Hello @pear_3apple ,
Welcome to our TeamViewer Community and thanks for your question!
The first step to start using TeamViewer is by creating a TeamViewer account and then doing your login into TeamViewer on the local side of the connection.
Once you have TeamViewer installed, and your account logged in, you can start remotely connecting to your devices as well as saving your devices in your Computer & Contacts list.
💡Hint: For unattended access, please check our article: Remote control via Easy access.
Let me know if you have any questions about the process above.
I'm looking forward to your reply to better assist you! 🙋♀️
Best, Carol
