Your source publication needs a license. In the US, if no license isspecified, users have no legal right to download, modify, or distribute.Furthermore, people can’t contribute to your code unless you tell them whatrules to play by. Choosing a license is complicated, so here are some pointers:

Open source. There are plenty of open source licenses available to choosefrom.

In general, these licenses tend to fall into one of two categories:

  • licenses that focus more on the user’s freedom to do with thesoftware as they please (these are the more permissive opensource licenses such as the MIT, BSD, and Apache)
  • licenses that focus more on making sure that the code itself —including any changes made to it and distributed along with it —always remains free (these are the less permissive free softwarelicenses such as the GPL and LGPL)
    The latter are less permissive in the sense that they don’t permitsomeone to add code to the software and distribute it without alsoincluding the source code for their changes.

To help you choose one for your project, there’s a license chooser;use it.
