+The heap profiling service provides:
+  * Storage for recording metadata about heap allocations and deallocations,
+  for any number of clients.
+  * A lightweight, synchronous API for clients to send metadata about heap
+  allocations and deallocations.
+
+There are two main entities:
+  * Heap Profiling Clients send heap allocation data to the Heap Profiling
+    Service. Clients require no special privileges. There should be at most 1
+    Client per process, since heap hooks are instantiated on a per-process
+    basis.
+  * The Heap Profiling Service runs in an unprivileged, sandboxed process. It's
+    sole purpose is to record allocations and serve them in heap dumps.
+
+Heap dumps are emitted in traces with the "memory-infra" category enabled. This
+is coordinated by the (memory_instrumentation
+service)[https://cs.chromium.org/chromium/src/services/resource_coordinator/public/mojom/memory_instrumentation/memory_instrumentation.mojom].
+See the HeapProfiler and HeapProfilerHelper interfaces.
