+- **CPU:** 1 core
+- **RAM:** 2GB
+- **Storage:** 25GB SSD

+
+# A) Setup
+
+## 1) Install Golang (go)
+
+1.1) Remove any existing installation of `go`
+
+```
+sudo rm -rf /usr/local/go
+```
+
+1.2) Install latest/required Go version (installing `go1.17.2`)
+
+```
+curl https://golang.org/dl/go1.17.2.linux-amd64.tar.gz
+sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz
+```
+
+1.3) Update env variables to include `go`
+
+```
+cat <<'EOF' >>$HOME/.profile
+export GOROOT=/usr/local/go
+export GOPATH=$HOME/go
+export GO111MODULE=on
+export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
+EOF
+
+source $HOME/.profile
+```
+
+1.4) Check the version of go installed
+
+```
+go version
+```
+
+### 2) Install required software packages
+
+```
+sudo apt-get install git curl build-essential make jq -y
+```
+
+### 3) Install `ethermint`
+
+```
+git clone https://github.com/vulcanize/ethermint.git
+cd ethermint
+git fetch --all
+git checkout v0.1.0-dev
+make install
+```
+
+### 4) Verify your installation
+
+```
+ethermintd version --long
+```
+
+On running the above command, you should see a similar response like this. Make sure that the *version* and *commit
+hash* are accurate
+
+```
+name: ethermint
+server_name: ethermintd
+```
+
+### 5) Initialize Node
+
+**Not required if you have already initialized before**
+
+```
+ethermintd init <your-node-moniker> --chain-id ethermint_81337-1
+```
+
+On running the above command, node will be initialized with default configuration. (config files will be saved in node's
+default home directory (~/.ethermintd/config)
+
+NOTE: Backup node and validator keys . You will need to use these keys at a later point in time.
+
+---
+
+# B) Starting Node
+
+## 1) Download Final Genesis
+
+Use `curl` to download the genesis file
+**Replace your **genesis** file with published genesis file**
+
+```shell
+curl http://167.172.173.94:26657/genesis | jq .result.genesis > ~/.ethermintd/config/genesis.json
+```
+
+Verify sha256 hash of genesis file with the below command
+
+```
+jq -S -c -M '' ~/.ethermintd/config/genesis.json | shasum -a 256
+```
+
+genesis sha256 hash should be
+
+```
+4e5b68b5652a608c44c33e669c84ac179d9c0e301f958b5448f037a53c5cbb4e
+```
+
+## 2) Update Peers & Seeds in config.toml
+
+```
+peers="5ad2e6c35f2c84ff3ee31d89a95b34d92cb6afb1@157.230.101.237:26656,defc95b08547b6ef254723ad9621967a7e819020@161.35.223.44:26656"
+sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.ethermintd/config/config.toml
+```
+
+## 3) Start the Full Node
+
+#### 3.1) Start node as `systemctl` service
+
+3.1.1) Create the service file
+
+```
+sudo tee /etc/systemd/system/ethermintd.service > /dev/null <<EOF
+[Unit]
+Description=EthermintD Daemon 
+After=network-online.target
+
+[Service]
+User=$USER 
+ExecStart=$(which ethermintd) start --gql-playground --gql-server 
+Restart=always 
+RestartSec=3
+LimitNOFILE=65535
+
+[Install]
+WantedBy=multi-user.target 
+EOF
+
+```
+
+3.1.2) Load service and start
+
+```
+sudo systemctl daemon-reload 
+sudo systemctl enable ethermintd 
+sudo systemctl start ethermintd
+
+```
+
+3.1.3) Check status of service
+```
+
+sudo systemctl status ethermintd
+
+```
+
+`NOTE:`
+A helpful command here is `journalctl` that can be used to:
+
+  a) check logs
+  ```
+
+journalctl -u ethermintd
+
+  ```
+
+  b) most recent logs
+  ```
+
+journalctl -xeu ethermintd
+
+  ```
+
+  c) logs from previous day
+  ```
+
+journalctl --since "1 day ago" -u ethermintd
+
+  ```
+
+  d) Check logs with follow flag
+  ```
+
+journalctl -f -u ethermintd
+
+  ```

+export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
+EOF
+
+source $HOME/.profile
+```
+
+1.4) Check the version of go installed
+
+```
+go version
+```
+
+### 2) Install required software packages
+
+```
+sudo apt-get update && sudo apt-get install git curl build-essential make jq -y
+```
+
+### 3) Install `ethermint`
+
+```
+git clone https://github.com/vulcanize/ethermint.git
+cd ethermint
+git fetch --all
+git checkout v0.1.0-dev
+make install
+```
+
+### 4) Verify your installation
+
+```
+ethermintd version --long
+```
+
+On running the above command, you should see a similar response like this. Make sure that the *version* and *commit
+hash* are accurate
+
+```
+name: ethermint
+server_name: ethermintd
+```
+
+### 5) Initialize Node
+
+**Not required if you have already initialized before**
+
+```
+ethermintd init <your-node-moniker> --chain-id ethermint_81337-1
+```
+
+On running the above command, node will be initialized with default configuration. (config files will be saved in node's
+default home directory (~/.ethermintd/config)
+
+NOTE: Backup node and validator keys. You will need to use these keys at a later point in time.
+
+---
+
+## 6) Create Account keys
+
+if you have participated in previous testnet and have mnemonic phrase, use below command to recover your account
+
+```
+ethermintd keys add <key-name> --recover
+```
+
+to create new account
+
+```
+ethermintd keys add <key-name>
+```
+
+NOTE: Save `mnemonic` and related account details (public key). You will need to use the need mnemonic/private key to
+recover accounts at a later point in time.
+
+## 7) Add Genesis Account
+
+```
+ethermintd add-genesis-account <key-name> 4500000000000000agnt --keyring-backend os
+```
+
+## 8) Create Your `gentx`
+
+```
+ethermintd gentx <key-name> 4500000000000000agnt \
+  --pubkey=$(ethermintd tendermint show-validator) \
+  --chain-id="ethermint_81337-1" \
+  --moniker="my-moniker" \
+  --website="https://yourweb.site" \
+  --details="description of my validator" \
+  --commission-rate="0.10" \
+  --commission-max-rate="0.20" \
+  --commission-max-change-rate="0.01" \
+  --min-self-delegation="1" 
+```    
+
+Note:
+
+- `<key-name>` and `chain-id` are required. other flags are optional
+- Don't change amount value while creating your gentx
+- Genesis transaction file will be saved in `~/.ethermintd/config/gentx` folder
+
+## 9) Submit Your gentx
+
+Submit your `gentx` file to the [testnets]() in the format of
+`<validator-moniker>-gentx.json`
+
+NOTE: (Do NOT use space in the file name)
+
+To submit the gentx file, follow the below process:
+
+- Fork the [testnets]() repository
+- Upload your gentx file in `ethermint_81337-1/config/gentxs` folder
+- Submit Pull Request to [testnets]() with name `ADD <your-moniker> gentx`
+
+---
+
+**Execute below instructions only after publishing of final genesis file**
+
+genesis file will be published to [testnets/ethermint_9000-1]()
+
+# B) Starting the validator
+
+TBU
+
+## 3) Start the Node
+
+#### 3.1) Start node as `systemctl` service
+
+3.1.1) Create the service file Note: this step is not required if you did setup before
+
+```
+sudo tee /etc/systemd/system/ethermintd.service > /dev/null <<EOF
+[Unit]
+Description=ethermintd Daemon
+After=network-online.target
+
+[Service]
+User=$USER
+ExecStart=$(which ethermintd) start
+Restart=always
+RestartSec=3
+LimitNOFILE=65535
+
+[Install]
+WantedBy=multi-user.target
+EOF
+```
+
+3.1.2) Load service and start
+
+```
+sudo systemctl daemon-reload
+sudo systemctl enable ethermintd
+sudo systemctl start ethermintd
+```
+
+3.1.3) Check status of service
+
+```
+sudo systemctl status ethermintd
+```
+
+`NOTE:`
+A helpful command here is `journalctl` that can be used to:
+
+a) check logs
+
+  ```
+  journalctl -u ethermintd
+  ```
+
+b) most recent logs
+
+  ```
+  journalctl -xeu ethermintd
+  ```
+
+c) logs from previous day
+
+  ```
+  journalctl --since "1 day ago" -u ethermintd
+  ```
+
+d) Check logs with follow flag
+
+  ```
+  journalctl -f -u ethermintd
+  ```

+# Auction Module CLI Commands
+
+## Build the Chain
+
+The following command builds the Ethermint daemon and places the binary in the `build` directory
+
+```
+make build
+
+```
+
+## Setup the Chain
+
+The following steps need to be followed only before running the chain for the first time.
+
+1. Add the root key:
+   ```
+   ./build/ethermintd keys add root
+   ```
+   Keep a note of the keyring passphrase if you set it.
+2. Init the chain:
+   ```
+   ./build/ethermintd init test-moniker --chain-id ethermint_9000-1
+   ```
+3. Add genesis account:
+   ```
+   ./build/ethermintd add-genesis-account $(./build/ethermintd keys show root -a) 1000000000000000000aphoton,1000000000000000000stake
+   ```
+4. Make a genesis tx:
+   ```
+   ./build/ethermintd gentx root 1000000000000000000stake --chain-id ethermint_9000-1 
+   ```
+5. Collect gentxs:
+   ```
+   ./build/ethermintd collect-gentxs
+   ```
+
+The chain can now be started using:
+
+```
+./build/ethermintd start
+```
+
+## Querying the Params
+
+The following command will dislay the default params for the `auction` module:
+
+```
+# ./build/ethermintd q auction params -o json | jq
+
+{
+  "params": {
+    "commits_duration": "0s",
+    "reveals_duration": "0s",
+    "commit_fee": {
+      "denom": "",
+      "amount": "0"
+    },
+    "reveal_fee": {
+      "denom": "",
+      "amount": "0"
+    },
+    "minimum_bid": {
+      "denom": "",
+      "amount": "0"
+    }
+  }
+}
+```
+
+## Auction TX CLI Commands
+
+### Create Auction
+
+```
+# ./build/ethermintd tx auction create 100s 100s 10aphoton 10aphoton 1000aphoton --from root --chain-id $(./build/ethermintd status | jq .NodeInfo.network -r)
