Check it out on docs.junit.org!

Thanks to the @sovereign.tech agency for making it possible and to the @antora.org project for the excellent tool!

JUnit is undoubtedly one of the most important projects in the #Java ecosystem. And it's 100% free and open!

Let me be frank: If we can't get THIS project to the point where a single maintainer can focus on it, then what does that say about our commitment to Free & Open Source Software?
