-# Overview
+# pb3-gen-sol 
 
-pb3-gen-sol is a proto3 to solidity library generator that supports proto3 native types and uses field option for solidity native types. Both the message and generated code are more efficient than other solutions. It also includes a library to decode protobuf wireformat. Currently it generates decoders, with encoder support planned.

 ## Usage
 ### .proto files
 Example:
 ```protobuf
 syntax = "proto3";
-// package name is used for both generated .sol file name and library name
+// package name is used for both generated .sol file name and library
+name
 package mytest;
 
 import "google/protobuf/descriptor.proto";
 extend google.protobuf.FieldOptions {
-    string soltype = 54321;  // must > 1001 and not conflict with other extensions
+    string soltype = 54321;  // must > 1001 and not conflict with other
+extensions
 }
 
 message MyMsg {
     bytes addr = 1 [ (soltype) = "address" ];
     uint32 num = 2 [ (soltype) = "uint8" ];
-    bool has_moon = 3;  // for matching native types, no need for soltype option
+    bool has_moon = 3;  // for matching native types, no need for
+soltype option
 }
 ```

-proto files can have different package names, and generated .sol file name is proto package name.
+proto files can have different package names, and generated .sol file
+name is proto package name.
 
 ## Params
-- `msg`: only generate solidity struct and decode functions for msg name. Multiple can be specified.
-- `importpb`: default false, if set to true, generated .sol file will import pb.sol instead of embed library pb in the file

 Example:
 
-```$ protoc --sol_out=msg=Msg1,msg=Msg2,msg=Msg3,importpb=true:test/solidity/contracts/lib/ test/test.proto```

-## Kwown Issues
-- No support for int32/int64
-- Support embedded message/enum, but no nested message/enum definition
+```$ protoc
+--sol_out=msg=Msg1,msg=Msg2,msg=Msg3,importpb=true:test/solidity/contracts/lib/
+test/test.proto
+```
