\n\nSee our [documentation page](https://oraios.github.io/serena/02-usage/025_jetbrains_plugin.html) for further details and instructions on how to apply the plugin.\n\n## Features\n\nSerena provides a wide range of tools for efficient code retrieval, editing and refactoring, as well as \na memory system for long-lived agent workflows.\n\nGiven its large scope, Serena adapts to your needs by offering a multi-layered configuration system.\n\n
