# Building Blocks

- [Structure](/liquid/building-blocks/structure.md): Kajabi themes have a specific structure that can be utilized when creating or editing themes. Only this specific file structure will be included when a theme is uploaded to the system.
- [Layouts](/liquid/building-blocks/layouts.md): Layout files are very important for your theme because every other template file is rendered inside the active layout.
- [Sections](/liquid/building-blocks/untitled-1.md): Kajabi themes are built around the concept of sections and blocks. These building blocks can be used in various ways to compose any layout.
- [Section Types](/liquid/building-blocks/section-types.md): In Kajabi there are two types of sections, sections that the user can add to the page and sections that are pre loaded onto the page.
- [Blocks](/liquid/building-blocks/blocks.md): If you think of a section as a row then its columns are what kajabi calls blocks. Blocks are groupings of settings that can be added and removed from a section by the user.
