+## errno exposed
+
+Ever find yourself needing more details about Node.js errors? Me too, so *node-errno* contains the errno mappings direct from libuv so you can use them in your code.
+
+**By errno:**
+
+```js
+require('errno').errno[3]
+// → {
+//     "errno": 3,
+//     "code": "EACCES",
+//     "description": "permission denied"
+//   }
+```
+
+**By code:**
+
+```js
+require('errno').code.ENOTEMPTY
+// → {
+//     "errno": 53,
+//     "code": "ENOTEMPTY",
+//     "description": "directory not empty"
+//   }
+```
+
+**Make your errors more descriptive:**
+
+```js
+var errno = require('errno')
+
+function errmsg(err) {
+  var str = 'Error: '
+  // if it's a libuv error then get the description from errno
+  if (errno.errno[err.errno])
+    str += errno.errno[err.errno].description
+  else
+    str += err.message
+
+  // if it's a `fs` error then it'll have a 'path' property
+  if (err.path)
+    str += ' [' + err.path + ']'
+
+  return str
+}
+
+var fs = require('fs')
+
+fs.readFile('thisisnotarealfile.txt', function (err, data) {
+  if (err)
+    console.log(errmsg(err))
+})
+```
+
+**Use as a command line tool:**
+
+```
+~ $ errno 53
+{
+  "errno": 53,
+  "code": "ENOTEMPTY",
+  "description": "directory not empty"
+}
+~ $ errno EROFS
+{
+  "errno": 56,
+  "code": "EROFS",
+  "description": "read-only file system"
+}
+~ $ errno foo
+No such errno/code: "foo"
+```
+
+Supply no arguments for the full list. Error codes are processed case-insensitive.
+
+You will need to install with `npm install errno -g` if you want the `errno` command to be available without supplying a full path to the node_modules installation.
+
+<a name="customerrors"></a>
+## Custom errors
+
+Use `errno.custom.createError()` to create custom `Error` objects to throw around in your Node.js library. Create error hierarchies so `instanceof` becomes a useful tool in tracking errors. Call-stack is correctly captured at the time you create an instance of the error object, plus a `cause` property will make available the original error object if you pass one in to the constructor.
+
+```js
+var create = require('errno').custom.createError
+var MyError = create('MyError') // inherits from Error
+var SpecificError = create('SpecificError', MyError) // inherits from MyError
+var OtherError = create('OtherError', MyError)
+
+// use them!
+if (condition) throw new SpecificError('Eeek! Something bad happened')
+
+if (err) return callback(new OtherError(err))
+```
+
+Also available is a `errno.custom.FilesystemError` with in-built access to errno properties:
+
+```js
+fs.readFile('foo', function (err, data) {
+  if (err) return callback(new errno.custom.FilesystemError(err))
+  // do something else
+})
+```
+
+The resulting error object passed through the callback will have the following properties: `code`, `errno`, `path` and `message` will contain a descriptive human-readable message.
