Shavuot feast

I'm not one for rituals, for ritual sake, but also want to keep the feasts as per Father's instruction.

I therefore want to learn from others.

Can you tell me below how do you keep Shavuot?

I totally understand that sometimes we do things during feasts for remembrance sake and there is no Scripture to base it on so I won't split hairs on what you do. ? If you do have Scripture then please also share that.
