yoursite.com/wp-admin. If you're already logged in, you can just visit your site and use the link from the admin bar at the top:Then press "Upload Plugin" (button is right where "Add New" used to be), and select the zip file we downloaded in the first step.
Once the upload is complete, you'll see a link that says "Activate plugin". Press that, and you're done. Nice!
We'll need to give SteemPress some information about our Steem account in order for it to make posts to the Steem blockchain with your account. To set this up, visit the plugin's setting page. Select "Plugins" from the left sidebar again, then scroll down til you find SteemPress and follow the "Settings" link.
Now you'll see three fields: Steem username, posting key, and default tags. The Steem username is just as it sounds, whatever you use to sign in to Steemit and other Steem services (no "@" symbol). Your posting key can be found in your wallet on Steemit. Click your avatar photo, then select wallet, and go to the permissions tab:
The first line will be for your posting key. Press the button on the right side that says "Show Private Key", then copy the string of text into the appropriate field of the SteemPress settings. Don't worry, this will only be stored on the server your site is hosted on.
Finally, choose your tags. These will be automatically added to any posts you make to Steem using SteemPress. When you're finished, hit the blue "Save all changes" button.
Ok, we're ready to make a post to WordPress and Steem, at the same time! This is actually the really easy part. Just publish your post on WordPress, and it'll automatically show up on Steem too.
That worked like a charm. Yay!
