Want to have your post on the map too?

1. Go to Steemitworldmap
2. Click the code slider at the bottom
3. Click on the map where your post should be (zoom in if needed)
4. Copy and paste the generated code in your post (you can use Edit feature for this post of yours)
5. Wait for this message "Congrats, your post is now on the map!"
