+Introduction
+============
+
+This repository contains the libgcompat, a library providing GNU libc (glibc)
+compatibility for Linux computers using the musl libc.
+
+
+
+
+Code style
+==========
+
+Contributions are expected to maintain a consistent code style.  This ensures
+readable and future maintainability, since all the code will look and feel the
+same.  A few key notes about the C style used in this repository:
+
+
+Include comments
+````````````````
+
+When using the ``#include`` preprocessor directive, add a comment next to it
+detailing the interfaces used from that header.  For example:
+
+```
+#include <stdlib.h>     // getenv
+```
+
+
+Tabs
+````
+
+Hard tabs (\t) are used, and are 8 spaces.  Where brace alignment is required,
+tabs are used to the nearest eighth space, followed by the requisite number of
+spaces.
+
+
+Braces
+``````
+
+**Always** use braces for blocks like ``if``, ``while``, ``for``, even if the
+block only contains a single statement.  This is to ensure that more complex
+decision trees do not have accidental side-effects.
+
+
