&lt;p&gt;I would highly appreciate if you&#x27;d &lt;strong&gt;let me know how you felt about this book&lt;&#x2F;strong&gt;. It could be anything from a simple thank you, Gumroad rating, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn&#x27;t!) and so on. Reader feedback is essential and especially so for self-published authors.&lt;&#x2F;p&gt;
