+
+### NymConnect Installation
+
+NymConnect application is for everyone who does not want to install and run `nym-socks5-client`. NymConnect is plug-and-play, fast and easy use. Electrum Bitcoin wallet, Monero wallet (desktop and CLI) and Matrix (Element app) connects through NymConnect automatically to the Mixnet.
+
+1. [Download](https://nymtech.net/download/nymconnect) NymConnect
+2. On Linux and Mac, make executable by opening terminal in the same directory and run:
+
+```sh
+chmod +x ./nym-connect_<VERSION>.AppImage
+```
+
+3. Start the application
+4. Click on `Connect` button to initialise the connection with the Mixnet
+5. Anytime you'll need to setup Host and Port in your applications, click on `IP` and `Port` to copy the values to clipboard
+6. In case you have problems such as `Gateway Issues`, try to reconnect or restart the application
+
+### Firo Electrum wallet via NymConnect
+
+
+To download Firo Electrum wallet visit the [Firo's repository](https://github.com/firoorg/firo) or [Github release page](https://github.com/firoorg/electrum-firo/releases/tag/4.1.5.2). To connect to the Mixnet follow these steps:

+2. Start your Firo Electrum wallet
+3. Go to: *Tools* -> *Network* -> *Proxy*
+4. Set *Use proxy* to ✅, choose `SOCKS5` from the drop-down and add the values from your NymConnect application
+5. Now your Firo Electrum wallet runs through the Mixnet and it will be connected only if your NymConnect or `nym-socks5-client` are connected.
