 ## Build
 
+If you want to bypass the Makefile:
+
+```bash
+export CGO_CFLAGS="-I$GOPATH/src/github.com/harmony-one/bls/include -I$GOPATH/src/github.com/harmony-one/mcl/include -I/usr/local/opt/openssl/include"
+export CGO_LDFLAGS="-L$GOPATH/src/github.com/harmony-one/bls/lib -L/usr/local/opt/openssl/lib"
+export LD_LIBRARY_PATH=$GOPATH/src/github.com/harmony-one/bls/lib:$GOPATH/src/github.com/harmony-one/mcl/lib:/usr/local/opt/openssl/lib
+export LIBRARY_PATH=$LD_LIBRARY_PATH
+export DYLD_FALLBACK_LIBRARY_PATH=$LD_LIBRARY_PATH
+export GO111MODULE=on
+```
 Note : Some of our scripts require bash 4.x support, please [install bash 4.x](http://tldrdevnotes.com/bash-upgrade-3-4-macos) on MacOS X.
-Make sure you set `export GO111MODULE=on`.
 
 ### Build all executables
 
-You can  run the script `./scripts/go_executable_build.sh` to build all the executables.
