All of the Lessons (in ebook format and streaming HD video)
Location-Based Pricing. I totally get that in some countries salaries and cost of living are such that the the guides are unaffordable. These should show up automatically at checkout, but if they don't, send me an email at firstname.lastname@example.org, and I'll send you a discount to make it fair for where you live.
If I buy just one guide and love it, can I upgrade to the bundle?
I'll upgrade you to the bundle or format you want. You'll only have to pay the difference in price between what you purchased and the bundle or format you want.
How do I access my guides?
Visit and create an account with the email address you used to make your purchase.
You can download your guides in ebook format at any time, and stream your video courses from any device. You can also download the videos for offline viewing.
Do I need any special tools or equipment?
All you need to work with the source code and projects is a modern web browser and a text editor (I recommend VS Code). The pocket guides come in PDF, EPUB, MOBI, and HTML formats, so you can read it on any device you own. The videos can be streamed on any device.
Are there any rules or requirements around the Slack team?
Yes. You must be at least 18 years old, and read and agree to follow the Code of Conduct.
Do you have a return policy?
Absolutely! If you’re not 100% satisfied with the guides, email me at email@example.com and I’ll give you a full refund.
