I don’t know how to put the code in “squares” like my peers

To format a block as code on the forums you can use one of these options:

  • mark the code block with three backticks ``` (just left of the 1 key on US keyboard layout) before AND after the relevant text; or
  • select the text and then use the </> icon (near the middle of the top row of icons in the editor) to mark it as a code block (it will insert the backticks for you, same as above); or
  • indent each line by 4 spaces.

There is a helpful page on formatting posts on the HA forums.
