+Relies on `react-native-tcp` so it should be already installed and linked in RN project. `net` & `tls` dependencies should be
+injected via constructor, this library won't do `require('net')`.
+For RN you can place it in `shim.js`:
 
 ```javascript
   global.net = require('react-native-tcp');
 ```
 
-For nodejs it should be provided before usage:
+For nodejs simply
 
 ```javascript
-  global.net = require('net');
+  const net = require('net');
 ```

+  const client = new ElectrumClient(net, false, 50001, 'electrum1.bluewallet.io', 'tcp');
