+## Dockerized
+
+We provide a docker image to help with test setups. There are two modes to use it
+
+Build:  `docker build  -t wasmd:manual .`  or pull from dockerhub
+
+### Dev server
+
+Bring up a local node with a test account containing tokens
+
+This is just designed for local testing/CI - DO NOT USE IN PRODUCTION
+
+```sh
+docker volume rm -f wasmd_data
+
+# pass password (one time) as env variable for setup, so we don't need to keep typing it
+# add some addresses that you have private keys for (locally) to give them genesis funds
+docker run --rm -it \
+    -e PASSWORD=my-secret-password \
+    --mount type=volume,source=wasmd_data,target=/root \
+    wasmd:manual ./setup.sh cosmos1pkptre7fdkl6gfrzlesjjvhxhlc3r4gmmk8rs6
+
+# This will start both wasmd and wasmcli rest-server, only wasmcli output is shown on the screen
+docker run --rm -it -p 26657:26657 -p 26656:26656 -p 1317:1317 \
+    --mount type=volume,source=wasmd_data,target=/root \
+    wasmd:manual ./run_all.sh
+
+# view wasmd logs in another shell
+docker run --rm -it \
+    --mount type=volume,source=wasmd_data,target=/root,readonly \
+    wasmd:manual ./logs.sh
+```
+
+### CI
+
+For CI, we want to generate a template one time and save to disk/repo. Then we can start a chain copying the initial state, but not modifying it. This lets us get the same, fresh start every time.
+
+```sh
+# Init chain and pass addresses so they are non-empty accounts
+rm -rf ./template && mkdir ./template
+docker run --rm -it \
+    -e PASSWORD=my-secret-password \
+    --mount type=bind,source=$(pwd)/template,target=/root \
+    wasmd:manual ./setup.sh cosmos1pkptre7fdkl6gfrzlesjjvhxhlc3r4gmmk8rs6
+
+sudo chown -R $(id -u):$(id -g) ./template
+
+# FIRST TIME
+# bind to non-/root and pass an argument to run.sh to copy the template into /root
+# we need wasmd_data volume mount not just for restart, but also to view logs
+docker volume rm -f wasmd_data
+docker run --rm -it -p 26657:26657 -p 26656:26656 -p 1317:1317 \
+    --mount type=bind,source=$(pwd)/template,target=/template \
+    --mount type=volume,source=wasmd_data,target=/root \
+    wasmd:manual ./run_all.sh /template
+
+# RESTART CHAIN with existing state
+docker run --rm -it -p 26657:26657 -p 26656:26656 -p 1317:1317 \
+    --mount type=volume,source=wasmd_data,target=/root \
+    wasmd:manual ./run_all.sh
+
+# view wasmd logs in another shell
+docker run --rm -it \
+    --mount type=volume,source=wasmd_data,target=/root,readonly \
+    wasmd:manual ./logs.sh
+```
