This guide suggested a 2.5A power supply for the raspberry pi 4 (probably as a carryover from when it used to reference a raspberry pi 3B+). However, the official documentation suggests at least a 3A PSU for the pi 4 (https://www.raspberrypi.org/documentation/hardware/raspberrypi/power/README.md)
Also added clarification that the raspberry pi itself does not show a user interface if plugging in a display after seeing multiple posts on discord/the forum with confusion surrounding this.
Moves the note about the "CHECK CONFIG" button only being visible in advanced mode to the previous paragraph where it tells you to click the button. I was confused for a second until I read on to the next paragraph. It seems to make more sense to put the note about the button in the paragraph where it tells you to click the button.
I also made a couple other minor tweaks for consistency and accuracy.
* Slight addition to step 8
Some new users have expressed confusion about not being able to access the frontend at `http://hassio.local:8123` when the IP address works. Adding this note should hopefully reduce questions of this type.
* Update index.markdown
* Be consistent with Home Assistant spelling
* Refer to the Configurator without "HASS"
That's what's it calls itself and how it is in the add-on store.
* Be consistent with Hass.io spelling
* Tell vscode to spell HassOS like that
