# Adding new templates

Please, if you haven’t first read this section <https://www.one.thezero.club/guide/theme-extending>

Because Zero One is a theme made as a plugin, you can override every plugin file with the same name and file in the site/theme folder. But it must be in the same folder structure as in the plugin.

#### Let’s say you want to add a new template called “books”:

* **Create a template first**
  * Add a new **`site/theme/blueprints/pages/books.yml`** file for the page blueprint
  * Then add a new **`site/theme/templates/books.php`** file for the template code
* **Include the template in the main pages** (main dashboard, highest level pages)
  * Copy **`site/plugins/zero-one/blueprints/tabs/site-content.yml`** file
  * To site/theme/blueprints/tabs/ folder (create blueprints and tabs folders, of course), so you get **`site/theme/blueprints/tabs/site-content.yml`** file
  * Open the file with the code editor and add the “books” template name in the allowed templates for both Draft templates and Published templates
  * And that’s it! Test it and you will see your new template.
* **Include the template to subpages:**
  * Copy **`site/plugins/zero-one/blueprints/sections/page-draft.yml`** file
  * To **`site/theme/blueprints/sections/`** folder (create folders), to get **`site/theme/blueprints/sections/page-draft.yml`** file
  * Open that new file and add the “books” template to the allowed templates list
  * Do the same with **`site/plugins/zero-one/blueprints/sections/page-published.yml`** file (copy it to, and change it like you did with **page-draft.yml** file)

When you follow this approach, even when you update Zero One to the new version, your changes will be untouched.

For the page template, we suggest you check:

* **`site/plugins/zero-one/blueprints/pages/default.yml`**
* And **`site/plugins/zero-one/templates/default.php`**

And maybe use that template as your base for further extension/customization.
