<title>Description</title>
<para>
Flatpak maintains a list of patterns that define which refs are pinned.
A pinned ref will never be automatically uninstalled (as are unused
runtimes periodically). This can be useful if for example you are using
a runtime for development purposes.
</para>
<para>
Runtimes that are explicitly installed, rather than installed as a
dependency of something else, are automatically pinned.
</para>
<para>
The patterns are just a partial ref, with the * character matching anything
within that part of the ref. Only runtimes can be pinned, not apps. Here
are some example patterns:
<programlisting>
org.some.Runtime
org.some.Runtime//unstable
runtime/org.domain.*
org.some.Runtime/arm
</programlisting>
</para>
<para>
To list the current set of pins, run this command without any patterns.
