+# This pipeline deploys the test servers we are using to run (outerloop) Functional tests for various functionality in System.Net namespace.
+# The pipeline deploys to staging slots, which are available at
+# - corefx-net-http11-staging.azurewebsites.net
+# - corefx-net-http2-staging.azurewebsites.net
+#
+# Usage instructions:
+# 1) Start pipeline at https://dev.azure.com/dnceng/internal/_build?definitionId=1419 (
+deploy-networking-echo-test-servers), pick the correct branch and start the build.
+# 2) After pipeline succeeds, check your changes against the staging slots, two possible ways to do this are:
+#   - create a no-merge PR where you overwrite the default urls (e.g. https://github.com/dotnet/runtime/pull/111396)
+#   - test locally, either by same changes as in above PR, or by using the override environment variables
+#
+#     DOTNET_TEST_HTTPHOST=http://corefx-net-http11-staging.azurewebsites.net
+#     DOTNET_TEST_SECUREHTTPHOST=https://corefx-net-http11-staging.azurewebsites.net
+#     DOTNET_TEST_WEBSOKETHOST=http://corefx-net-http11-staging.azurewebsites.net
+#     DOTNET_TEST_SECUREWEBSOKETHOST=http://corefx-net-http11-staging.azurewebsites.net
+#
+#     DOTNET_TEST_HTTP2HOST=http://corefx-net-http2-staging.azurewebsites.net
+# 3) If there are no issues, you can swap the staging slots with production slots via the Azure portal.
+#    Only the members of the .NET Networking team have access to the Azure Subscription which hosts the
+#    servers. Look for the "Deployment slots" section at corefx-net-http11 and corefx-net-http2 Web Apps
