+# Lightweight printf stdio manager
+
+<h3>Read first: <a href="http://docs.majerle.eu/projects/lwprintf/">Documentation</a></h3>
+
+## Features
+
+* Written in C (C11), compatible with ``size_t`` and ``uintmax_t`` types for some specifiers
+* Implements output functions compatible with ``printf``, ``vprintf``, ``snprintf``, ``sprintf`` and ``vsnprintf``
+* Low-memory footprint, suitable for embedded systems
+* Reentrant access to all API functions
+* Operating-system ready
+* Requires single output function to be implemented by user for ``printf``-like API calls
+* With optional functions for operating systems to protect multiple threads printing to the same output stream
+* Allows multiple output stream functions (unlike standard ``printf`` which supports only one) to separate parts of application
+* Added additional specifiers vs original features
+* User friendly MIT license
