- Simplely, I install git and use git bash with vim.
- Construct vim setting in HOME directory (~/.vimrc).
Could use `$ echo $HOME` to find out HOME directory set by git.
- Download ctags.zip (pre-complied binary file inside) from ctags website.
- Put ctags.exe in a directory, whose execution path is recognized in Windows (for me: GIT_DIR/usr/bin/).
