Getting into Biking

Quick little note; I've always wanted to get into cycling but never went for it. I was recently given a bike and of course I took the opportunity.
I'm new to it all, so maybe some people can give me so insight on the bike. I'm not expecting for it to be the best or fastest, just happy to have a bike to begin the journey of cycling (if I plan to upgrade later in the future any tips on brand or what I should look for)? Just plan to ride around the area, for now.
Anything I should/could change for a better feel for me? Any tips when riding or just in general? Thank
