 ========
-A tool to decompile [protoc](https://github.com/protocolbuffers/protobuf) compiled protobuf classes back into .proto definitions.
+A tool to decompile protobuf classes compiled by [protoc](https://github.com/protocolbuffers/protobuf), from CIL assemblies back into .proto definitions.
 
 Usage
 -----
 ```
-Usage: [command] [arguments...] [options...] [-h|--help] [--version]                                                                                                                                                                                                                    
+Usage: protodec(.exe) <target_assembly_path> <out_path> [options]
-Use reflection backend to load target CIL assembly and its dependants.
-
 Arguments:
-  [0] <string>    Either the path to the target assembly or a directory of assemblies, all of which be parsed.
+  target_assembly_path  Either the path to the target assembly or a directory of assemblies, all of which be parsed.
-  [1] <string>    An existing directory to output into individual files, otherwise output to a single file.
+  out_path              An existing directory to output into individual files, otherwise output to a single file.
-
 Options:
-  --skip-enums                                                  Skip parsing enums and replace references to them with int32. (Optional)
+  --debug                                                     Drops the minimum log level to Debug.
-  --include-properties-without-non-user-code-attribute          Includes properties that aren't decorated with `DebuggerNonUserCode` when parsing. (Optional)
+  --parse_service_servers                                     Parses gRPC service definitions from server classes.
-  --include-service-methods-without-generated-code-attribute    Includes methods that aren't decorated with `GeneratedCode("grpc_csharp_plugin")` when parsing gRPC services. (Optional)
+  --parse_service_clients                                     Parses gRPC service definitions from client classes.
-  --parse-service-servers                                       Parses gRPC service definitions from server classes. (Optional)
+  --skip_enums                                                Skip parsing enums and replace references to them with int32.
-  --parse-service-clients                                       Parses gRPC service definitions from client classes. (Optional)
+  --include_properties_without_non_user_code_attribute        Includes properties that aren't decorated with `DebuggerNonUserCode` when parsing.
-  --log-level <LogLevel>                                        Logging severity level. (Default: Information)
+  --include_service_methods_without_generated_code_attribute  Includes methods that aren't decorated with `GeneratedCode("grpc_csharp_plugin")` when parsing gRPC services.
-
-Commands:
-  il2cpp    Use LibCpp2IL backend to directly load Il2Cpp compiled game assembly. EXPERIMENTAL.
 ```
-See per-command help message for more info.
 
 Limitations
 -----------
 - Integers are assumed to be (u)int32/64 as CIL doesn't differentiate between them and sint32/64 and (s)fixed32/64.
 - Package names are not preserved in protobuf compilation so naturally we cannot recover them during decompilation, which may result in naming conflicts.
-- When decompiling from [Il2CppDumper](https://github.com/Perfare/Il2CppDumper) DummyDLLs or from an Il2Cpp assembly older than metadata version 29, due to the development branch of [LibCpp2Il](https://github.com/SamboyCoding/Cpp2IL/tree/development/LibCpp2IL) not yet recovering method bodies
+- When decompiling from [Il2CppDumper](https://github.com/Perfare/Il2CppDumper) DummyDLLs
-    - The `Name` parameter of `OriginalNameAttribute` is not parsed. In this case, the CIL enum field names are used after conforming them to protobuf conventions.
+    - The `Name` parameter of `OriginalNameAttribute` is not dumped. In this case, the CIL enum field names are used after conforming them to protobuf conventions
-    - The `Tool` parameter of `GeneratedCodeAttribute` is not compared against when parsing gRPC service methods, which may cause false positives in the event that another tool has generated methods in the service class.
