RM manages GPU resources via NVOC classes; the README now briefly enumerates the key resource categories and points to the generated class list for details.

• Resource overview: Added an English section summarizing RM-managed resources (root/device hierarchy, memory/mapping, address spaces, channels/engines, display/multimedia, sync/events, debug/perf/telemetry, virtualization/security) with exact line anchors into src/nvidia/generated/g_allclasses.h.
• Navigation aid: Highlights the generated class list as the authoritative source for RM resource handles.

Example excerpt:

## Resource Manager (RM) managed resource types overview
- Root/client sessions and device hierarchy: NV01_ROOT … NV2082_BINAPI_PRIVILEGED (lines 36–44)
- Memory and mapping objects: NV01_MEMORY_SYSTEM … NV_MEMORY_MULTICAST_FABRIC (lines 47–69)
- Address spaces: NV01_CONTEXT_DMA (46), FABRIC_VASPACE_A (68), IO_VASPACE_A (70), FERMI_VASPACE_A (167)
