+# 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)
