Installing Bots

Matrix Synapse currently does not have a concept of bots, a bot is just a normal user. Usally there is a config and a .py file, download the files, unpack them and run the .py file. Running and downloading things via pip is not recommended.

Install python3 

sudo apt install python3

then install pip 

sudo apt install python3-pip

then matrix-bot-api from pyp 

pip3 install matrix-bot-api

and finally fill out the config and start it 

python3 pollbot.py

Exclude a server from a channel
