User friendly non specialist setup guide

[Kihon]

I REALLY want to get a RPi with an attached USB SSD with my music files on it up and running connected by RCA outs on the HiFiBerry DAC+, controlled from Android phone.

Surely in 2020 this is possible without having to be a network guru or computer programmer!!!

So......

Could someone, preferably the developers please write a set up and user guide that does not assume one is a network expert or advanced computer user.

I am an average computer user.
I have built (plugged together!) a Pi with the HiFiberry DAC+.
I can install and run lots of software on PC but I do NOT know all the network jargon nor how networks work.
The setup instructions are totally inadequate for an average user.
On the http://moodeaudio.org main web page it says to download the image and install it on a SD card but it doesn't even tell me what size SD card I need!!!
The setup guide is linked to a texted based file on GitHub(?) whatever that is; why not have friendly laid out setup instructions on the main website?

The developers of these apps/programs need to realise that a lot of users are not network experts or advanced computer users but still want to use these and need clear jargon free instructions that do not assume advanced knowledge.

For example right from the start;

"NOTE: Use http://moode, moode.local or IP address, whichever works on your network.

Typically Android OS will only work with IP address. (What is this referring to)

- SSH login user: pi, pwd: moodeaudio (What does this mean, what is SSH?)
- Preface commands requiring root permission with sudo (What??!?!?!?)
- Access Point (AP) mode:
  (a) IP address: 172.24.1.1
  (b) SSID: Moode
  © Password: moodeaudio
  (d) Channel: 6
(I don't know how or when to use this information)
- AP mode starts automatically when:
  (a) WiFi SSID is set to 'None' in Network config and there is no Ethernet connection (?)
  (b) WiFi SSID is defined but no IP address was assigned by DHCP. This typically
  occurs when connection to the SSID fails. (What is DHCP?)
- Default Samba shares are NAS, Playlists, Radio, and SDCard (What is SAMBA?)
- Each USB disk will also have a Samba share named after its Disk Label
(When I am supposed to need all the above)

Is there really any need for this to be so elitist, only for network experts or advanced computer users.




Thanks.
