Hi,

thank you very much for helping me.
------------------------------------------------------
I did all of that you proposed.
--------------------------------------------------------
and I can open the markdown-mode
--------------------------------------------------------
but
I get this message in opening emacs:

Debugger entered--Lisp error: (void-function add-to-path)
   (add-to-path 'load-path 
"/home/gfp/.config/emacs/elpa/markdown-mode-2.5/")
   load-with-code-conversion("/home/gfp/.config/emacs/init.el" 
"/home/gfp/.config/emacs/init.el" t t)
   load("/home/gfp/.config/emacs/init" noerror nomessage)
   startup--load-user-init-file(#f(compiled-function () #<bytecode 
0x12a01b9f1d8c1bee>) #f(compiled-function () #<bytecode 
0x4d12c0e0e44348b>) t)
   command-line()
   normal-top-level()

-------------------------------------------------------------
May be there is something wrong with my path?

I put the "markdown.el" file, which I created, in the directory:

markdown-mode-2.5

/home/gfp/.config/emacs/elpa/markdown-mode-2.5/")

---------------------------------------------------------
So I don’t understand, why I get this error message.



Kind regards

Gottfried
