+### Ignore Scheme
+
+*Default: []*
+
+With this option you can ignore documents with a specific scheme. An item has to match the case-sensitive string of the scheme of the document. For instance, if you want to ignore VSCode output windows:
+
+``` js
+// documents with the scheme "output" are ignored
+{ "trailing-spaces.schemeIgnore": ["output"]}
+```
