+
+Install
+-------
+
+    npm i --save klaw
+
+If you're using Typescript, we've got [types](https://github.com/DefinitelyTyped/DefinitelyTyped/pull/11492/files):
+
+    npm i --save-dev @types/klaw
+
+
+Name
+----
+
+`klaw` is `walk` backwards :p
+
+
+Sync
+----
+
+If you need the same functionality but synchronous, you can use [klaw-sync](https://github.com/manidlou/node-klaw-sync).
+
+
+Usage
+-----
+
+### klaw(directory, [options])
+
+Returns a [Readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable) that iterates
+through every file and directory starting with `dir` as the root. Every `read()` or `data` event
+returns an object with two properties: `path` and `stats`. `path` is the full path of the file and
+`stats` is an instance of [fs.Stats](https://nodejs.org/api/fs.html#fs_class_fs_stats).
+
+- `directory`: The directory to recursively walk. Type `string`.
+- `options`: [Readable stream options](https://nodejs.org/api/stream.html#stream_new_stream_readable_options) and
+the following:
+  - `queueMethod` (`string`, default: `'shift'`): Either `'shift'` or `'pop'`. On `readdir()` array, call either `shift()` or `pop()`.
+  - `pathSorter` (`function`, default: `undefined`): Sorting [function for Arrays](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort).
+  - `fs` (`object`, default: [`graceful-fs`](https://github.com/isaacs/node-graceful-fs)): Use this to hook into the `fs` methods or to use [`mock-fs`](https://github.com/tschaub/mock-fs)
+  - `filter` (`function`, default: `undefined`): Filtering [function for Arrays](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter)
+  - `depthLimit` (`number`, default: `undefined`): The number of times to recurse before stopping. -1 for unlimited.
+  - `preserveSymlinks` (`boolean`, default: `false`): Whether symlinks should be followed or treated as items themselves. If true, symlinks will be returned as items in their own right. If false, the linked item will be returned and potentially recursed into, in its stead.
+
+**Streams 1 (push) example:**
+
+```js
+const klaw = require('klaw')
+
+const items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .on('data', item => items.push(item.path))
+  .on('end', () => console.dir(items)) // => [ ... array of files]
+```
+
+**Streams 2 & 3 (pull) example:**
+
+```js
+const klaw = require('klaw')
+
+const items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .on('readable', function () {
+    let item
+    while ((item = this.read())) {
+      items.push(item.path)
+    }
+  })
+  .on('end', () => console.dir(items)) // => [ ... array of files]
+```
+
+### Error Handling
+
+Listen for the `error` event.
+
+Example:
+
+```js
+const klaw = require('klaw')
+
+klaw('/some/dir')
+  .on('readable', function () {
+    let item
+    while ((item = this.read())) {
+      // do something with the file
+    }
+  })
+  .on('error', (err, item) => {
+    console.log(err.message)
+    console.log(item.path) // the file the error occurred on
+  })
+  .on('end', () => console.dir(items)) // => [ ... array of files]
+```
+
+
+### Aggregation / Filtering / Executing Actions (Through Streams)
+
+On many occasions you may want to filter files based upon size, extension, etc.
+Or you may want to aggregate stats on certain file types. Or maybe you want to
+perform an action on certain file types.
+
+You should use the module [`through2`](https://www.npmjs.com/package/through2) to easily
+accomplish this.
+
+Install `through2`:
+
+    npm i --save through2
+
+
+**Example (skipping directories):**
+
+```js
+const klaw = require('klaw')
+const through2 = require('through2')
+
+const excludeDirFilter = through2.obj(function (item, enc, next) {
+  if (!item.stats.isDirectory()) this.push(item)
+  next()
+})
+
+const items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .pipe(excludeDirFilter)
+  .on('data', item => items.push(item.path))
+  .on('end', () => console.dir(items)) // => [ ... array of files without directories]
+```
+
+**Example (ignore hidden directories):**
+
+```js
+const klaw = require('klaw')
+const path = require('path')
+
+const filterFunc = item => {
+  const basename = path.basename(item)
+  return basename === '.' || basename[0] !== '.'
+}
+
+klaw('/some/dir', { filter: filterFunc })
+  .on('data', item => {
+    // only items of none hidden folders will reach here
+  })
+```
+
+**Example (totaling size of PNG files):**
+
+```js
+const klaw = require('klaw')
+const path = require('path')
+const through2 = require('through2')
+
+let totalPngsInBytes = 0
+const aggregatePngSize = through2.obj(function (item, enc, next) {
+  if (path.extname(item.path) === '.png') {
+    totalPngsInBytes += item.stats.size
+  }
+  this.push(item)
+  next()
+})
+
+klaw('/some/dir')
+  .pipe(aggregatePngSize)
+  .on('data', item => items.push(item.path))
+  .on('end', () => console.dir(totalPngsInBytes)) // => total of all pngs (bytes)
+```
+
+
+**Example (deleting all .tmp files):**
+
+```js
+const fs = require('fs')
+const klaw = require('klaw')
+const through2 = require('through2')
+
+const deleteAction = through2.obj(function (item, enc, next) {
+  this.push(item)
+
+  if (path.extname(item.path) === '.tmp') {
+    item.deleted = true
+    fs.unlink(item.path, next)
+  } else {
+    item.deleted = false
+    next()
+  }
+})
+
+const deletedFiles = []
+klaw('/some/dir')
+  .pipe(deleteAction)
+  .on('data', item => {
+    if (!item.deleted) return
+    deletedFiles.push(item.path)
+  })
+  .on('end', () => console.dir(deletedFiles)) // => all deleted files
+```
+
+You can even chain a bunch of these filters and aggregators together. By using
+multiple pipes.
+
+**Example (using multiple filters / aggregators):**
+
+```js
+klaw('/some/dir')
+  .pipe(filterCertainFiles)
+  .pipe(deleteSomeOtherFiles)
+  .on('end', () => console.log('all done!'))
+```
+
+**Example passing (piping) through errors:**
+
+Node.js does not `pipe()` errors. This means that the error on one stream, like
+`klaw` will not pipe through to the next. If you want to do this, do the following:
+
+```js
+const klaw = require('klaw')
+const through2 = require('through2')
+
+const excludeDirFilter = through2.obj(function (item, enc, next) {
+  if (!item.stats.isDirectory()) this.push(item)
+  next()
+})
+
+const items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .on('error', err => excludeDirFilter.emit('error', err)) // forward the error on
+  .pipe(excludeDirFilter)
+  .on('data', item => items.push(item.path))
+  .on('end', () => console.dir(items)) // => [ ... array of files without directories]
+```
+
+
+### Searching Strategy
+
+Pass in options for `queueMethod`, `pathSorter`, and `depthLimit` to affect how the file system
+is recursively iterated. See the code for more details, it's less than 50 lines :)
