+-- - SKELETONCommand
+--
+-- {config} is the same as |vim.lsp.add_filetype_config()|, but with some
+-- additions and changes:
+--
+-- {SKELETON_log_level}
+--   controls the level of logs to show from build processes and other
+--   window/logMessage events. By default it is set to
+--   vim.lsp.protocol.MessageType.Warning instead of
+--   vim.lsp.protocol.MessageType.Log.
+--
+-- {SKELETON_settings}
+--   This is a table, and the keys are case sensitive.
+--   Example: `SKELETON_settings = { }`
+--
+-- {filetype}
+--   Defaults to {"c", "cpp"}
+--
+-- {cmd}
+--   Defaults to {"SKELETON"}
