+      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

+          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

+          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

+          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.
+

+# Maps Booking
+
+This repo contains tools and code samples for partners that wish to integrate
+with [Reserve](https://www.google.com/maps/reserve/)
+
+## Testing Client
+
+Before using the test utility, the Go programming language must be installed
+on your workstation. A precompiled Go binary for your operating system can
+be [found here](https://golang.org/dl/)
+
+This guide will assume you're using the default GOPATH and subsequent GOBIN.
+For a comprehensive explanation of the GOPATH env variable please see
+[this document](https://golang.org/dl/) by the Go team.
+
+### Installing the utility
+
+First, build your Go directory structure. A comprehensive guide on the intended
+structure of Go code can be [found here.](https://golang.org/doc/code.html)
+
+    mkdir -p $HOME/go/bin $HOME/go/pkg $HOME/go/src/github.com/maps-booking
+
+Next, retrieve the utility from the
+[maps-booking repository](https://maps-booking.googlesource.com/)
+
+    git clone https://maps-booking.googlesource.com/test_client $HOME/go/src/github.com/maps-booking/
+
+Lastly, download all dependencies and install the tool.
+
+    go get -d $HOME/go/...
+    go install $HOME/go/src/github.com/maps-booking/testclient/main.go
+
+### Using the utility
+
+After following the install steps above an executable should now live in
+
+    $HOME/go/bin/main
+
+All available flags can be displayed using the '--help' flag. The currently
+accepted flags are:
+
+    -all_tests
+        Whether to test all endpoints.
+    -availability_feed string
+        Absolute path to availability feed required for all tests except health.
+        Feeds can be in either json or pb3 format
+    -booking_status_test
+        Whether to test the GetBookingStatus endpoint.
+    -booking_test
+        Whether to test the CreateBooking endpoint.
+    -check_availability_test
+        Whether to test the CheckAvailability endpoint.
+    -health_check_test
+        Whether to test the Health endpoint.
+    -list_bookings_test
+        Whether to test the ListBookings endpoint
+    -num_test_slots int
+        Maximum number of slots to test from availability_feed.
+        Slots will be selected randomly (default 10)
+    -output_dir string
+        Absolute path of dir to dump log file.
+    -rescheduling_test
+        Whether to test the UpdateBooking endpoint.
+    -rpc_timeout duration
+        Number of seconds to wait before abandoning request (default 30s)
+    -server_addr string
+        Your grpc server's address in the format of
+        host:port (default "example.com:80")
+
+Example Usage:
+
+    bin/main -health_check_test=true -check_availability_test=true
+    -output_dir="/tmp" -server_addr="localhost:50051”
+    -availability_feed="/tmp/test.json"
+
+### Parsing the output
+
+The test utility will output a file with the prefix 'grpc_test_client_log_'
+followed by a timestamp in RFC3339 format. The output file contains a
+complete log of all Requests and Responses sent/received by the testing tool as
+well as diffs of the expected response in the event of errors.
+Similar to a compiler, an overview of the entire run can be found at the end
+of the file for user friendly digestion.
