+# Contents of the boilerplate
+
+- `app.py` the flask webapp, generating the views
+- `pagedjs.py` helper functions to run pagedjs-cli from python
+- `utils.py` utitilities for generative books
+- `templates/index.html` template for the index
+- `templates/book.html` template for the book itself
+- `static/style.css` css style rules for the index and book (it's possible to split them up, also adjust the templates then)
+- `static/pagedjs.interface.css` css style rules provided by paged.js to have a more rich preview in debug mode
+
+# Usage
+
+The boilerplate essentially has two views: `index` and `generate`. The `index` shows the homepage and a link to the  `generate` function. In this example the generated book is downloaded as a PDF.
+
+The template `templates/book.html` is used with styles from `static/style.css` to generate the PDF, adjust them to adjust your book. In `app.py` the function generate loads the template, adjust that function to generate context and / or HTML.
+
+In the [documentation of paged.js](https://pagedjs.org/documentation/) a lot of information on print specific functionality in CSS can be found.
