@@ -36,9 +37,9 @@ LevelDB is a simple key-value store built by Google. It's used in Google Chrome
 
 LevelDB stores entries sorted lexicographically by keys. This makes the [streaming interface](#createReadStream) of `levelup` - which exposes LevelDB iterators as [Readable Streams](https://nodejs.org/docs/latest/api/stream.html#stream_readable_streams) - a very powerful query mechanism.
 
-The most common store is [`leveldown`](https://github.com/level/leveldown/) which provides a pure C++ binding to LevelDB. [Many alternative stores are available](https://github.com/Level/awesome/#stores) such as [`level.js`](https://github.com/level/level.js) in the browser or [`memdown`](https://github.com/level/memdown) for an in-memory store. They typically support strings and Buffers for both keys and values. For a richer set of data types you can wrap the store with [`encoding-down`](https://github.com/level/encoding-down).

 Calling `levelup(db)` will also open the underlying store. This is an asynchronous operation which will trigger your callback if you provide one. The callback should take the form `function (err, db) {}` where `db` is the `levelup` instance. If you don't provide a callback, any read & write operations are simply queued internally until the store is fully opened.

 #### What happened to `db.createWriteStream`?
 
-`db.createWriteStream()` has been removed in order to provide a smaller and more maintainable core. It primarily existed to create symmetry with `db.createReadStream()` but through much [discussion](https://github.com/level/levelup/issues/199), removing it was the best course of action.
+`db.createWriteStream()` has been removed in order to provide a smaller and more maintainable core. It primarily existed to create symmetry with `db.createReadStream()` but through much [discussion](https://github.com/Level/levelup/issues/199), removing it was the best course of action.
 
 The main driver for this was performance. While `db.createReadStream()` performs well under most use cases, `db.createWriteStream()` was highly dependent on the application keys and values. Thus we can't provide a standard implementation and encourage more `write-stream` implementations to be created to solve the broad spectrum of use cases.

 ## Multi-process Access
 
 Stores like LevelDB are thread-safe but they are **not** suitable for accessing with multiple processes. You should only ever have a store open from a single Node.js process. Node.js clusters are made up of multiple processes so a `levelup` instance cannot be shared between them either.
