+# Some useful commands to know to manage your instance
+You need to run them from you pixelfed folder (usually `/var/www/pixelfed`).
+
+## Applying changes from the `.env` config file
+
+Once you made some changes, you need to run `php8.2 artisan config:cache && php8.2 artisan cache:clear` to apply them.
+Note: this will disconnect any logged-in account (including from the admin web UI).
+
+## Removing avatar cache to save space
+`php8.2 artisan avatar:storage-deep-clean`
+
+Use it to prune old avatars that are outdated or no longer used. This might save some disk space.
+
+## Fix missing avatars or refetch them.
+`php8.2 artisan  avatar:storage`
+
+It can be used to fetch remote avatars that are not loaded (or in case you deleted `/var/www/pixelfed/storage/app/public/cache/avatars` where they are stored).
+It might also be usefull to migrate that cache (only, not the other existing media) to an S3 storage, by refectching all of them.
+
+Be aware that this will generate a lot of "jobs" that will take time to be completed, and have a significant load on your server (especially bandwith and CPU).
+
+## When using S3
+
+- Delete non-used media that where not cleaned (it happens) : `php8.2 artisanmedia:gc` (Delete media uploads not attached to any active statuses)
+
+- Same but for media stored on S3 storage and still locally stored (doubles) : `php8.2 artisan media:s3gc` (Delete (local) media uploads that exist on S3)
+
+- Migrate your media to an S3 storage (you need to configure it first), so media uploaded before configuring S3 are migrated there: `php8.2 artisanmedia:migrate2cloud` (Move older media to cloud storage)
+
+- Migrate from one S3 backend the other one (change the configuration first): `php8.2 artisanmedia:cloud-url-rewrite` (Rewrite S3 media urls from local users)
