# Reference

The content in the reference section assumes an intermediate level of proficiency with both Bubble and the Canvas system and contains detailed reference materials on the [Canvas Base Template](https://bubble.io/template/canvas-starter-template-1541110863579x114287102114398200).

If you want to extend the app in more complex ways than outlined in the previous sections, or understand each page's function in more detail, read through this section.
