As a web-adjacent developer, you deal with domain names all day long. Sometimes
they're humming along in the background and you can ignore them. Other times,
adding a domain record doesn't propagate and you don't know why or how to fix
it.

To complicate matters, a secure domain is not only important to your customers'
safety, but it's often a cost of doing business. TLS certificates are a great
thing for the internet at large, but understanding how they work is _daunting_.
Not to mention having to buy and set up a TLS certificate for your own website.

**You're in luck! I am excited to announce that my new book: [Domain Name
Sanity](http://domainnamesanitybook.com/) is available for purchase today!**

[Domain Name Sanity](http://domainnamesanitybook.com/) clarifies domains and
makes their behavior predictable and debuggable. This book includes the tools
and information you need to set up, maintain, and troubleshoot any domain. It
even describes how to set up a TLS certificate from scratch.

Domain Name Sanity is written in an informal, conversational style, as if we’re
talking while sitting in comfortable chairs. This is not another boring
technical manual or RFC, promise.

When you purchase the book, you'll get access to the GitHub repository and all
future updates I might write. [Head on over](http://domainnamesanitybook.com/)
