A Bitbucket wiki is a repository like any other, you can clone it and push changes to it. To create content, the wiki uses Creole markup.

• Click the Wiki option on the repository menu bar.
  By default Bitbucket displays the wiki Home page.
• Click Edit.
• Make your changes to the page content.
  You may want to change the Welcome heading to say Welcome to the bb101repo.

• If you want to do something more elaborate but you aren't sure how, take the Wiki markup link to view the help. The Bitbucket wiki uses the Creole syntax.
• Enter a comment in the Message text box.
  This is a commit message. What you enter here will appear in the page history above the relevant commit entry.
• Click Save.
  The system displays your home page with the new heading.
