 - For each filter, it sets output variable named by the filter to the text:
-   - `'true'` - if **any** of changed files matches any of filter rules
-   - `'false'` - if **none** of changed files matches any of filter rules
+  - `'true'` - if **any** of changed files matches any of filter rules
+  - `'false'` - if **none** of changed files matches any of filter rules
 - For each filter, it sets an output variable with the name `${FILTER_NAME}_count` to the count of matching files.
 - If enabled, for each filter it sets an output variable with the name `${FILTER_NAME}_files`. It will contain a list of all files matching the filter.
 - `changes` - JSON array with names of all filters matching any of the changed files.
