Hello and welcome to OpenStreetMap :)

we're happy to see you taking care of your business here.

As you're new to OSM it's easy to make "mistakes" but that's no problem. You can either fix them yourself or ask the community for help.

Since your business is *not* the golf course it's better tagged as
education=training
training=sport
sport=golf

Please also do not use the description for advertising copy. We are not google. Keep is short and to the point.

Your business hours should be set to a predefined format so all software reading our database can read them
