+### Make your wiki a local farm
+
+We're going to use http://localtest.me instead of localhost for our
+domain name.  See http://readme.localtest.me for more info.
+
+Let's also use a different volume for this one:
+``` bash
+docker volume create localtest.me
+```
+
+Specify the domain name when you launch your wiki
+``` bash
+docker run -p 3000:3000 -it --rm \
+  -v localtest.me:/home/app/.wiki \
+  -e DOMAIN=localtest.me \
+  dobbs/farm
+```
+
+Open http://this.localtest.me:3000 in one tab.
+Open http://that.localtest.me:3000 in another.
 
 # Development
 
-This image's tag does not match the version of the included wiki
-software. Our version indicates the scale of changes in this tiny
-devops pipeline.
-
-Testing new images locally:
+This image's tag matches the version of the included wiki software.
 
 ``` bash
-TAG=1.0.14-prefer-title
-IMAGE=dobbs/farm:$TAG
-docker build --tag $IMAGE .
+git tag -am "" '0.13.0'
+git push --tags
 ```
 
-You might also want to remember the most recent tag:
-
-``` bash
-git tag --list | tail -1
-```
-
-Update WIKI_VERSIONS.txt
-
-``` bash
-docker run --rm $IMAGE wiki --version > WIKI_VERSIONS.txt
-```
-
-# Publish container images
-
-End-to-end recipe to publish a new version. May require judgment in
-the steps before git push and docker push.
-``` bash
-# Emit current version to standard error and next version to standard out.
-# use that to assign the next TAG
-TAG="$(git tag --list | tail -1 | perl -lne 'print STDERR $_;s/(\d+)$/$1+1/e;print $_;')"
-IMAGE=dobbs/farm:$TAG
-docker build --no-cache --tag $IMAGE .
-docker build --tag dobbs/farm:latest .
-docker run --rm $IMAGE wiki --version > WIKI_VERSIONS.txt
-git add .
-git commit -m "update WIKI_VERSIONS.txt for $TAG"
-git tag -am "" "$TAG"
-git push --atomic origin main "$TAG"
-docker push $IMAGE
-docker push dobbs/farm:latest
-```
-
-Sometimes we publish a docker image with no changes to the wiki source
-code. This allows us to pick up non-breaking changes to some of the
-plugins. Using `--no-cache` ensures docker re-runs this line from the
-`Dockerfile` in particular: `npm install -g --prefix . $WIKI_PACKAGE`.
-
-# Experiment with K8S
-
-With the local kubernetes example (see [examples/k8s/README.md](./examples/k8s/README.md)):
-
-``` bash
-k3d image import $IMAGE --cluster wiki
-kubectl patch deployment.apps/wiki-deployment \
-  --type='json' \
-  -p='[{"op": "replace", "path": "/spec/template/spec/containers/0/image", "value":"'$IMAGE'"}]'
-```
+The repos in Dockerhub and GitHub are configured to automatically build new tags.

-# Release Notes for 1.0.0
-
-This is a significant **breaking** change from pre-1.0 releases. Especially:
-
-* changed the user from `app` (`uid=1001(app) gid=1001(app) groups=1001(app)`)
-  to `node` (`uid=1000(node) gid=1000(node) groups=1000(node),1000(node)`)
-
-* no longer installing `bash`, `configure-wiki`, nor `set-owner-name`
-
-* no longer creating `/home/app/.wiki/wiki.json`
-
-Those changes in particular will impose some work on authors upgrading
-from previous versions.
-
-The last non-breaking revision is 0.52.0 https://github.com/dobbs/farm/tree/0.52.0#readme
