+#### `cache` Preset
+
+The `cache` preset does not provide a default import and needs to be imported explicitly.

+
+It provides two different caches:
+
+- `sharedCache`: This cache is shared over all languages and all scripts (file-based and UI). Usage of entries is tracked and entries will be removed if the last script that ever accessed an entry is removed.
+- `privateCache`: This cache is private to a script engine, usually that means it is private to a script or rule, depending on the implementation of the scripting language.
+It is cleared when the script engine is unloaded (i.e. usually when the script is unloaded).
+
+In both cases values that are either a `ScheduledFuture<?>` or a `Timer` are cancelled by calling `.cancel()` on the object if the object is removed automatically.
+
+Both caches implement the `ValueCache` interface and therefore can be accessed by
+
+- `Object put(String key, Object value)`: Put a key/value pair to the cache. Returns old value if already set, otherwise `null`.
+- `Object remove(String key)`: Remove the key/value pair from the cache. Returns old value if already set, otherwise `null`.
+- `Object get(String key)`: Get the value for the given key from the cache. Non-existent keys return `null`.
+- `Object get(String key, Supplier<Object> supplier`: Get the value for the given key. If no value is present, add the value that is return from the `supplier`.

 ### `TriggerType` Objects (all JSR223 languages)
 
 The following trigger types are defined by openHAB (custom triggers can also be defined) and take the specified configuration parameters.
