 ## Features <a name="features"></a>
 
+- Supports both 8-bit and 4-bit modes of LCD's
+- Configurable, so it should work on most devices, albeit with some tweaking
+- Read/Write the character LCD
+- Control the display using ANSI and ASCII escapes
+- Read/Write custom characters to memory and/or the LCD display (not fully implemented)
+
 ## Tools <a name="tools"></a>
 
+This project wouldn't be possible without the following great open source tools:
+
+- AVR-GCC, [AVR-libc][], and AVR-binutils which form the compiler toolchain that makes open
+  source development for AVR microcontrollers possible.
+- [avrdude][] to do in system programming of the AVR microcontrollers
+- [doxygen][] to generate documentation.
+- [Gnu Emacs][], because how else would I enter text?
+

-## Building <a name="building"></a>
+## Usage <a name="usage"></a>
+
+Clone this repository and modify lcdLibConfig.h to your needs. See the documentation for more
+details.
+
+    git clone http://git.rekahsoft.ca/lcdLib.git
+    doxygen doxygen.conf # If you want to generate offline documentation
 
 ## Issues <a name="issues"></a>
 
+- No interface is given to read/write custom characters, though it can be done manually using
+  the lower level plumbing function `writeLCDInstr`.
+- No examples of using the library are currently given but do exist in the git history. They
+  have been split out into their own repository's and soon will be re-added as git submodules.
+  Util that time look into the git history.
+
 ## Road Map <a name="road-map"></a>
 
+- Add support for reading/writing custom characters to memory/display
+- Add examples projects utilizing lcdLib as git submodules
+- Finish documenting functions
+- Put the [doxygen][] generated documentation for this library online
