@Alexis515 No, you are not ready to welcome guests. You should snooze your listing so it can't be booked yet, and take a look at how other hosts present their properties.
You have 5 photos that are all of the ground. You need to take photos of the accommodation you are providing- the bedroom, the bathroom, the kitchen, any living and outside areas the guests will have access to.
Then you need to describe the place and what you offer in the listing description.
And, as Emiel said, you can't list a room with one bed for 5 people. That makes no sense.
