+# LGND Expire Sticky Posts
+This plugin automatically expires sticky posts after a set number of days (by default, 14). To use:
+
+- Edit the `lgnd-expire-stickies.php` file to set the appropriate value of `LGND_EXPIRE_STICKIES_DAYS`
+- Install the plugin by uploading it to the Plugins page in your WordPress backend
+- Activate the plugin
+
+Once installed and activated, the plugin will run using wp-cron **hourly**, selecting all sticky posts older than `LGND_EXPIRE_STICKIES_DAYS` and unstickying them.
