 Diagrams is a Phorge extension application for
 [[ https://www.drawio.com | diagrams.net (previously draw.io)]] by JGraph.
 
 You can create and store diagrams in your Phorge instance.
 These diagrams can be referenced by means of the `DIAG` token.
 For example: `{DIAG123}`.
 
 When you double click on a diagram, the editor will open the corresponding
 diagram in a new browser tab.
 
 You can create diagrams with multiple pages, but only the first one will be
 visualized in a referenced diagram.
 
 When you modify an existing diagram, a new version will be created.
 You can select older versions in the editor by means of the dropdown in the
 topright corner.
-If you don't see a dropdown, you diagram has only 1 version.
+If you don't see a dropdown, your diagram has only 1 version.
