Updates logic for running file in normal mode and adds a variable for remapping the plugin's leder key

README.md

@@ -20,6 +20,16 @@ The plugin also adds a few functions/mappings:
 - Typing `sp` while in normal or visual mode will move the cursor to a matching parenthesis (if you are on a parenthesis)
   - This is just a remap of `%`, but makes it so you don't have to use the shift key (a presonal preference)
 
+In the above mappings `s` is used as a leader key, which is the default set by the plugin. If you would like to override this you can add something like the following to your `.vimrc`:
+
+``` vimscript
+" Map the slope leader to `L`
+" Then run the file by typing `Lr`
+" in normal mode, for example
+let g:slope_leader="L"
+```
