 ## Usage

 ```bash

+including how many words in each chapter are tagged with which status
+* -a or --act — output act-by-act breakdown of word counts (total only)

+### Comments
+
+Comments, such as outlining notes for yourself, can be added anywhere using:
+
+```yaml

+
+These words will not count towards the word count
+
+
+### Multi-file support
+
+Splitting your novel into multiple files is supported using the `MarkdownPP`
+python library. To include a secondary file inside the main one, simply use
+
+```yaml
+!INCLUDE "OtherFile.md"
+```
+
+and add the `-pp` flag to novel-stats.
