 # Pure Python GeoIP API #
-The API is based on [MaxMind's C-based Python API](http://dev.maxmind.com/geoip/downloadable#Python-5),
-but the code itself is ported from the [Pure PHP GeoIP API](http://pear.php.net/package/Net_GeoIP) by Jim Winstead and Hans Lellelid.
 
-It is mostly a drop-in replacement, except the `new` and `open` methods are gone.
+This library is based on [Maxmind's GeoIP C API](https://github.com/maxmind/geoip-api-c).
 
-Tested using tox with Python version 2.5, 2.6, 2.7, 3.1, 3.2 and 3.3.
