+===== Primary and alternative (sub)sections =====
 Note that some subsections could fall under more than one section (i.e., "alcohol use" could be seen as a subsection of "lifestyle" or of "nutrition", and "mental illness" could fall under "diseases & symptoms" or "mental health"). Similarly, individual variables may fit in more than one subsection.
-Lifelines __always asigns a primary section and subsection to a variable__, but may asign a secondary section and/or subsection to facilitate the findability of the variable in the online data catalogue.
+Lifelines __always asigns a primary section and subsection to a variable__, but may asign a second, alternative (sub)section to facilitate the findability of the variable in the online data catalogue.
+\\
+===== Default variables =====
+Some Lifelines variables are provided by default in every issued dataset. As a result, these variables are not visible in the data-catalogue. An overview of the default variables can be found [[default_variables|here]].
+\\
+===== Changes in variable names =====
+Note that we may occasionally change a variable name, if there is a valid reason to do so (i.e. the original name is deemed confusing, too informal, unexpected, inconsistent, or incorrect). You may find a full list of changed variable names following this link: [[changed variable names]].
+\\
+===== Unfixable variables =====
+Seldomly, we find variables that contain mistakes or inconsistencies. Most of the time these mistakes or inconsistencies will be corrected, but not always. You may find a full list of unfixable variables following this link: [[unfixable variables]].
