I bought my first switch and it's a modded switch by the looks of it

I finally decided to buy a switch, because I saw a really great deal on facebook and found someone getting rid of their Switch OLED for like $230. I got it and turned it on it boots into hekate v6.2.2. I have never owned a switch before modded or not. I have no idea if it's up to date how to navigate it and generally what to do with it.
