+# 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.
+
+Tested using tox with Python version 2.5, 2.6, 2.7, 3.1, 3.2 and 3.3.
+
+## Issues and contribution ##
+
+Bug reports are done by [creating an issue on Github](https://github.com/appliedsec/pygeoip/issues). If you want to contribute you can always [create a pull request](https://github.com/appliedsec/pygeoip/pulls) for discussion and code submission.
+
+## Installation ##
+
+You can easily install pygeoip with setuptools:
+
+    easy_install pygeoip
+
+## Supported Databases ##
+
+* Country
+* Region
+* City
+* Organization
+* ISP
+* ASN
+
+## Quick Documentation ##
+
+Create your GeoIP instance with appropriate access flag. `STANDARD` reads data from disk when needed, `MEMORY_CACHE` loads database into memory on instantiation and `MMAP_CACHE` loads database into memory using mmap.
