+Lithe requires macOS 14 or later. Java project features require a JDK; JDK 17 or JDK 21 is recommended. Maven projects need either a project `mvnw` or a system Maven installation. Lightweight completion does not start an external process; when a matching language server is installed, Lithe routes the capabilities it actually advertises through the shared Rust LSP Core. See the [language tooling and LSP architecture](./docs/architecture/language-tooling.md) for provider configuration and compatibility details.
