Adding tags to your post on Smoke is very simple. You can add the #tags in your content and Smoke will automatically retrieve the first four tags in the content.
Just like #this.
If you post to the Smoke #blockchain via a different platform than Smoke.io the blockchain will retrieve the #five first tags. The first tag found will become the category of the post. On Smoke.io you can set the category for a post by selecting any category in the dropdown below the posting editor.
