nebula-chat's chatengine: i2pgram fork

An open source mtproto server engine implemented in go language with compatible Telegram clients.

Quick start

1. Run sudo apt install docker docker-compose in your shell;
2. git clone --recursive git@github.com:i2pgram/chatengine.git && cd chatengine
3. Edit ./docker-compose.yml: replace timezone with your own. There were reports that having a wrong timezone makes chatengine fail.
4. Run sudo make command in your shell;
5. Now, chatengine is running on your host's TCP port 12345;
6. Use i2pgram clients to connect to nebula-chat chatengine;
7. Enjoy!
