 ## `linked` (array of package names)
 
 This option can be used to declare that packages should 'share' a version, instead of being versioned completely independently. As an example, if you have a `@changesets/button` component and a `@changesets/theme` component and you want to make sure that when one gets bumped to `2.0.0`, the other is also bumped to `2.0.0`. To achieve this you would have the config:

+## Using glob expressions
+
+Sometimes you want to link many or all packages within your project (for example in a monorepository setup), in which case you would need to keep the list of linked packages up-to-date.
+
+To make it simpler to maintain that list, you can provide glob expressions in the linked list that would match and resolve to all the packages that you wish to include.
+
+For example:
+
+```json
+{
+  "linked": [["pkg-*"]]
+}
+```
+
+It will match all packages starting with `pkg-`.
+
+**The glob expressions must be defined according to the [micromatch](https://www.npmjs.com/package/micromatch) format.**
