+# Autosave package
+
+Autosaves editor when they lose focus, are destroyed, or when the window is closed.
+
+This package is disabled by default and can be enabled via the `autosave.enabled` config
+setting or by checking *Enabled* in the settings for the *autosave* package in the
+Settings view.
+
+## Service API
+The service exposes an object with a function `dontSaveIf`, which accepts a callback.
+Callbacks will be invoked with each pane item eligible for an autosave and if the callback
+returns true, the item will be skipped.
+
+### Usage
