+docker build -t cosmwasm/faucet:manual --file faucet.Dockerfile .
+```
+
+- Version and help
+
+```sh
+docker run --read-only --rm cosmwasm/faucet:manual version
+docker run --read-only --rm cosmwasm/faucet:manual help
+```
+
+- Run faucet locally
+
+```sh
+DOCKER_HOST_IP=$(docker run --read-only --rm alpine ip route | awk 'NR==1 {print $3}') \
+  FAUCET_CONCURRENCY=3 FAUCET_MNEMONIC="economy stock theory fatal elder harbor betray wasp final emotion task crumble siren bottom lizard educate guess current outdoor pair theory focus wife stone" \
