+#* You may rename it, but be sure to keep the `.html` extension
+# Open the file in Internet Explorer
+# Try creating a new tiddler using the ''plus'' {{$:/core/images/new-button}} button in the sidebar. Type some content for the tiddler, and click the {{$:/core/images/done-button}} ''tick'' button
+# Save your changes by clicking the {{$:/core/images/save-button}} ''download'' button in the sidebar. Internet Explorer will ask for your consent to save the file locally by presenting a file ''Save As'' dialog.
