I wrote a library that I'd like to make publicly available, so people can easily use it with gradle/maven/ect. However I am completely lost with what i need to do now. I looked into MavenCentral/JCenter/Bintray but they all seem to assume that I am part of some organization, which I'm not. I also don't have a website so I don't even know what I should use as my "group id". can someone help me get started?
