+How to connect Bitcoinlib to a Blockbook server
+===============================================
+
+Trezor's Blockbook is a back-end service for Trezor Suite and can also be used as back-end service provider for
+Bitcoinlib. Blockbook indexes addresses, transactions, unspent outputs and balances and can be used for fast
+blockchain queries. Blockbook also support Litecoin, Dash, Dogecoin and various testnets.
+
+If you want to use Bitcoinlib as a wallet, run many blockchain queries or write an application which is dependant on
+frequent requests to blockchain service providers you should use a Blockbook service or install a
+`Bcoin <manuals.setup-bcoin.html>`_ node.
+
+
+Install Blockbook server
+------------------------
+
+You can find some instructions on how to install a Blockbook server on
+https://coineva.com/blockbook-setup-as-bitcoinlib-backend.html.
+
+You will need a powerful server with enough memory and diskspace. Blockbook runs a full Bitcoin core node on the
+background, and maintains a large RocksDB database to store additional blockchain data. But once installed and
+synchronised it runs fast and smooth.
+
+
+Use Blockbook with Bitcoinlib
+-----------------------------
+
+To use Blockbook with bitcoinlib add the credentials to the providers.json configuration file in the .bitcoinlib directory.
+
+.. code-block:: json
+
+    "blockbook": {
+      "provider": "blockbook",
+      "network": "bitcoin",
+      "client_class": "BlockbookClient",
+      "provider_coin_id": "",
+      "url": "https://<servername>:9130/",
+      "api_key": "",
+      "priority": 20,
+      "denominator": 100000000,
+      "network_overrides": null
+    }
+
+You can increase the priority so the Service object always connects to the Blockbook service first.
