+# See the pRPC spec here: https://godoc.org/github.com/luci/luci-go/grpc/prpc
+#
+# Each Servicer corresponds to a service defined in a .proto file in this
+# directory. Each method on that Servicer corresponds to one of the rpcs
+# defined on the service.
+#
+# All APIs are served under the /prpc/* path space. Each service gets its own
+# namespace under that, and each method is an individual endpoints. For example,
+# POST https://bugs.chromium.org/prpc/monorail.v3.Issues/GetIssue
+# would be a call to the api.v3.issues_servicer.IssuesServicer.GetIssue method.
+#
+# Note that this is not a RESTful API, although it is CRUDy. All requests are
+# POSTs, all methods take exactly one input, and all methods return exactly
+# one output.
+#
+# TODO(http://crbug.com/monorail/1703): Actually integrate the rpcexplorer.
+# You can use the API Explorer here: https://bugs.chromium.org/rpcexplorer
