-The contributions must be Github pull requests.
-It is also possible to send contributions as email patches. But please be aware
-that the review process might take significantly longer than in the case of
-Github pull requests. You can submit your email patches to the
-lxc-devel@lists.linuxcontainers.org mailing list. (Use
-http://lists.linuxcontainers.org/listinfo/lxc-devel to subscribe to the list.)
-The guidelines for submitting email patches are the same as the patch submission
-for the Linux kernel except for the DCO which is defined below. The guidelines
-are defined in the 'SubmittingPatches' file, available in the directory
-'Documentation' of the Linux kernel source tree:
-https://www.kernel.org/doc/html/v4.10/process/submitting-patches.html
