 A fuzzy string set data structure for approximate string matching. This implementation is based on the Python and JavaScript libraries with the same name:
 
 * [JavaScript version](https://github.com/Glench/fuzzyset.js)
 * [Python version](https://github.com/axiak/fuzzyset)
+
+## Install
+
+```
+cabal install fuzzyset
+```
+
+For details, see [Hackage docs](http://hackage.haskell.org/package/fuzzyset). This library is also available on [Stackage](https://www.stackage.org/package/fuzzyset). To install using [Stack](https://www.haskellstack.org/):
+
+```
+stack install fuzzyset
+```
