+We are incredibly thankful for the contributions we receive from the community.

+We require our external contributors to sign a Contributor License Agreement ("CLA") in
-referred to as "NetBird" (collectively, the "Parties"). The Agreement outlines the terms and conditions 
+order to ensure that our projects remain licensed under Free and Open Source licenses such
-under which NetBird may utilize software contributions provided by the Contributor for inclusion in 
+as BSD-3 while allowing NetBird to build a sustainable business.
-its software development projects. By submitting this Agreement, the Contributor confirms their acceptance 
+
-of the terms and conditions outlined below. The Contributor further represents that they are authorized to 
+NetBird is committed to having a true Open Source Software ("OSS") license for

+our software. A CLA enables NetBird to safely commercialize our products
+while keeping a standard OSS license with all the rights that license grants to users: the
+ability to use the project in their own projects or businesses, to republish modified
+source, or to completely fork the project.
+
+This page gives a human-friendly summary of our CLA, details on why we require a CLA, how
+contributors can sign our CLA, and more. You may view the full legal CLA document (below).
+
+# Human-friendly summary
+
+This is a human-readable summary of (and not a substitute for) the full agreement (below).
+This highlights only some of key terms of the CLA. It has no legal value and you should
+carefully review all the terms of the actual CLA before agreeing.
+
+<li>Grant of copyright license. You give NetBird permission to use your copyrighted work
+in commercial products.
+</li>
+
+<li>Grant of patent license. If your contributed work uses a patent, you give NetBird a
+license to use that patent including within commercial products. You also agree that you
+have permission to grant this license.
+</li>
+
+<li>No Warranty or Support Obligations.
+By making a contribution, you are not obligating yourself to provide support for the
+contribution, and you are not taking on any warranty obligations or providing any
+assurances about how it will perform.
+</li>
+
+The CLA does not change the terms of the standard open source license used by our software
+such as BSD-3 or MIT.
+You are still free to use our projects within your own projects or businesses, republish
+modified source, and more.
+Please reference the appropriate license for the project you're contributing to to learn
+more.
+
+# Why require a CLA?
+
+Agreeing to a CLA explicitly states that you are entitled to provide a contribution, that you cannot withdraw permission
+to use your contribution at a later date, and that NetBird has permission to use your contribution in our commercial
+products.
+
+This removes any ambiguities or uncertainties caused by not having a CLA and allows users and customers to confidently
+adopt our projects. At the same time, the CLA ensures that all contributions to our open source projects are licensed
+under the project's respective open source license, such as BSD-3.
+
+Requiring a CLA is a common and well-accepted practice in open source. Major open source projects require CLAs such as
+Apache Software Foundation projects, Facebook projects (such as React), Google projects (including Go), Python, Django,
+and more. Each of these projects remains licensed under permissive OSS licenses such as MIT, Apache, BSD, and more.
+
+# Signing the CLA
+
+Open a pull request ("PR") to any of our open source projects to sign the CLA. A bot will comment on the PR asking you
+to sign the CLA if you haven't already.
+
+Follow the steps given by the bot to sign the CLA. This will require you to log in with GitHub (we only request public
+information from your account) and to fill in a few additional details such as your name and email address. We will only
+use this information for CLA tracking; none of your submitted information will be used for marketing purposes.
+
+You only have to sign the CLA once. Once you've signed the CLA, future contributions to any NetBird project will not
+require you to sign again.
+
+# Legal Terms and Agreement
+
+In order to clarify the intellectual property license granted with Contributions from any person or entity, NetBird
+GmbH ("NetBird") must have a Contributor License Agreement ("CLA") on file that has been signed
+by each Contributor, indicating agreement to the license terms below. This license does not change your rights to use
+your own Contributions for any other purpose.
+
+You accept and agree to the following terms and conditions for Your present and future Contributions submitted to
+NetBird. Except for the license granted herein to NetBird and recipients of software distributed by NetBird,

+   to be a single Contributor. For the purposes of this definition, "control" means (i) the power, direct or indirect,
+    to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty

+   an existing work, that is or previously has been intentionally submitted by You to NetBird for inclusion in, 
+   or documentation of, any of the products owned or managed by NetBird (the "Work"). 
+   For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication 
+   sent to NetBird or its representatives, including but not limited to communication on electronic mailing lists,

+   marked or otherwise designated in writing by You as "Not a Contribution."

+   including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have
+   contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity
+   under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
