+# Lightpanda (Selecy SAS) Grant and Contributor License Agreement (“Agreement”)
+
+This agreement is based on the Apache Software Foundation Contributor License
+Agreement. (v r190612)
+
+Thank you for your interest in software projects stewarded by Lightpanda
+(Selecy SAS) (“Lightpanda”). In order to clarify the intellectual property
+license granted with Contributions from any person or entity, Lightpanda must
+have a Contributor License Agreement (CLA) on file that has been agreed to by
+each Contributor, indicating agreement to the license terms below. This license
+is for your protection as a Contributor as well as the protection of Lightpanda
+and its users; it does not change your rights to use your own Contributions for
+any other purpose. This Agreement allows an individual to contribute to
+Lightpanda on that individual’s own behalf, or an entity (the “Corporation”) to
+submit Contributions to Lightpanda, to authorize Contributions submitted by its
+designated employees to Lightpanda, and to grant copyright and patent licenses
+thereto.
+
+You accept and agree to the following terms and conditions for Your present and
+future Contributions submitted to Lightpanda. Except for the license granted
+herein to Lightpanda and recipients of software distributed by Lightpanda, You
+reserve all right, title, and interest in and to Your Contributions.
+
+1. Definitions. “You” (or “Your”) shall mean the copyright owner or legal
+   entity authorized by the copyright owner that is making this Agreement with
+   Lightpanda. For legal entities, the entity making a Contribution and all
+   other entities that control, are controlled by, or are under common control
+   with that entity are considered 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 percent (50%) or more of the
+   outstanding shares, or (iii) beneficial ownership of such entity.
+   “Contribution” shall mean any work, as well as any modifications or
+   additions to an existing work, that is intentionally submitted by You to
+   Lightpanda for inclusion in, or documentation of, any of the products owned
+   or managed by Lightpanda (the “Work”). For the purposes of this definition,
+   “submitted” means any form of electronic, verbal, or written communication
+   sent to Lightpanda or its representatives, including but not limited to
+   communication on electronic mailing lists, source code control systems (such
+   as GitHub), and issue tracking systems that are managed by, or on behalf of,
+   Lightpanda for the purpose of discussing and improving the Work, but
+   excluding communication that is conspicuously marked or otherwise designated
+   in writing by You as “Not a Contribution.”
+
+2. Grant of Copyright License. Subject to the terms and conditions of this
+   Agreement, You hereby grant to Lightpanda and to recipients of software
+   distributed by Lightpanda a perpetual, worldwide, non-exclusive, no-charge,
+   royalty-free, irrevocable copyright license to reproduce, prepare derivative
+   works of, publicly display, publicly perform, sublicense, and distribute
+   Your Contributions and such derivative works.
+
+3. Grant of Patent License. Subject to the terms and conditions of this
+   Agreement, You hereby grant to Lightpanda and to recipients of software
+   distributed by Lightpanda a perpetual, worldwide, non-exclusive, no-charge,
+   royalty-free, irrevocable (except as stated in this section) patent license
+   to make, have made, use, offer to sell, sell, import, and otherwise transfer
+   the Work, where such license applies only to those patent claims licensable
+   by You that are necessarily infringed by Your Contribution(s) alone or by
+   combination of Your Contribution(s) with the Work to which such
+   Contribution(s) were submitted. If any entity institutes patent litigation
+   against You or any other entity (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.
+
+4. You represent that You are legally entitled to grant the above license. If
+   You are an individual, and if Your employer(s) has rights to intellectual
+   property that you create that includes Your Contributions, you represent
+   that You have received permission to make Contributions on behalf of that
+   employer, or that Your employer has waived such rights for your
+   Contributions to Lightpanda. If You are a Corporation, any individual who
+   makes a contribution from an account associated with You will be considered
+   authorized to Contribute on Your behalf.
+
+5. You represent that each of Your Contributions is Your original creation (see
+   section 7 for submissions on behalf of others).
+
+6. You are not expected to provide support for Your Contributions,except to the
+   extent You desire to provide support. You may provide support for free, for
+   a fee, or not at all. Unless required by applicable law or agreed to in
+   writing, You provide Your Contributions on an “AS IS” BASIS, WITHOUT
+   WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including,
+   without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT,
+   MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
+
+7. Should You wish to submit work that is not Your original creation, You may
+   submit it to Lightpanda separately from any Contribution, identifying the
+   complete details of its source and of any license or other restriction
+   (including, but not limited to, related patents, trademarks, and license
+   agreements) of which you are personally aware, and conspicuously marking the
+   work as “Submitted on behalf of a third-party: [named here]”.
