Updated the manual installation file to get everybody up and running.
There were missing requirements like the nginx installation and so on.
Now a first time linux user should be able to get this up and running.
In order to run over HTTPS* django requires the X-Forwarded-Proto header sent from the nginx proxy. I didn't add everything needed for TLS, but this header works with HTTP and HTTPS so I figure it might save a few people some time if they ever decide to secure their installation.
\* specifically, I noticed that image URLs are requested over HTTP instead of HTTPS even when the main page is HTTPS until this header is sent
I just went through a manual install on DietPi / Debian Unstable, and found that the manual needed some improving, this method works, whereas following the original manual was not a success for me.
The only line I would say I am unsure about is this one:
"Give the user permissions: `chown -R recipes:www-data /var/www/recipes`"
As I am not sure whether these permissions are necessary for this to work.
Hope this is useful, let me know if I can make further improvements.
