 ## Overview
 Monica is an open-source web application to organize the interactions with your loved ones. I call it a PRM, or Personal Relationship Management. Think of it as a [CRM](https://en.wikipedia.org/wiki/Customer_relationship_management) (a popular tool used by sales teams in the corporate world) for your friends or family.

-#### Multi-user support

-**First User Registration:** Visit the app **domain** after the installation is complete to register as **first user**. After the first user is registered the registration will be **locked**. You can open the register for all by changing the value **APP_DISABLE_SIGNUP** to **false** in **.env**. There is **no admin interface** in the Monica app currently.
+- **First User:** An email with credentials for login will be sent to user who was chosen while the installation process of Monica. There is no **admin interface** on Monica, so every registered users will considered as normal user.
