+
+Extremely fast utf8-only stream implementation to write to files and
+file descriptors.
+
+This implementation is partial, but support backpressure and `.pipe()` in is here.
+However, it is 2-3x faster than Node Core `fs.createWriteStream()`:
+
+```
+benchSonic*1000: 1916.904ms
+benchSonicSync*1000: 8605.265ms
+benchSonic4k*1000: 1965.231ms
+benchSonicSync4k*1000: 1588.224ms
+benchCore*1000: 5851.959ms
+benchConsole*1000: 7605.713ms
+```
+
+Note that sync mode without buffering is _slower_ than a Node Core WritableStream, however
+this mode matches the expected behavior of `console.log()`.
+
+Note that if this is used to log to a windows terminal (`cmd.exe` or
+powershell), it is needed to run `chcp 65001` in the terminal to
+correctly display utf-8 characters, see
+[chcp](https://ss64.com/nt/chcp.html) for more details.
+
+## Install
+
+```
+npm i sonic-boom
+```
+
+## Example
+
+```js
+'use strict'
+
+const SonicBoom = require('sonic-boom')
+const sonic = new SonicBoom({ fd: process.stdout.fd }) // or { dest: '/path/to/destination' }
+
+for (let i = 0; i < 10; i++) {
+  sonic.write('hello sonic\n')
+}
+```
+
+## API
+
+### SonicBoom(opts)
+
+Creates a new instance of SonicBoom.
+
+The options are:
+
+* `fd`: a file descriptor, something that is returned by `fs.open` or
+   `fs.openSync`.
+* `dest`: a string that is a path to a file to be written to (mode controlled by the `append` option).
+* `minLength`: the minimum length of the internal buffer that is
+  required to be full before flushing.
+* `maxLength`: the maximum length of the internal buffer. If a write operation would cause the buffer
+  to exceed `maxLength`, the data written is dropped and a `drop` event is emitted with the dropped data
+* `maxWrite`: the maximum number of bytes that can be written; default: 16384
+* `sync`: perform writes synchronously (similar to `console.log`).
+* `fsync`: perform a [fsyncSync](https://nodejs.org/api/fs.html#fsfsyncsyncfd) every time a write is completed.
+* `append`: appends writes to dest file instead of truncating it (default `true`).
+* `mode`: specify the creating file `mode` (see [fs.open()](https://nodejs.org/api/fs.html#fsopenpath-flags-mode-callback) from Node.js core).
+* `mkdir`: ensure directory for dest file exists when `true` (default `false`).
+* `retryEAGAIN(err, writeBufferLen, remainingBufferLen)`: a function that will be called when sonic-boom
+    write/writeSync/flushSync encounters a EAGAIN or EBUSY error. If the return value is
+    true sonic-boom will retry the operation, otherwise it will bubble the
+    error. `err` is the error that caused this function to be called,
+    `writeBufferLen` is the length of the buffer sonic-boom tried to write, and
+    `remainingBufferLen` is the length of the remaining buffer sonic-boom didn't try to write.
+
+For `sync:false`  a `SonicBoom` instance will emit the `'ready'` event when a file descriptor is available.
+For `sync:true` this is not relevant because the `'ready'` event will be fired when the `SonicBoom` instance is created, before it can be subscribed to.
+
+
+### SonicBoom#write(string)
+
+Writes the string to the file.
+It will return false to signal the producer to slow down.
+
+### SonicBoom#flush([cb])
+
+Writes the current buffer to the file if a write was not in progress.
+Do nothing if `minLength` is zero or if it is already writing.
+
+call the callback when the flush operation is completed. when failed the callback is called with an error.
+
+### SonicBoom#reopen([file])
+
+Reopen the file in place, useful for log rotation.
+
+Example:
+
+```js
+const stream = new SonicBoom('./my.log')
+process.on('SIGUSR2', function () {
+  stream.reopen()
+})
+```
+
+### SonicBoom#flushSync()
+
+Flushes the buffered data synchronously. This is a costly operation.
+
+### SonicBoom#end()
+
+Closes the stream, the data will be flushed down asynchronously
+
+### SonicBoom#destroy()
+
+Closes the stream immediately, the data is not flushed.
+
+### Events
+
+
+#### SonicBoom#close
+
+See [Stream#close](https://nodejs.org/api/stream.html#event-close). The `'close'` event when the instance has been closed.
+
+#### SonicBoom#drain
+
+See [Stream#drain](https://nodejs.org/api/stream.html#event-drain). The `'drain'` event is emitted when source can resume sending data.
+
+#### SonicBoom#drop <any>
+
+When destination file maximal length is reached, the `'drop'` event is emitted with data that could not be written. 
+
+#### SonicBoom#error <Error>
+
+The `'error'` event is emitted when the destination file can not be opened, or written.
+
+#### SonicBoom#finish
+
+See [Stream#finish](https://nodejs.org/api/stream.html#event-finish). The `'finish'` event after calling `end()` method and when all data was written.
+
+#### SonicBoom#ready
+
+The `'ready'` event occurs when the created instance is ready to process input.
+
+#### SonicBoom#write <number>
+
+The `'write'` event occurs every time data is written to the underlying file. It emits the number of written bytes.
