 From v0.33b, due to multi ZFS pool support, gocage is no longer 100% compatible with iocage.  
 Zfs datasets now should be specified with the ZFS pool. e.g. :  
-<code>
-Config.Jail_zfs = 1
+<pre><code>Config.Jail_zfs = 1
 Config.Jail_zfs_dataset = myzfspool/poudriere
 Config.Jail_zfs_mountpoint = none

+Create jails
+------------
+You need to specify release, and optional configuration:  
+<pre><code>gocage create jail1 -r 13.2-RELEASE -p "Config.Ip4_addr='vnet0|192.168.1.91/24',Config.Ip6=none,Config.Boot=1"
+</code></pre>
+
+Create basejail. A basejail is a jail based on a release: system will be nullfs read-only mounted from the release directory. Main advantage is that release updates will immediately apply to jails based on this release. Another advantage is that jail system is mounted read-only, a plus from a security perspective:  
+<pre><code>gocage create -b -r 14.0-RELEASE basejail1
+</code></pre>
+

 List jails
 ----------
-Nothing fancy, just use  
-`gocage list`
+<pre><code>gocage list</code></pre>

 ### Specify fields to display

 Use -o to specify which fields you want to display:  
-<pre><code>

+<pre><code>gocage list -o JID,Name,Running,Config.Boot,Config.Comment

 Just add name on gocage list command :

 ### By field value
 You can filter jails with -f option, followed by key=value. Suppose you want to see only active at boot jails:  
-<pre><code>

 Sort jails  
 ----------
 Use -s switch followed by sort criteria. Criteria is a field name, prefixed with + or - for sort order (increase/decrease):  
-<pre><code>
-gocage list -f Config.Boot=1,Running=true -o JID,Name,Running,Config.Boot -s +JID
+<pre><code>gocage list -f Config.Boot=1,Running=true -o JID,Name,Running,Config.Boot -s +JID

 You can use up to 3 criteria, delimited with comma.  
 As an example, you want to list boot priorities of automatically starting jails:  
-<pre><code>

 Stop jails  
 ----------
-`gocage stop test`
-
+<pre><code>gocage stop test</code></pre>

 Update jails  
 ----------
 To update jail patch version, use gocage update :  
-`gocage update test`
+<pre><code>gocage update test</code></pre>

+Update basejails/releases  
+----------
+To update basejails, you need to update the release they are based on. Specify release with -r, and the datastore storing concerned release with -d :  
+<pre><code>gocage update -d fastgocage -r 14.1-RELEASE</code></pre>
+
+Upgrade jails  
+----------
+To upgrade jail to newer release, use gocage upgrade :  
+<pre><code>gocage upgrade -r 13.2-RELEASE test</code></pre>
+  
+A pre-upgrade snapshot wil be made so you can rollback if needed.  
+
+Upgrading basejail/release
+----------
+Upgrading basejails currently needs to be done manually, for each jail.  
+The idea is to stop the jail, change the content of its fstab file to point to the new release, then start jail.  
+If one change the fstab while the jail is running, its system directories won't be unmounted at stop time and this will provoke stop errors.  
+To minimize downtime, the change could be scripted:  
+<pre><code>gocage stop jail1
+sed -i .bak 's/14.0-RELEASE/14.1-RELEASE/' /iocage/jails/jail1/fstab
+# Avoid race-condition by waiting for the update in fstab
+until grep -q 14.1-RELEASE /iocage/jails/jail1/fstab; do sleep 0.2; done
+gocage start jail1
+</code></pre>
+
+You can now update ports.

 Delete jails  
 ----------
-`gocage destroy test`
+<pre><code>gocage destroy test</code></pre>


 Multi datastore  
 ----------
 A datastore is a ZFS dataset mounted. It should be declared in gocage.conf.yml, specifying its ZFS mountpoint :
-<pre><code>
-datastore:
+<pre><code>datastore:
  - /iocage
  - /fastiocage
-</pre></code>
+</code></pre>

 In gocage commands, datastore name is the mountpoint without its "/" prefix.

 Migrating jails  
 ----------
@ -197,27 +221,23 @@ Be aware the moment you migrate a jail to another datastore than /iocage default
 Then you need to disable iocage service, and enable gocage so the jails will start automatically at boot.  
 Also make sure, if you don't destroy source jail, that it won't have the "boot" property set or you will have the 2 jails up at boot.

 Fetch  
 ----------
 Files can be fetched from custom repository, or from local directory with "from" option.  
 For example if you destroyed releases/12.3-RELEASE and still have the downloaded files in /iocage/download/12.3-RELEASE:  
-<pre><code>
-gocage fetch -r 12.3 -o iocage --from file:/iocage/download
