-Npgsql - .NET Data Provider for PostgreSQL
-=============
-
-###What Is Npgsql?
-
-Npgsql is a .Net Data Provider for PostgreSQL. It allows you to connect and interact with PostgreSQL server using .NET.
-
-
-###Project Information

-+   [Npgsql source code @ GitHub][2]
-+   [Available on NuGet Gallery][3]

-Refer LICENSE.txt for more information on license terms.
-
-###Code history
-
-On December 2nd, [we committed a change][5] to restructure Npgsql code. This change modified file locations and unfortunately made the complete modification history of those files to not be available anymore through GitHub interface directly. [This stackoverflow post][6] documents a way to access the history before the rename: You just need to access the object tree **before** the rename and then you can see the rest of the file history.
-In the case of this rename, this is the tree: https://github.com/npgsql/Npgsql/tree/2f8928e4dee59275767de0df2ec41a654744a3bc
-
-This will help future searches for the history of the files. Note that you stil can access the complete history of the file through command line: `git log --follow ./newflodername/file`
