Since I already have some experience creating posts on @steem-atlas, I want to share some information.

To create your own post, you need to go to the website
SteemAtlas and click on button No. 1 (as shown in the screenshot)

As a result, you will be asked to set a label on the map that corresponds to your location.

As soon as you put a label on the map, an editor opens for you in which you can create your post.

Be sure to include #hive-109690 as the first tag, then the post will appear in our community.
It is advisable to specify the beneficiary -steem-atlas- to support the development of the project.

I hope that my words will help you navigate this program faster.
