Development on MCUboot primarily takes place in github, at: https://github.com/mcu-tools/mcuboot
Changes should be submitted via github pull requests. Each commit should have a Signed-off-by line for the author (and the committer, if that is different). It is not necessary (or possible) to get a Signed-off-by from Github itself, even though some commits may be generated by that tool.
The Signed-off-by line should be at the end of the commit text, in the last blank-line-separated section. There can be multiple lines in this section (the format being roughly like RFC-2822). Currently supported trailer lines are:
Signed-off-by: Developer Name <firstname.lastname@example.org>
which indicates that the signer agrees to the Developer Certificate of Origin below, and
which associates this commit with a particular JIRA ticket. You can put more than one JIRA ticket, by separating them with a comma and a space. JIRA is quite flexible about where the indicators go, but putting them in a trailer with a common format will make them easier to find later.
