-## Configuration
-
-### default
-
-Tidy comes with the below default configuration:
+or with lazy-loading
 
 ```lua
-local M = {
-    config = {
-        eof_quant = -1,  -- the amount of empty lines to leave at the end of
-                         -- the file; -1 = no lines, 0 = 1 line, no limit;
-                         -- only applies if "eof" given to "fmts"
-
-        fmts = {         -- the types of formattings to apply
-            "eof",       -- removes lines at end of file
-            "multi",     -- condenses multiple newlines into one
-            "sof",       -- removes lines at start of file
-            "ws"         -- removes trailing whitespace
-        }
-    }
-}
+use{ "McAuleyPenney/tidy.nvim", event = "BufWritePre" }
 ```
 
-### how to customize
-
-To customize which formattings will apply, give a list to the `setup` function:
-
-```lua
-use{
-    "mcauley-penney/tidy.nvim",
-    config = function()
-        require "tidy".setup{
-            fmts = {
-                "eof",
-                "ws"
-            }
-       }
-   end,
-   event  = "BufWritePre"
-}
-```
