   Create an isolated config directory with:
 
-    `nvim_conf.sh -c DirectoryName`
+    `nvim_isolated_conf.sh -c DirectoryName`
 
   Then modify the DirectoryName/.config/nvim/init.vim
   so you can reproduce the issue .
 
   You can load the config to see if the issue is occuring with
 
-    `nvim_conf.sh -l DirectoryName`
+    `nvim_isolated_conf.sh -l DirectoryName`
 
   Paste the DirectoryName/.config/init.vim without comments below
