After hitting GENERATE PASTE CODE, copy the output and open brainstew.html in a text editor.

1. Find the comment:
   <!-- ADD POSTS HERE -->
   Paste the inbox row HTML there.
2. 
   Find the comment:
   <!-- add more markdown posts here -->
   Paste the markdown script block there.
3. 
   Update the statusbar message count if you want.
4. 
   Save and upload to Neocities. Done!! ♥

Or just upload a .md file directly to brainstew.html using the Open .md button in the toolbar — it'll render immediately without editing any HTML!
