+# tiny-inflate
+
+This is a port of Joergen Ibsen's [tiny inflate](https://bitbucket.org/jibsen/tinf) to JavaScript.
+Minified it is about 3KB, or 1.3KB gzipped. While being very small, it is also reasonably fast
+(about 30% - 50% slower than [pako](https://github.com/nodeca/pako) on average), and should be 
+good enough for many applications. If you need the absolute best performance, however, you'll
+need to use a larger library such as pako that contains additional optimizations.
+
+## Installation
+
+    npm install tiny-inflate
+
+## Example
+
+To use tiny-inflate, you need two things: a buffer of data compressed with deflate,
+and the decompressed size (often stored in a file header) to allocate your output buffer.
+Input and output buffers can be either node `Buffer`s, or `Uint8Array`s.
+
+```javascript
+var inflate = require('tiny-inflate');
+
+var compressedBuffer = new Bufer([ ... ]);
+var decompressedSize = ...;
+var outputBuffer = new Buffer(decompressedSize);
+
+inflate(compressedBuffer, outputBuffer);
+```
