` inside `prefix` folder! Do your work on `relibc` folder directly inside your Redox build system instead.
+
+## Tests
+
+This section explain how to build and run the tests.
+
+### Build
+
+To build the tests run `make all` on the `tests` folder, it will store the executables at `tests/bins_static`
+
+If you did changes to your tests, run `make clean all` to rebuild the executables.
+
+### Redox OS Testing
+
+To test on Redox do the following steps:
+
+- Add the `relibc-tests` recipe on your filesystem configuration at `config/your-cpu/your-config.toml` (generally `desktop.toml`)
+- Run the following commands to rebuild relibc with your changes, update the `relibc-tests` recipe and update your QEMU image:
+
+```sh
+touch relibc
+```
+
+```sh
+make prefix cr.relibc-tests image
+```
+
+- Run the tests
+
+```sh
+/usr/share/relibc-tests/bins_static/test-name

+
+### Linux Testing
+
+Run `make test` on the relibc directory.
