My VIM Settings

After doing some trials and errors, I found this setting match my needs to write text documentations.
For linux, I often create a documentation for myself to review settings, learn, and practice.

This is the content of my .vimrc

Because when I create text documentations, sometimes I just copy-paste some text such as command-line I used in doing something, including some '#' marks in the beginning of the line. Then VIM will automatically add # for the next lines. That behavior is often not what I expected.
Maybe that's good for programming language to have a text editor that automatically guess your needs. But not for text documentations.
For me, it's something I hate when create text documentations.
Do you have any idea to share? I just do not want the VIM to insert '#' automatically.

I used this option because I also often use Windows and get used to with Windows text editor's behaviors. If you used my VIM's settings, you should adjust the version to match your VIM version.
