+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,

+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its 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. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+Build
+=====
+
+This @PLUGIN@ plugin is built with Bazel.
+
+Clone (or link) both this plugin and also
+[plugins/its-base](https://gerrit-review.googlesource.com/#/admin/projects/plugins/its-base)
+to the `plugins` directory of Gerrit's source tree.
+
+Put the external dependency Bazel build file into the Gerrit /plugins directory,
+replacing the existing empty one.
+
+```
+  cd gerrit/plugins
+  rm external_plugin_deps.bzl
+  ln -s @PLUGIN@/external_plugin_deps.bzl .
+```
+
+Then issue
+
+```
+  bazel build plugins/@PLUGIN@
+```
+
+in the root of Gerrit's source tree to build
+
+The output is created in
+
+```
+  bazel-genfiles/plugins/@PLUGIN@/@PLUGIN@.jar
+```
+
+This project can be imported into the Eclipse IDE.
+Add the plugin name to the `CUSTOM_PLUGINS` set in
+Gerrit core in `tools/bzl/plugins.bzl`, and execute:
+
+```
+  ./tools/eclipse/project.py
+```
+
+To execute the tests run:
+
+```
+  bazel test plugins/@PLUGIN@
+```

+Phabricator connectivity
+========================
+
+In order for @PLUGIN@ to connect to your Phabricator instance, url (without
+trailing “/api”, “/conduit” or some such), user, and certificate are required in
+your site's `etc/gerrit.config` or `etc/secure.config` under the `@PLUGIN@`
+section.
+
+Example:
+
+```
+[@PLUGIN@]
+  url = http://my.phabricator.instance.example.org
+  token = TOKEN_FOR_ABOVE_USERNAME
+```
+
+You can get your token by going to http://my.phabricator.instance.example.org/conduit/login/

+@PLUGIN@-specific actions
+=========================
+
+In addition to the [basic actions][basic-actions], @PLUGIN@ also
+provides:
+
+[`add-project`][action-add-project]
+: adds a project to the task
+
+[`remove-project`][action-remove-project]
+: removes a project from the task
+
+[basic-actions]: config-rulebase-common.html#actions
+
+[action-add-project]: #action-add-project
+### <a name="action-add-project">Action: add-project</a>
+
+The `add-project` action adds a project to the task. The first
+parameter is the project name to add. So for example
+
+```
+  action = add-project MyCoolProject
+```
+
+adds the project `MyCoolProject` to the task.
+
+[action-remove-project]: #action-remove-project
+### <a name="action-remove-project">Action: remove-project</a>
+
+The `remove-project` action removes a project from the task. The first
+parameter is the project name to remove. So for example
+
+```
+  action = remove-project MyCoolProject
+```
+
+removes the project `MyCoolProject` from the task.
