+# @cosmwasm/faucet
+
+The faucet is built as part of the monorepo. In the repo root do:
+
+```
+yarn install
+yarn build
+```
+
+Then start it for a Wasmd development blockchain using:
+
+```
+cd packages/faucet
+yarn dev-start
+```
+
+Advanced users that want to provide their custom config can start as follows:
+
+```
+FAUCET_CREDIT_AMOUNT_COSM=10 \
+  FAUCET_CREDIT_AMOUNT_STAKE=5 \
+  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" \
+  ./bin/cosm-faucet start cosmwasm "http://localhost:1317"
+```
+
+## Usage
+
+```
+sage: cosmwasm-faucet action [arguments...]
+
+Positional arguments per action are listed below. Arguments in parentheses are optional.
+
+help      Shows a help text and exits
+
+version   Prints the version and exits
+
+generate  Generates a random mnemonic, shows derived faucet addresses and exits
+           1  Codec
+           2  Chain ID
+
+start     Starts the faucet
+           1  Codec
+           2  Node base URL, e.g. wss://bov.friendnet-fast.iov.one
+
+Environment variables
+
+FAUCET_CONCURRENCY        Number of distributor accounts. Defaults to 5.
+FAUCET_PORT               Port of the webserver. Defaults to 8000.
+FAUCET_MNEMONIC           Secret mnemonic that serves as the base secret for the
+                          faucet HD accounts
+FAUCET_CREDIT_AMOUNT_TKN  Send this amount of TKN to a user requesting TKN. TKN is
+                          a placeholder for the token ticker. Defaults to 10.
+FAUCET_REFILL_FACTOR      Send factor times credit amount on refilling. Defauls to 8.
+FAUCET_REFILL_THRESHOLD   Refill when balance gets below factor times credit amount.
+                          Defaults to 20.
+```
+
+### Faucet HD wallet
+
+The faucet uses standard HD paths for each blockchain, e.g.
+
+```
+IOV        m/44'/234'/a'
+Lisk       m/44'/134'/a'
+CosmWasm   m/44'/118'/0'/0/a
+```
+
+where `a` is a 0-based index of the account. Account 0 is the token holder and
+account 1...FAUCET_CONCURRENCY are the distributor accounts.
+
+This means the token holder account can be accessed using the Neuma wallet when
+the same mnemonic is used. Accessing the distributor accounts will be possible
+as soon as there is
+[multi account support](https://github.com/iov-one/ponferrada/milestone/3).
+
+### Working with docker
+
+- Build an artifact ()
+
+```sh
+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 $3}') \
+  FAUCET_CONCURRENCY=3 FAUCET_MNEMONIC="economy stock theory fatal elder harbor betray wasp final emotion task crumble siren bottom lizard educate guess current outdoor pair theory focus wife stone" \
+  docker run --read-only --rm \
+  -e FAUCET_MNEMONIC \
+  -e FAUCET_CONCURRENCY \
+  -p 8000:8000 \
+  cosmwasm/faucet:manual \
+  start cosmwasm "http://$DOCKER_HOST_IP:1317"
+```
+
+### Using the faucet
+
+Now that the faucet has been started up, you can send credit requests to it.
+This can be done with a simple http POST request. These commands assume the
+faucet is running locally, be sure to change it from `localhost` if your
+situation is different.
+
+```
+curl --header "Content-Type: application/json" \
+  --request POST \
+  --data '{"ticker":"CASH","address":"tiov1k898u78hgs36uqw68dg7va5nfkgstu5z0fhz3f"}' \
+  http://localhost:8000/credit
+```
+
+### Checking the faucets status
+
+The faucet provides a simple status check in the form of an http GET request. As
+above, make sure to adjust the URL as necessary.
+
+```
+curl http://localhost:8000/status
+```
