 * Embedded shared library support means users do not have to install FUSE from a 3rd party.
 * API support for initial FUSE kernel extension configuration so you can control the user experience.
 
+## Installation
+```
+npm i fuse-native --save
+```
+
+## Example
+```js
+const ops = {
+  readdir: function (path, cb) {
+    if (path === '/') return cb(null, ['test'])
+    return cb(Fuse.ENOENT)
+  },
+  getattr: function (path, cb) {
+    if (path === '/') return cb(null, stat({ mode: 'dir', size: 4096 }))
+    if (path === '/test') return cb(null, stat({ mode: 'file', size: 11 }))
+    return cb(Fuse.ENOENT)
+  },
+  open: function (path, flags, cb) {
+    return cb(0, 42)
+  },
+  release: function (path, fd, cb) {
+    return cb(0)
+  },
+  read: function (path, fd, buf, len, pos, cb) {
+    var str = 'hello world'.slice(pos, pos + len)
+    if (!str) return cb(0)
+    buf.write(str)
+    return cb(str.length)
+  }
+}
+
+const fuse = new Fuse(mnt, ops, { debug: true })
+fuse.mount(function (err) {
+  fs.readFile(path.join(mnt, 'test'), function (err, buf) {
+    // buf should be 'hello world'
+  })
+})
+```
+
 ## API
+In order to create a FUSE mountpoint, you first need to create a `Fuse` object that wraps a set of implemented FUSE syscall handlers:
+
+#### `const fuse = new Fuse(mnt, handlers, opts = {})`
+Create a new `Fuse` object.
+
+`mnt` is the string path of your desired mountpoint.
+`handlers` is an object mapping syscall names to implementations. The complete list of available syscalls is described below. As an example, if you wanted to implement a filesystem that only supports `getattr`, your handle object would look like:
+```js
+{
+  getattr: function (path, cb) {
+    if (path === '/') return process.nextTick(cb, null, stat({ mode: 'dir', size: 4096 }))
+    if (path === '/test') return process.nextTick(cb, null, stat({ mode: 'file', size: 11 }))
+    return process.nextTick(cb, Fuse.ENOENT)
+  }
+}
+```
+
+The following FUSE API methods are supported:
