+
+`GOOGLE_CLOUD_CPP_ENABLE_TRACING=rpc`: turns on tracing for most gRPC
+calls. The library injects an additional Stub decorator that prints each gRPC
+request and response.  Unless you have configured your own logging backend,
+you should also set `GOOGLE_CLOUD_CPP_ENABLE_CLOG` to produce any output on
+the program's console.
+
+@see google::cloud::LoggingComponentsOption
+
+`GOOGLE_CLOUD_CPP_TRACING_OPTIONS=...`: modifies the behavior of gRPC tracing,
+including whether messages will be output on multiple lines, or whether
+string/bytes fields will be truncated.
+
+@see google::cloud::GrpcTracingOptionsOption
+
+`GOOGLE_CLOUD_CPP_ENABLE_CLOG=yes`: turns on logging in the library, basically
+the library always "logs" but the logging infrastructure has no backend to
+actually print anything until the application sets a backend or they set this
+environment variable.
+
+@see google::cloud::LogBackend
+@see google::cloud::LogSink
+
+@section saasservicemgmt-env-project Setting the Default Project
+
+`GOOGLE_CLOUD_PROJECT=...`: is used in examples and integration tests to
+configure the GCP project. This has no effect in the library.

+## Main classes
+
+<!-- inject-client-list-start -->
+This library offers multiple `*Client` classes, which are listed below. Each one
+of these classes exposes all the RPCs for a service as member functions of the
+class. This library groups multiple services because they are part of the same
+product or are often used together. A typical example may be the administrative
+and data plane operations for a single product.
+
+The library also has other classes that provide helpers, configuration
+parameters, and infrastructure to mock the `*Client` classes when testing your
+application.
