+Module for calculating Cyclic Redundancy Check (CRC) for Node.js and the Browser.
+
+# Important: Node >= 6.3.0 < 6.9.2
+
+There's was a bug in Node [#9342](https://github.com/nodejs/node/issues/9342) that affected CRC calculation if `Buffer.split()` is used (see issue discussion for details). This affected all version starting from `6.3.0` up to but not including `6.9.2`. The patch [#9341](https://github.com/nodejs/node/pull/9341) was released in `6.9.2`. If you are upgrading and seeing odd CRC calculation mismatches, this might be the reason.
+
+## Features
+
+* Full test suite comparing values against reference `pycrc` implementation.
+* Pure JavaScript implementation, no dependencies.
+* Provides CRC tables for optimized calculations.
+* Provides support for the following CRC algorithms:
+  * CRC1 `crc.crc1(…)`
+  * CRC8 `crc.crc8(…)`
+  * CRC8 1-Wire `crc.crc81wire(…)`
+  * CRC16 `crc.crc16(…)`
+  * CRC16 CCITT `crc.crc16ccitt(…)`
+  * CRC16 Modbus `crc.crc16modbus(…)`
+  * CRC16 Kermit `crc.crc16kermit(…)`
+  * CRC16 XModem `crc.crc16xmodem(…)`
+  * CRC24 `crc.crc24(…)`
+  * CRC32 `crc.crc32(…)`
+  * CRCJAM `crc.crcjam(…)`
+
+## Installation
+
+```
+npm install crc
+```
+
+## Usage
+
+Calculate a CRC32:
+
+```js
+const crc = require('crc');
+
+crc.crc32('hello').toString(16);
+// "3610a686"
+```
+
+Calculate a CRC32 of a file:
+
+```js
+crc.crc32(fs.readFileSync('README.md', 'utf8')).toString(16);
+// "127ad531"
+```
+
+Or using a `Buffer`:
+
+```js
+crc.crc32(fs.readFileSync('README.md')).toString(16);
+// "127ad531"
+```
+
+Incrementally calculate a CRC32:
+
+```js
+value = crc.crc32('one');
+value = crc.crc32('two', value);
+value = crc.crc32('three', value);
+value.toString(16);
+// "9e1c092"
+```
+
+For web distribution, it's best to require specific modules that you need to avoid bundling unnecessary code.
+
+```js
+const crc32 = require('crc/lib/crc32');
+
+crc32('hello').toString(16);
+// "3610a686"
+```
+
+## Running tests
+
+```
+npm test
+```
+
