Hi, yes, no :) You can do whatever you want when using Inkscape, create books, courses or tutorials, etc. The main things you /cannot/ do is modify the source code of the program without respecting the license, or use the Inkscape name and/or logo to try to impersonate the project itself, but apart from those, you're /free//as in freedom/ :) And if you create nice stuff to promote Inkscape and its uses, you can tell us about it, we like to know which resources exist around it ☺ -- Marc On 11/27/21 2:59 PM, Luthfi Ahmad Robbaniy wrote:
