Hello, Artem Duplinskiy! Welcome to Wikivoyage.
To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. If you are familiar with Wikipedia, take a look over some of the differences here.
Your listing in the Tanzania article was reverted. I'd encourage you to look at tour and welcome, business owners for reference, but safari tour companies can be listed on this site if you actually directly employ the porters (etc.). However, the listing cannot be in the article for the entire country, but needs to be in the article for the city where you are headquartered, or failing that, the article for the nearest city.
All the best,
