 # Federated Wiki Farm
 
-Start Playing Federated Wiki: http://start.fed.wiki
+http://fed.wiki.org
 
-### Run a local wiki farm
+### Get acquainted with wiki.
 
-    docker run -p 3000:3000 -it --rm \
-      dobbs/farm
+Launch the container:
+``` bash
+docker run -p 3000:3000 -it --rm \
+  dobbs/farm
+```
 
-Visit http://localhost:3000 and http://anything.localtest.me:3000
+Visit http://localhost:3000
 
-### Run a local wiki that will survive a reboot
+### Make your wiki survive a reboot
 
-    docker run -p 3000:3000 -it --rm \
-      -v ~/.wiki:/home/node/.wiki \
-      dobbs/farm
+Create a volume:
 
-Your wiki pages and configuration will be saved in the ~/.wiki folder.
+``` bash
+docker volume create dot-wiki
+```
 
-# Release Notes for 1.0.0
+Launch the container:
+``` bash
+docker run -p 3000:3000 -it --rm \
+  -v dot-wiki:/home/app/.wiki \
+  dobbs/farm
+```
 
-This is a significant **breaking** change from pre-1.0 releases. Especially:
+Visit http://localhost:3000
 
-* 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)`)
+### Make your wiki a local farm
 
-* no longer installing `bash`, `configure-wiki`, nor `set-owner-name`
+We're going to use http://localtest.me instead of localhost for our
+domain name.  See http://readme.localtest.me for more info.
 
-* no longer creating `/home/app/.wiki/wiki.json`
+Let's also use a different volume for this one:
+``` bash
+docker volume create localtest.me
+```
 
-Those changes in particular will impose some work on authors upgrading
-from previous versions.
+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
+```
 
-The last non-breaking revision is 0.52.0 https://github.com/dobbs/farm/tree/0.52.0#readme
+Open http://this.localtest.me:3000 in one tab.
+Open http://that.localtest.me:3000 in another.
