+## How To Go Fast
+
+You can help the algorithm go fast by providing prepared targets instead of raw strings. Preparing strings is slow, do this ahead of time and only prepare each target once.
+
+```js
+myObj.titlePrepared = fuzzysort.prepare(myObj.title)
+fuzzysort.single(search, myObj.titlePrepared)
+```
+
+
 ### Advanced Usage
 
 Search a list of objects, by multiple fields, with custom weights.
