+    summary: A Moodle plugin for powerline-go
+    description: |
+      This plugin adds a segment to powerline-go which displays the [Moodle](https://moodle.org) version the current directory belongs to.
+
+      Once installed, add `moodle` to the `-modules` argument when you configure `powerline-go` for your shell.
+      For example, for Bash, your `.bashrc` should contain something like:
+
+      ```bash
+      function _update_ps1() {
+        PS1="$($HOME/go/bin/powerline-go \
+        -error $? \
+        -jobs $(jobs -p | wc -l) \
+        -hostname-only-if-ssh \
+        -modules 'aws,cwd,git,root,exit,moodle')"
+      }
