----
-title: LSP servers
----
-
-opencode integrates with _Language Server Protocol_, or LSP to improve how the LLM interacts with your codebase.
-
-LSP servers for different languages give the LLM:
-
-- **Diagnostics**: These include things like errors and lint warnings. So the LLM can generate code that has fewer mistakes without having to run the code.
-- **Quick actions**: The LSP can allow the LLM to better navigate the codebase through features like _go-to-definition_ and _find references_.
-
-## Auto-detection
-
-By default, opencode will **automatically detect** the languages used in your project and add the right LSP servers.
-
-## Manual configuration
-
-You can also manually configure LSP servers by adding them under the `lsp` section in your opencode config.
