Questions about Publii
For my website I used the Starter theme and I haven’t updated it yet. I also think that I’m not going to that, why would I?
Do you have created a separate directory that contains all the customization of your website? If you override the most important files, an update of a theme shouldn’t have that much of an impact.
When my website is finished (which I’m making for someone I know) I could send you the code? Just give me your e-mail address and I will send it to you!
