+Description
+===========
+
+streamsearch is a module for [node.js](http://nodejs.org/) that allows searching a stream using the Boyer-Moore-Horspool algorithm.
+
+This module is based heavily on the Streaming Boyer-Moore-Horspool C++ implementation by Hongli Lai [here](https://github.com/FooBarWidget/boyer-moore-horspool).
+
+
+Requirements
+============
+
+* [node.js](http://nodejs.org/) -- v10.0.0 or newer
+
+
+Installation
+============
+
+    npm install streamsearch
+
+Example
+=======
+
+```js
+  const { inspect } = require('util');
+
+  const StreamSearch = require('streamsearch');
+
+  const needle = Buffer.from('\r\n');
+  const ss = new StreamSearch(needle, (isMatch, data, start, end) => {
+    if (data)
+      console.log('data: ' + inspect(data.toString('latin1', start, end)));
+    if (isMatch)
+      console.log('match!');
+  });
+
+  const chunks = [
+    'foo',
+    ' bar',
+    '\r',
+    '\n',
+    'baz, hello\r',
+    '\n world.',
+    '\r\n Node.JS rules!!\r\n\r\n',
+  ];
+  for (const chunk of chunks)
+    ss.push(Buffer.from(chunk));
+
+  // output:
+  //
+  // data: 'foo'
+  // data: ' bar'
+  // match!
+  // data: 'baz, hello'
+  // match!
+  // data: ' world.'
+  // match!
+  // data: ' Node.JS rules!!'
+  // match!
+  // data: ''
+  // match!
+```

+
+Properties
+----------
+
+* **maxMatches** - < _integer_ > - The maximum number of matches. Defaults to `Infinity`.
+
+* **matches** - < _integer_ > - The current match count.
+
+
+Functions
+---------
+
+* **(constructor)**(< _mixed_ >needle, < _function_ >callback) - Creates and returns a new instance for searching for a _Buffer_ or _string_ `needle`. `callback` is called any time there is non-matching data and/or there is a needle match. `callback` will be called with the following arguments:
+
+  1. `isMatch` - _boolean_ - Indicates whether a match has been found
+
+  2. `data` - _mixed_ - If set, this contains data that did not match the needle.
+
+  3. `start` - _integer_ - The index in `data` where the non-matching data begins (inclusive).
+
+  4. `end` - _integer_ - The index in `data` where the non-matching data ends (exclusive).
+
+  5. `isSafeData` - _boolean_ - Indicates if it is safe to store a reference to `data` (e.g. as-is or via `data.slice()`) or not, as in some cases `data` may point to a Buffer whose contents change over time.
+
+* **destroy**() - _(void)_ - Emits any last remaining unmatched data that may still be buffered and then resets internal state.
+
+* **push**(< _Buffer_ >chunk) - _integer_ - Processes `chunk`, searching for a match. The return value is the last processed index in `chunk` + 1.
+
+* **reset**() - _(void)_ - Resets internal state. Useful for when you wish to start searching a new/different stream for example.
