 etcd-cpp-api is a C++ API for [etcd]
 
 ## Requirements
+1. Build Boost Library(http://www.boost.org/doc/libs/1_61_0/more/getting_started/unix-variants.html)
+    * You can use: ./bootstrap.sh --with-libraries=system,thread,locale,random,chrono,regex,filesystem 
+    * The above command will only compile those libraries indicated, thus it takes less time to build boost
+
+2. Build Casablanca:
+    * Instructions on how to build is here: https://github.com/Microsoft/cpprestsdk/wiki
+    * For Linux environment you can omit libboost-all-dev during apt-get install, if you already have boost library installed.
+
+3. Install Protobuf:
+    * https://github.com/google/protobuf/blob/master/src/README.md
+
+4. Install Protoc for C++:
+    * https://github.com/grpc/grpc/blob/release-0_14/INSTALL.md
 
-   * [C++ REST SDK](http://casablanca.codeplex.com/)
-   * Boost libraries
-   * [Catch](https://github.com/philsquared/Catch) for testing 
-   * protobuf (https://github.com/google/protobuf/blob/master/src/README.md)
-   * grpc (https://github.com/grpc/grpc/blob/release-0_14/INSTALL.md)

 ## compiling .proto
 Proto files are stored in /proto. The proto files defined the interface of etcdv3.
 You can compile it like this(if you are running this command inside /proto folder)
-$ protoc -I . --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_cpp_plugin` ./rpc.proto
-$ protoc -I . --cpp_out=. ./*.proto
+*$ protoc -I . --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_cpp_plugin` ./rpc.proto
