NixOS is installed on server

Connect by ssh

Add the channel hydra.aria.life and binary cache

 $ nix-channel --add https://hydra.aira.life/project/aira/channel/latest
 $ nix-channel --update

Edit configuration.nix

     };

Update with new configurationО
```
 $ nixos-rebuild switch
```
Install parity, ipfs
```
 $ nix-env -i parity-1.8.2 ipfs
```
Mount /storage from RaspberryPi locally. Use the address from cjdns configuration step
```
 $ sshfs pi@[<IPv6>]:/storage storage/
```
Create new parity account
```
 $ parity --chain ropsten account new
```
Save the password
```
 $ echo “*********” > pass
```
Send ETH to the account from step 7
Send ETH to 0xC00Fd9820Cd2898cC4C054B7bF142De637ad129A smart-contract. It will send WETH back to you according your ETH value. Also you need to get utility token (0x5df531240f97049ee8d28a8e51030a3b5a8e8ce4). You can ask for it Airalab's engineers.

Launch Parity

$ parity --chain ropsten --unlock <account> --password pass

Launch IPFS

$ ipfs daemon --enable-pubsub-experiment
$ ipfs pubsub sub aira_market

Launch robonomics_market

$ source .nix-profile/setup.bash
$ roslaunch robonomics_market market.launch

Launch robonomics_liability

$ roslaunch robonomics_liability liability.launch

You are needed a script to publish the data to IPFS (https://goo.gl/LWuN3X)
```
$ ./publishnode.py
```
