+
+### Fast & simple storage - a Node.js-style LevelDB wrapper**
+
+[![NPM](https://nodei.co/npm/level.png?stars&downloads)](https://nodei.co/npm/level/) [![NPM](https://nodei.co/npm-dl/level.png)](https://nodei.co/npm/level/)
+
+
+This is a convenience package that bundles the current release of **[LevelUP](https://github.com/rvagg/node-levelup)** and **[LevelDOWN](https://github.com/rvagg/node-leveldown)** and exposes LevelUP on its export.
+
+Use this package to avoid having to explicitly install LevelDOWN when you just want plain old LevelDB from LevelUP.
+
+```js
+var level = require('level')
+
+// 1) Create our database, supply location and options.
+//    This will create or open the underlying LevelDB store.
+var db = level('./mydb')
+
+// 2) put a key & value
+db.put('name', 'Level', function (err) {
+  if (err) return console.log('Ooops!', err) // some kind of I/O error
+
+  // 3) fetch by key
+  db.get('name', function (err, value) {
+    if (err) return console.log('Ooops!', err) // likely the key was not found
+
+    // ta da!
+    console.log('name=' + value)
+  })
+})
+```
+
+See **[LevelUP](https://github.com/rvagg/node-levelup)** and **[LevelDOWN](https://github.com/rvagg/node-leveldown)** for more details.
