So created a SD Card. What then?

Hello everyone, sorry if this seems a bit trivial as a question but I'm a complete neophyte.

So I just created the SD Card with LibreElec, and I realize there are probably some other steps I should take before plugging this in my TV. Is there some sort of manual/hand-me notes available that could help me in figuring out what's next? You know, stuff like:

- Should I activate miniHDMI port on my RPi4B?

- If I'm using wireless keyboard, does it need to be identified as well?

Like I said, I am completely new to Kodi and LibreELEC, but I should be smart enough to understand your replies (and they may spark more questions!)

EDIT: Think I forgot to mention that I did plug my SD card in my RPi4, but nothing came up on the screen: no boot sequence, no signal, nothing. So I'm wondering if I missed a step somewhere.

Thanks for these quick replies, and sorry for not being as forthcoming!

The RPi4 2Gb did work, as Klojum mentioned the cable had to be on the HDMI0 for the screen. I used the LibreELEC SD creator tool with a 16Gb card, and despite it closing as I shut the Terminal window, I could use the downloaded file and copy it in a subsequent operation. I am now using a USB dongle keyboard/mouse combo, and it works really well! I am currently on Linux (Ubuntu 20.04.02 LTS on an old AMD Phenom Quadcore CPU and even older ASUS Mobo) and loving it, having moved away from Windows some years ago. (Just to be clear, the RPi4 only has LibreELEC OS for Kodi!)

But I still got issues with Kodi/some add-ons though.

- My subscribed services seems to be working: I've managed to add the Netflix add-on, but I realize that some movies and series in "My List" cannot be seen (or found) with Kodi. Is there a reason for this? I am using a VPN that ensures I'm in the correct location (manually switching the server location before changing the add-on being used).

- Some default add-ons let me see the movie lists (like the PopCornFlix and Comet TV add-ons) but if I try to play a movie, I get an error log message (wish I could be more specific!)

- When consulting message boards and tutorials, it appears I am missing some add-ons sources like fusionco repository that allows for GitHub add-ons (I did activate the 3rd party source in Kodi). Is this normal in Kodi Leia 18.9?

- If I want to develop my own add-ons (because I can't find adequate add-ons already available) can anyone point me to an effective tutorial for add-on development? I admit I'm no developper/coder, but willing to learn. Apparently I'll stop learning when I die

Thanks in advance

Quote from Klojum

any add-on solution that facilitates video piracy in any way is off-limits.

Sure, it does make sense especially if most add-ons (like Netflix) require users to have an valid account. But i'll go read the rules anyway

Let's try if this link works:

And a link to the errorLog after Debugging, with attempting add-ons again:

Please let me know if I screwed the instructions, or if I understood those correctly!
