Side menu update in Nextcloud Pico CMS

I have a question about side menu or top menu.

After creating a website there are menus on the top of the page (default theme with sample_pico template) or in another theme on the left side.

When I create new websites (.md files) I can reach them from the URL but they do not appear in the main site menu.

Do I have to do something to refresh the list of menu items?


After some trial and error and reading theme descriptions I realized that each page (.md file) has to have a Title in the YAML header between the 3 — dashes

Then it works
