+#### Language Server Settings
+
+Language servers can be configured with different mechanisms, all merged together to form the *effective* settings for a language server instance.
+There are three kinds of settings:
+
+1. *Global settings* specified by the user in its `vis` configuration in a language server configuration's `settings` member.
+2. *Project local* settings stored in a `.vis-lspc-settings.json` file along your regular project files.
+3. Settings stored by `vis-lspc` in the `settings.json` file.
+   The *client local* user settings are stored for each language server and each file path.
+   Settings for a more specific file path override settings defined for a parent directory.
+
+The *project* and *client local* settings are indexed by the name of the language server.
+
+All relevant settings are merged to form the *effective* settings passed to the language server.
+More specific settings take precedence before more general ones.
+
 ### Workspace Detection
 
 During server initialization an URI to the root of the workspace (a folder opened by the editor) can be passed to the server.
