-### Fast & simple storage - a Node.js-style LevelDB wrapper**
+**LevelUP package helper for distributing with a LevelDOWN-compatible back-end**
 
-[![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/)

+**level-packager** exports single function which takes a single argument, a LevelDOWN-API compatible storage back-end for LevelUP. The function returns a constructor function that will bundle LevelUP with the given LevelDOWN replacement. The full API is supported, including all optional arguments, `repair()`, `delete()` and `copy()`. See **[level](https://github.com/Level/level)**, **[level-hyper](https://github.com/Level/level-hyper)** or **[level-lmdb](https://github.com/Level/level-lmdb)** as example use-cases.
 
-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.
+Also available is a *test.js* file that can be used to verify that the user-package works as expected.
 
-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.
