- pages parameters has been deprecated and renamed by nav - the build fails with an empty extra_css array
Fixes #1177 The `url` template filter is [only supported in Mkdocs 1.0+](https://github.com/mkdocs/mkdocs/blob/master/docs/about/release-notes.md#internal-refactor-of-pages-files-and-navigation) Readthedocs.org uses Mkdocs `0.17.3 ` while `make htmldoc` fetches the [latest version from pypi](https://pypi.org/project/mkdocs/) which is `1.0.4`. Following https://github.com/shaarli/Shaarli/pull/1220, building the docs fails with https://readthedocs.org/projects/shaarli/builds/7886340/
- Customize the "readthedocs" mkdocs theme: https://www.mkdocs.org/user-guide/styling-your-docs/#customizing-a-theme - Adds a '<meta name="robots" content="noindex, nofollow">' HTML tag on each page - Do not include robots directive on readthedocs.org, only in local builds
