 with multiple words, confusion over homonyms etc). Also, geograpy3 is compatible with Python 3, unlike geograpy2.

 What it is
 ==========
 
-geograpy extracts place names from a URL or text, and add context to those names -- for example distinguishing between a country, region or city.
+geograpy extracts place names from a URL or text, and adds context to those names -- for example distinguishing between a country, region or city.
+
+The extraction is a two step process. The first process is a Natural Language Processing task which analyzes a text for potential mentions of geographic locations. In the next step the words which represent such locations are looked up using the Locator.
+
+If you already know that your content has geographic information you might want to use the Locator interface directly.
