Might not be worth too much outside of Poland but here it is. My first book containing summary of tips and tricks used at work with WordPress.
It contains information about:
- how and which themes and plugins you should consider;
- how to secure your website;
- make and restore your perfect backup;
- manage SEO;
- run your own, professional newsletter;
- optimize your website for mobile devices;
- speed-up your WordPress
… and many more!
You can buy it online or as paperback thanks to „Komputer Świat” magazine.
