+# Developer Certificate of Origin (DCO)
+In order to contribute to the project, you must agree to the Developer Certificate of Origin. A [Developer Certificate of Origin (DCO)](https://developercertificate.org/)
+is an affirmation that the developer contributing the proposed changes has the necessary rights to submit those changes.
+A DCO provides some additional legal protections while being relatively easy to do. 
+
+The entire DCO can be summarized as:
+- Certify that the submitted code can be submitted under the open source license of the project (e.g. MIT)
+- I understand that what I am contributing is public and will be redistributed indefinitely
+
+
+## How to Use Developer Certificate of Origin
+In order to contribute to the project, you must agree to the Developer Certificate of Origin. To confirm that you agree, your commit message must include a Signed-off-by trailer at the bottom of the commit message. 
+
+For example, it might look like the following:
+```bash
+A commit message
+
+Closes gh-345
+
+Signed-off-by: jane marmot <jmarmot@example.org>
+```
+
+The Signed-off-by [trailer](https://git-scm.com/docs/git-interpret-trailers) can be added automatically by using the [-s or –signoff command line option](https://git-scm.com/docs/git-commit/2.13.7#Documentation/git-commit.txt--s) when specifying your commit message:
+```bash
+git commit -s -m
+```
+If you have chosen the [Keep my email address private](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-email-preferences/setting-your-commit-email-address#about-commit-email-addresses) option within GitHub, the Signed-off-by trailer might look something like:
+```bash
+A commit message
+
+Closes gh-345
+
