+ **Project description** 
+
+The neotime module defines classes for working with temporal data to nanosecond precision. 
+These classes comprise a similar set to that provided by the standard library datetime module. 
+Inspiration has also been drawn from ISO-8601.
+
+ **Overview** 
+
+The classes are listed below:
+
+Duration
+
+Date
+
+Time
+
+DateTime
+
+TODO
+
+
+ **Installation** 
+
+To install the latest stable version of neotime, simply use pip:
+
+$ pip install --pre neotime
+
+Or to install the latest bleeding edge code directly from GitHub, use:
+
+$ pip install git+https://github.com/technige/neotime.git#egg=neotime
+
+Note that code installed directly from GitHub is likely to be unstable. Your mileage may vary.
+
+ **More Information** 
+
+For more information, read the docs.
