+## API
+
+#### `const server = new BlobServer(store, options)`
+
+`store` - Corestore instance
+
+`options`:
+```js
+{
+  port // defaults to 49833,
+  host // defaults to '127.0.0.1',
+  token // server token
+  protocol // 'http' | 'https'
+}
+```
+
+#### `await server.listen()`
+Listen to requests
+
+#### `const link = server.getLink(key, options)`
+
+Generates the url used to fetch data
+
+`key` - hypercore or hyperdrive key
+
+`options`:
+```js
+{
+  host // custom host
+  port // custom port
+  protocol: 'http' | 'https',
+  filename | blob
+}
+```
+`filename` - hyperdrive filename
+
+`blob` - blob ID in the form of `{ blockOffset, blockLength, byteOffset, byteLength}`
+
+When downloading blobs, you can set the `Range` header to download sections of data, implement pause/resume download functionality. Offsets are zero-indexed & inclusive
+
+```
+Range: bytes=<start>-<end>
+Range: bytes=0-300
+Range: bytes=2-
+```
+
+#### `await server.suspend()`
+
+Let the instance know you wanna suspend so it can make relevant changes.
+
+#### `await server.resume()`
+
+Let the instance know you wanna resume from suspension. Will rebind the server etc.
