+# minizlib
+
+A fast zlib stream built on [minipass](http://npm.im/minipass) and
+Node.js's zlib binding.
+
+This module was created to serve the needs of
+[node-tar](http://npm.im/tar) and
+[minipass-fetch](http://npm.im/minipass-fetch).
+
+Brotli is supported in versions of node with a Brotli binding.
+
+## How does this differ from the streams in `require('zlib')`?
+
+First, there are no convenience methods to compress or decompress a
+buffer.  If you want those, use the built-in `zlib` module.  This is
+only streams.  That being said, Minipass streams to make it fairly easy to
+use as one-liners: `new zlib.Deflate().end(data).read()` will return the
+deflate compressed result.
+
+This module compresses and decompresses the data as fast as you feed
+it in.  It is synchronous, and runs on the main process thread.  Zlib
+and Brotli operations can be high CPU, but they're very fast, and doing it
+this way means much less bookkeeping and artificial deferral.
+
+Node's built in zlib streams are built on top of `stream.Transform`.
+They do the maximally safe thing with respect to consistent
+asynchrony, buffering, and backpressure.
+
+See [Minipass](http://npm.im/minipass) for more on the differences between
+Node.js core streams and Minipass streams, and the convenience methods
+provided by that class.
