+# vxLibc
+
+This is a wrapper around the
+[fxlibc](https://gitea.planet-casio.com/Vhex-Kernel-Core/fxlibc) project
+which is the standard system C library implementation for all Casio fx
+calculators.
+
+## Installing
+
+You can use the `scripts/install.sh --help` to see manual installation of the
+project. But, since the compiler needed to build the `vxOpenLibm` is
+`sh-elf-vhex` which automatically installs this project, you theoretically do
+not need to do so.
+
+## README and Licensing
+
+See the original
+[REAME file](https://gitea.planet-casio.com/Vhex-Kernel-Core/fxlibc/src/branch/master/README.md)
+of the `fxlibc` project for further information.
+Note that `fxlibc` uses the `CC0 1.0 Universal License`, see
+[LICENSE](https://gitea.planet-casio.com/Vhex-Kernel-Core/fxlibc/src/branch/master/LICENSE)
+
+## Special thanks
+
+A big thanks to
+[Lephenixnoir](https://silent-tower.net/projects/) who ported most of the
+standard!
