Hi, I am new to the projects and I am still learning but I am really exited for this projects.
I was trying to replicate the example in your website ->https://tendermint.com/docs/guides/go-built-in.html#guide-assumptions

but I found that some of the links are broken. For example the

protobuf file is missing.
Also I tried to find the documentation in github so to help with fixing this problem but I did not found it.

Note: If there is anyone that has some time to spend to guide me with this project I would really appreciate it. I need help to get what the mail problems of this project are and how can I be useful.
I would like to contribute however I can.
Thanks
