I use Bitchat Android app. How can I safely message other users around me via Bluetooth? How do I join a channel and send a private message using commands such as /j, /m and /w within the application? Please explain simply the functions of these commands and the working logic of the mesh network.

Before starting, check which OS we are on and if the necessary tools (e.g., Python, Node.js, Git, Docker) are installed. Install any missing ones step-by-step according to this system.
Create a new, empty folder to work in. Do not touch any files outside this folder and do not delete anything. Tell me what you are going to do in one sentence before running each command.
