+## gRPC 
+
+You can view gRPC calls by constructing the Request and Response from GRPC models:
+
+```swift
+public func addGRPC(url: String,
+                        host: String,
+                        requestObject: Data?,
+                        responseObject: Data?,
+                        success: Bool,
+                        statusCode: Int,
+                        statusMessage: String?,
+                        duration: Double?,
+                        HPACKHeadersRequest: [String: String]?,
+                        HPACKHeadersResponse: [String: String]?)
+```
+Example
+
+```swift
+// Your GRPC services that is generated from SwiftGRPC
+private let client = NoteServiceServiceClient.init(address: "127.0.0.1:12345", secure: false)
+
+
+func insertNote(note: Note, completion: @escaping(Note?, CallResult?) -> Void) {
+    _ = try? client.insert(note, completion: { (createdNote, result) in
+
+        // Add to atlantis and show it on Proxyman app
+        NetShears.shared.addGRPC(url: "https://test.com/grpc",
+                         requestObject: try? note.jsonUTF8Data(),
+                         responseObject: try? createdNote.jsonUTF8Data(),
+                         success: result.success,
+                         statusCode: result.statusCode.rawValue,
+                         statusMessage: result.statusMessage)
+    })
+}
+```
