-Install required packages:
+Use Ubuntu 16.04 LTS.
 
-    brew update && brew install go
-    export GOPATH=~/go
-    go get github.com/yvasiyarov/gorelic
+Compile Monero source (with libraries option):
 
-Download and compile [Monero](https://github.com/monero-project/monero) **v0.10.0**.
+  cmake -DBUILD_SHARED_LIBS=1 .
+  make
 
-Now clone stratum repo and compile it:
+Install Golang and packages:
 
-    git clone https://github.com/sammy007/go-cryptonote-pool.git
-    cmake .
-    make
+    sudo apt-get install golang
+    export GOPATH=~/go
+    go get github.com/yvasiyarov/gorelic
 
-Notice that for share validation stratum requires monero source tree where .a libs already compiled. By default stratum will use <code>../monero</code> directory. You can override this behavior by passing <code>MONERO_DIR</code> env variable:
+Build CGO extensions:
 
-    MONERO_DIR=/path/to/monero cmake .
+    MONERO_DIR=/opt/src/monero cmake .
     make
 
 Build stratum:
