 $ cat ./node/skywire.json|grep static_public_key |cut -d ':' -f2 |tr -d '"'','' '

 In case you need more dockerized nodes or maybe it's needed to customize node
 let's look how to create new node.
 
 ```bash
 # 1. We need a folder for docker volume
 $ mkdir /tmp/SKYNODE
-# 2. compile  `skywire-node` 
+# 2. compile  `skywire-node`
 $ GO111MODULE=on GOOS=linux go build -o /tmp/SKYNODE/skywire-node ./cmd/skywire-node
 # 3. compile apps
 $ GO111MODULE=on GOOS=linux go build -o /tmp/SKYNODE/apps/chat.v1.0 ./cmd/apps/chat
