+## Developer Certification of Origin (DCO)
+To make a good faith effort to ensure licensing criteria are met, ASAM open source projects require the Developer Certificate of Origin (DCO) process to be followed.
+
+The DCO is an attestation attached to every contribution made by every developer. In the commit message of the contribution, (described more fully later in this document), the developer simply adds a Signed-off-by statement and thereby agrees to the DCO.
+
+When a developer submits a patch, it is a commitment that the contributor has the right to submit the patch per the standard license. The DCO agreement is shown below and online.
+
+    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.
+
+## DCO Sign-Off Methods
+The DCO requires a sign-off message in the following format appear on each commit in the pull request:
+```
+Signed-off-by: Firstname Lastname <email@address.com>
+```
+The DCO text can either be manually added to your commit body, or you can add either `-s` or `--signoff` to your usual Git commit commands. If you forget to add the sign-off you can also amend a previous commit with the sign-off by running `git commit --amend -s`. You can add sign-offs to multiple commits (including commits originally authored by others, if you are authorized to do so) using `git rebase --signoff`. If you’ve pushed your changes to GitHub already you’ll need to force push your branch after this with `git push --force-with-lease`.
+
+If you want to be reminded to add the sign-off for commits in your repository, you can add the following commit-message git hook to your repository:
+
+```shell
+    #!/bin/sh
+    #
+    # Check for DCO/Signed-off-by in message
+    #
+
+    if ! grep -q "^Signed-off-by: " "$1"
+    then
+    echo "Aborting commit: Commit message is not signed off" >&2
+    exit 1
+    fi
+```
+
+Placing this script into a file called `.git/hooks/commit-msg` and making it executable (e.g. using `chmod a+x .git/hooks/commit-msg` on unixoid operating systems) will prevent commits that do not have a sign-off.
