I own 1.3534 Stock in my employer. I don’t understand what I own though, lol. Any advice?

I'm a newbie. My company offers stocks and they apparently match at end of year. People made a good profit in the past and really recommended it, so I bought some.

Currently: 1.3534 Shares, Available shares $249.91, Book Value $225.31. Previous Close $184.7000.

…….. what does that line mean?

Also what do I do with Stocks, What do you recommend?
