Setup instructions for Linux users

[NightMean]

Hello All,

I wanted to share my tutorial on how to run snap-camera-server on Linux instead of Windows via docker.
Why? I don't like the idea of running docker on my Windows machine just to have some server running so I've setup a Linux server where I host my other applications as well.

1. Make sure you have some Linux distro running. I will use Ubuntu for this.
2. Install OpenSSL if not already (should be installed with latest Ubuntu)
3. Download Snap-camera-server to some directory using git
   git clone https://github.com/ptrumpis/snap-camera-server.git
4. Navigate to the snap-camera-server directory
5. Rename the example environment file to .env
   mv example.env .env
6. Change permission to have gencert.sh executable
   chmod +x gencert.sh
7. Run the file to generate certificates
   (Not needed if you created SSL certificate previously and stored it somewhere. Valid for 10 years upon creation)
   ./gencert.sh
8. Move the generated certificate to system location in Linux
   sudo cp ./ssl/studio-app.snapchat.com.crt /usr/local/share/ca-certificates && sudo update-ca-certificates
9. Download the certificate file studio-app.snapchat.com.crt to your Windows machine e.g using SFTP
10. Import the certificate to your Windows machine according to the setup instructions
11. Run snap-camera-server on Linux via docker compose
    docker compose up
    If it throws some errors due to already allocated ports, adjust the config in .env file. For me I had to change both adminer ports (changed to 8181)
12. Modify the %SYSTEMROOT%\System32\drivers\etc\hosts in Windows according to the setup instructions to the IP of the server where you are running the application from. In my case, the server is locally hosted on IP: 192.168.1.11
    E.g. 192.168.1.11 studio-app.snapchat.com
13. Run Snap Camera on your Windows
14. Profit

Note: If you used snap-camera-server on your Windows PC before, you need to remove all previous studio-app.snapchat.com certificates and reinstall the app. After reinstall, it should work as expected :)

I would appreciate if such setup instructions could be also implemented to the official instructions as it was not hard at all to figure this by myself.
