* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-uuid)
* [Report bugs](https://github.com/boostorg/uuid/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).
* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[uuid]` tag at the beginning of the subject line.
