# APPEND

## Synopsis

**`APPEND key string_value`**

This command appends a value to the end of the string that is associated with the given `key`.

- If the `key` already exists, the given `string_value` is appended to the end of the string value that is associated with the `key`.
- If the `key` does not exist, it is created and associated with an empty string.
- If the `key` is associated with a non-string value, an error is raised.

## Return value
