-# hubble-server
-API server for hubble scan block explorer
+# Hubble Scan Server
+
+*Hubble Scan Server that checks blocks of [Gallactic Blockchain](https://github.com/gallactic/gallactic) and saves them in Postgre database.
+
+## Compiling the code
+
+You need to make sure you have install [Go](https://golang.org/) (version 1.10.1 or higher) and [postgre](https://www.postgresql.org). After installing them, import HubbleScan.sql from script folder into postgre to create database and then you can follow these steps to compile and build the project:
+
+```bash
+mkdir -p $GOPATH/src/github.com/gallactic/hubbleServer
+cd $GOPATH/src/github.com/gallactic/hubbleServer
+git clone https://github.com/gallactic/HUBBLE_SERVER.git .
+make
+```
