 The last set of values found is inserted at the beginning of the list.
 You can collect filters for all the imported global sections.
 
+Imports are processed recursively: An `import` section in an imported

 It's recommended to always use some file extension in the *FILE_CONTAINING_THE_YAML_DEFINITIONS* name.
 If you don't use any file extension and you use a relative path this name could be confused with an internal template.
 See [Importing internal templates](#importing-internal-templates).
