image-tools is a collection of tools for working with the OCI image format specification.
Development happens on GitHub. Issues are used for bugs and actionable items and longer discussions can happen on the mailing list.

Discuss your design
The project welcomes submissions, but please let everyone know what you are working on.
Before undertaking a nontrivial change to this repository, send mail to the mailing list to discuss what you plan to do. This gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits. It also guarantees that the design is sound before code is written; a GitHub pull-request is not the place for high-level discussions.
Typos and grammatical errors can go straight to a pull-request. When in doubt, start on the mailing-list.
The contributors and maintainers of all OCI projects have a weekly meeting Wednesdays at 2:00 PM (USA Pacific.) Everyone is welcome to participate via UberConference web or audio-only: 888-587-9088 or 860-706-8529 (no PIN needed.) An initial agenda will be posted to the mailing list earlier in the week, and everyone is welcome to propose additional topics or suggest other agenda alterations there. Minutes are posted to the mailing list and minutes from past calls are archived to the wiki for those who are unable to join the call.
You can subscribe and join the mailing list on Google Groups.
OCI discussion happens on #opencontainers on Freenode (logs).
Sign your work
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):
Developer Certificate of Origin Version 1.1 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 660 York Street, Suite 102, San Francisco, CA 94110 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
then you just add a line to every git commit message:
Signed-off-by: Joe Smith <firstname.lastname@example.org>
using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the sign off when creating the git commit via
git commit -s.
