+    <p>
+      You might have a plugin that's failing. If you installed any
+      custom plugins manually, they may not function correctly with
+      this version of DokuWiki. You should look in they
+      Grain Log for this grain to examine the errors from PHP-FPM.
+      If the issue is in plugin code, you'll have to remove the plugin manually
+      from the grain's filestructure via backup and restore.
+      You can then try installing a new version of the plugin, or find
+      a different one with better compatibility.
+    </p>
+
+    <h2>To fix a plugin issue:</h2>
+
+    <ol>
+      <li>Download a Backup of the grain.</li>
+      <li>Unzip the grain archive.</li>
+      <li>
+        Find the plugin that the error is referring to in
+        the <code>data/lib/dokiwiki/lib/plugins</code> folder and remove the
+        plugin's folder.
+      </li>
+      <li>
+        Zip up the unzipped grain archive, taking care to
+        preserve the same root files/folders as the original
+        Zip file.
+      </li>
+      <li>
+        Restore the grain from backup using the new Zip file.
+      </li>
+      <li>
+        Run the new grain. If it's working again, great!
+        If not, see if the error is still with plugins that
+        need removal/upgrading.

+# DokuWiki Sandstorm
+
+Run [DokuWiki](https://www.dokuwiki.org/dokuwiki) on [Sandstorm](https://sandstorm.io/).
+A lightweight wiki for your personal use.
+
+## Details
+
+* Runs in PHP 7 using PHP-FPM and an Nginx reverse proxy
+* Uses Sandstorm authentication
+
+## Troubleshooting
+
+### PHP errors in the page
+
+* See if the script referenced in the error is in `plugins`. You may have a
+  plugin that needs to be upgraded or disabled.
+  * If you can't disable/remove the plugin via the UI:
+    1. Download a backup of the grain
+    2. Unzip the backup into a new folder
+    3. Remove the plugin folder from the unzipped backup tree
+    4. Rezip up the backup tree, preserving the same base folders
+    5. Restore the grain from backup
+
+## Building a new version
+
+### Requirements
+
+* git
+* VirtualBox
+* Vagrant
+* [vagrant-spk](https://docs.sandstorm.io/en/latest/vagrant-spk/installation/)
