OpenSearch is a community project that is built and maintained by people just like you. This document explains how you can contribute to this and related projects.
OpenSearch is an open source product released under the Apache 2.0 license (see either the Apache site or the LICENSE.txt file). The Apache 2.0 license allows you to freely use, modify, distribute, and sell your own products that include Apache 2.0 licensed software.
We respect intellectual property rights of others and we want to make sure all incoming contributions are correctly attributed and licensed. A Developer Certificate of Origin (DCO) is a lightweight mechanism to do that.
The DCO is a declaration attached to every contribution made by every developer. In the commit message of the contribution, the developer simply adds a Signed-off-by statement and thereby agrees to the DCO, which you can find below or at DeveloperCertificate.org.
