+# Meshtastic Protocol Buffers Generation
+
+This internal package manages the generation of Go types from the [official Meshtastic protocol buffer definitions](https://github.com/meshtastic/protobufs).
+
+## Upstream Source
+
+The protobuf definitions are included as a git submodule at:
+
+```
+protocol/meshtastic/internal/pbgen/upstream
+```
+
+Tracked repository: `https://github.com/meshtastic/protobufs.git`
+
+## Generating Go Code
+
+To regenerate the Go protobuf types after updating the submodule:
+
+```bash
+# Update the submodule to latest (optional)
+git submodule update --remote protocol/meshtastic/internal/pbgen/upstream
+
+# Regenerate Go code
+go generate ./protocol/meshtastic/internal/pbgen
+```
+
+### Requirements
+
+- `protoc` (Protocol Buffers compiler)
+- `protoc-gen-go` (install via `go install google.golang.org/protobuf/cmd/protoc-gen-go@latest`)
+
+## Generated Package
+
+Generated Go types are placed in:
+
+```
+protocol/meshtastic/pb/
+```
+
+Import path:
+
+```go
+import meshtasticpb "git.maze.io/go/ham/protocol/meshtastic/pb"
+```
+
+All Meshtastic protocol buffer messages (Position, User, Data, etc.) are available from this package.
