+[Test Execution](https://github.com/googleapis/cloud-bigtable-clients-test#test-execution)
+for the Test Frameworks to see usage steps.
+
+## Running the test proxy
+
+1. Open a command terminal at the root of the Bigtable client library.
+
+1. Run the test proxy (this)
+
+
+        go run internal/testproxy/proxy.go
+

+flag:
