 # goBlockchainDataAnalysis
 blockchain data analysis, written in Go
 
+### Install
+1. Nodejs & NPM https://nodejs.org/
+2. MongoDB https://www.mongodb.com/
+3. Faircoin wallet https://download.faircoin.world/
+4. goBlockchainDataAnalysis https://github.com/arnaucode/goBlockchainDataAnalysis
 
+### Configure
+- Wallet /home/user/.faircoin2/faircoin.conf:
+```
+rpcuser=usernamerpc
+rpcpassword=password
+rpcport=3021
+rpcworkqueue=2000
+server=1
+rpcbind=127.0.0.1
+rpcallowip=127.0.0.1
+```
+
+- goBlockchainDataAnalysis/config.json:
+```json
+{
+    "user": "usernamerpc",
+    "pass": "password",
+    "host": "127.0.0.1",
+    "port": "3021",
+    "genesisTx": "7c27ade2c28e67ed3077f8f77b8ea6d36d4f5eba04c099be3c9faa9a4a04c046",

+}
+```
+
+### Run
 
-## Run
+1. Start MongoDB
+```
+sudo service mongod start
+```
+
+2. Start wallet
+```
+./faircoind -txindex -reindex-chainstate
+```
 
-- First run explorer
+3. Run explorer, to fill the database
 ```
 ./goBlockchainDataAnalysis -explore
 ```
+
+    3.1. The next runs, once the database have data, can just run:
+```
+./goBlockchainDataAnalysis
+```
+
+4. Run the webserver, in the /web directory
+```
+npm start
+```
+Webapp will run on 127.0.0.1:8080
+
