1. Clone the git using:

git clone https://github.com/shivasiddharth/Assistants-Pi  

2. Make the installers executable using:

sudo chmod +x /home/pi/Assistants-Pi/prep-system.sh    
sudo chmod +x /home/pi/Assistants-Pi/audio-test.sh   
sudo chmod +x /home/pi/Assistants-Pi/installer.sh  

3. Prepare the system for installing assistants by updating, upgrading and setting up audio using:

sudo /home/pi/Assistants-Pi/prep-system.sh

4. Restart the Pi using:

sudo reboot

5. Make sure that contents of asoundrc match the contents of asound.conf
   Open a terminal and type:

sudo nano /etc/asound.conf

Open a second terminal and type:

sudo nano ~/.asoundrc

If the contents of .asoundrc are not same as asound.conf, copy the contents from asound.conf to .asoundrc, save using ctrl+x and y

6. Test the audio setup using:

sudo /home/pi/Assistants-Pi/audio-test.sh  

7. Restart the Pi using:

sudo reboot

8. Install the assistant/assistants using the following. This is an interactive script, so just follow the onscreen instructions:

sudo /home/pi/Assistants-Pi/installer.sh  

9. After verification of the assistants, to make them auto start on boot:
   Pi 3 and Pi2 users, open the gassistpi-ok-google.service in the /home/pi/Assistants-Pi/systemd folder and add your project-id and model-id in the indicated points.
   Pi Zero users, open the gassistpi-push-button.service in the /home/pi/Assistants-Pi/systemd folder and add your project-id and model-id in the indicated points.
   After that, open a terminal and run the following commands:

sudo chmod +x /home/pi/Assistants-Pi/scripts/service-installer.sh
sudo chmod +x /home/pi/Assistants-Pi/scripts/clientstart.sh  
sudo chmod +x /home/pi/Assistants-Pi/scripts/companionstart.sh  
sudo chmod +x /home/pi/Assistants-Pi/scripts/wakeword.sh  
sudo /home/pi/Assistants-Pi/scripts/service-installer.sh  
sudo systemctl enable companionapp.service
sudo systemctl enable client.service
sudo systemctl enable wakeword.service
sudo systemctl enable stopbutton.service

#If using Pi 2B or Pi 3B

sudo systemctl enable gassistpi-ok-google.service  

#If using Pi zero

sudo systemctl enable gassistpi-push-button.service
