As the first step we need to create user with which permissions IoT framework will be running
sudo useradd --home-dir /home/tigase --create-home --system tigase
If you are installing Tigase IoT Framework on Raspberry PI and want to use GPIO, SPI or I2C connected devices then we need to add newly created user to proper groups
sudo usermod -a -G spi,i2c,gpio tigase
