 ### Title should not contain pagination macros
 There is no need to include the pagination title macros `:num`, `:max` or `:title` in the title configuration. The autopages will use the title configuration from the pagination configuration itself.
 
+### Categories and tags with spaces
+If you have category or tag names with spaces, make sure you use either
+1. the singular forms (`tag`, `category`), or
+2. the plural forms (`tags`, `categories`) using the YAML array syntax.

+See [Filtering categories](https://github.com/sverrirs/jekyll-paginate-v2/blob/master/README-GENERATOR.md#filtering-categories) for more information.

 > To define categories you can either specify them in the front-matter or through the [directory structure](http://jekyllrb.com/docs/variables/#page-variables) of your jekyll site (Categories are derived from the directory structure above the \_posts directory). You can actually use both approaches to assign your pages to multiple categories.

 > When specifying tags in your posts make sure that the values are not enclosed in single quotes (double quotes are fine). If they are you will get a cryptic error when generating your site that looks like _"Error: could not read file <FILE>: did not find expected key while parsing a block mapping at line 2 column 1"_
