 ## Unreleased
 ### Added
-- Nested tag support - "parent/child" tags used with the "Tag" hierarchy create nested folders.
+- Nested tag support (Issue [#85](https://github.com/out-of-cheese-error/gooseberry/issues/85))
+  - `gooseberry config kb nested` and `nested_tag` config option to determine pattern to use for nesting tags.
+  - `parent<nested_tag>child` tags used with the "Tag" hierarchy create nested folders.
 - Separate make and index commands, allow filtering annotations in both (
   Issue [#90](https://github.com/out-of-cheese-error/gooseberry/issues/90))
 - Better and more filtering options (Issue [#92](https://github.com/out-of-cheese-error/gooseberry/issues/92))

+#### Tags and nesting
+
+`gooseberry config kb nested`
+
+This defines the pattern to use for nesting tags. e.g. if `nested_tag = "/"` then a tag of "parent/child" combined
+with `hierarchy = ["Tag"]` would create a "parent" folder with a "child" file inside it.
+
+Commas (",") and semicolons (";") should not be used inside tags as they are used as separators by Gooseberry.
 
 #### Index link template
 
 `gooseberry config kb link`
 
 This configures the index file, which generally contains links to all other pages in the generated knowledge base
-(unless `hierarchy=[]` in which case all annotations are rendered on the index page). The template controls how each of these links are rendered.
