+# PostgreSQL Git Foreign Data Wrapper
+
+git\_fdw is a a Git Foreign Data Wrapper for PostgreSQL written in C.
+It is making use of ]`libgit2`](libgit2.github.com).
+
+## INSTALLATION
+
+### Prerequisites
+
+* libgit2-dev
+
+
+### Setup
+
+Building git\_fdw is as simple as
+
+    make
+
+and installing it only requires oneself to
+
+    make install
+
+
+Now you can start setting up your environment to access git repositories:
+
+    λ psql
+    psql (9.3.5)
+    Type "help" for help.
+    
+    franck=# CREATE EXTENSION git_fdw;
+    CREATE EXTENSION
+
+    franck=# CREATE SERVER git_fdw_server FOREIGN DATA WRAPPER git_fdw;
+    CREATE SERVER
+
+    franck=# CREATE FOREIGN TABLE rails_repository (message text, author text) SERVER git_fdw_server OPTIONS (path '/home/franck/rails/.git');
+    CREATE FOREIGN TABLE
+
+    franck=# SELECT * FROM rails_repository LIMIT 10;

+
+
+It is not possible to access multiple repositories through the same foreign
+table. We suggest the usage of views if this is something that needs to be
+achieved.
+
+## CONFIGURATION
+
+### Server
+
+There are no options that can be passed to a git\_fdw server.
+
+### Foreign Table
+
+The possible options are:
+
+* `path`: The path of the git repository;
+
+
+# Note on Patches/Pull Requests
+
+* Fork the project.
+* Make your feature addition or bug fix.
+* Add tests for it. This is important so I don't break it in a future version unintentionally.
+* Commit, do not mess with version or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
+* Send me a pull request. Bonus points for topic branches.
