-    - allowed patterns. This is equivalent to coc.nvim's "rootPatterns"
+    - |lspconfig.util.root_pattern(pattern1, pattern2...)| is a variadic function which
+      takes string patterns as arguments, and finds an ancestor 
+      which contains one of the files matching the pattern. 
+      Each pattern can be a specific filename, such as ".git", or a glob.
