```

as `zcash-explorer` user

```
cd 
git clone https://github.com/nighthawk-apps/zcash-explorer.git
cd zcash-explorer
## Create .env ( check ENV varsiable doc )
source .env
mix deps.get
cd assets/
npm i
npm run deploy
cd ..
MIX_ENV=prod mix phx.digest

```
    location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_http_version 1.1;
    proxy_set_header Origin '';
    proxy_redirect off;
    proxy_pass http://localhost:4000;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
  }
```
