After Installing Azusa's client, open it and make sure there is a server online, then simply press the Join button to get in
If you don't have an account, click on that link to get into the creation page
Fill the spaces to finish creating your account and, well see you in Azusa! Its pretty simple and quick!
Once you are online, you press New Character to get into the creation window, customize your character and you are free to start Roleplaying! See you there!
If you are confused in game and dont know what to do, try out the ingame starting guide!
If when you try to create your account, just a blank window appears, try creating directly on BYOND's website. If you still have problems logging in, try to also download and play through BYOND.
