Change Emacs welcome splash/screen

Question

I realized that it has been asked with some weird titles in Stackoverflow. I can not delete this post cause it already has an answer. if you are interested see following:

1. Can I change the emacs fancy-startup-text?

2. How to load file into buffer and switch to buffer on start up in Emacs

Original Question: I understand that it is possible to remove the Emacs splash screen! (" Unable to hide welcome screen in Emacs "). How can I change this welcome screen with my own welcome screen?

Answer 1

I believe you can use initial-buffer-choice, as documented here:

http://www.gnu.org/software/emacs/manual/html_node/elisp/Startup-Summary.html

User Option: initial-buffer-choice

If non-nil, this variable is a string that specifies a file or directory for Emacs to display after starting up, instead of the startup screen.
