# Basic Usage - Custom Servers

At the top of the app, when you opened it, is an input labeled Custom Server. The value inside of the input the first time you opened up the app is the server address of the default server, where most of the users chat. 

{% hint style="info" %}
Our default server is hosted on repl.it because we are charging no money to users using our application. But we have our special system to encrypt the server to make sure it isn't abused.
{% endhint %}

However, if you or your friend have created a custom server and want you to roleplay in it, they will send you a link to the server. Simply input that link into the input and press set, restart the app, and then you are good to go! 

{% hint style="info" %}
Sometimes connecting to a custom server will experience problems. Restarting the app will most likely resolve the issue. If it is not working after a few tries, contact the server owner.
