Before you can start storing important information in ~TiddlyWiki it is important to make sure that your changes are being reliably saved by the server.
# Create a new tiddler using the {{$:/core/images/new-button}} button in the sidebar on the right
# Click the {{$:/core/images/done-button}} button at the top right of the new tiddler
# Check the ~TiddlyWiki command line for a message confirming the tiddler has been saved
# Refresh the page in the browser to and verify that the new tiddler has been correctly saved
