What licenses mean
MIT, Apache 2.0 and referral only, in plain words.
A license is the short text in which the author of a skill says "you may use this under these conditions". Skills are published for free, but they still belong to their authors. The license decides what you and we may do with a skill.
You will see two licenses most often in the catalog: MIT and Apache 2.0. Both are open licenses. They let you use the skill, copy it, change it and use it at work. In return they ask for one basic thing: the author's name and the license text stay with the copy.
MIT is the shortest, only a few paragraphs. Apache 2.0 is longer and adds two points: it says the author opens the related patent rights to whoever uses the skill, and it asks that changed files be marked. If you only install and use a skill, the difference between the two hardly affects you.
Both licenses offer the skill as it is. In other words, the author gives no guarantee that it will work correctly in every case. This is how most openly licensed software works.
Some skills have no license, or their license information contradicts itself. Without a license the author has not given permission to copy, so we do not copy and distribute that skill. In the catalog we mark these as "referral only". When you choose such a skill, the setup downloads it straight from the author's own source, not through us.
Skillducks does three things about licenses. It checks the license of every skill at its source, one by one. It keeps the author's name and the license text during setup. It shows the license type next to the skill, so you see it before you install.
Know this as well: the license covers the skill itself. Parts inside a skill, such as a font or an image, may be under separate rights. An extra program that a skill uses also carries its own license. If your company has rules about software, it is a good idea to share the skill's license and requirements with the person in charge.
What you pay for is not the skill. Skills are published for free. The fee you pay Skillducks is for selection, scanning, easy setup and staying current.
