-A simple connection with BigchainDB can be established like this.
+A simple connection with a BigchainDB node can be established like this:
 
 .. code-block:: js
 
 	const conn = new driver.Connection(API_PATH)
 
-It is also possible to connect to a node of the BigchainDB test network.
-To do so, you need to pass the **app_id and app_key**.
+If the BigchainDB node requires special HTTP request headers
+(such as ``app_id`` and ``app_key``),
+they can be included like this:
 
 .. code-block:: js
 
-	const conn = new driver.Connection('https://test.bigchaindb.com/api/v1/', {
-		app_id: 'Get one from testnet.bigchaindb.com',

 Cryptographic Identities Generation

 Alice and Bob are represented by public/private key pairs. The private key is
 used to sign transactions, meanwhile the public key is used to verify that a
 signed transaction was indeed signed by the one who claims to be the signee.

 Querying for Metadata

 Similar as querying for assets, in BigchainDB you can query for metadata using simple text search.
 This search is applied to all the strings inside the metadata payload and returns all the metadata payloads that match a given text search string.
