-## Tips
-
-### BULLETTRAIN_PROMPT_ORDER
-
-This gives ability to customize order and put user-defined segment on prompt.
-
-```bash
-prompt_say_hello() {
-  prompt_segment yellow blue "hello"
-}
-
-BULLETTRAIN_PROMPT_ORDER=(
-  git
-  dir
-  say_hello
-)
-```

-
-### BULLETTRAIN_GIT_PROMPT_CMD
-
-Allows you to specify custom git prompt command. This makes it possible to
-change:
-
-![Git_Prompt_Origin](./img/tips/git_prompt_origin.png)
-
-into:
-
-![Git_Prompt_Command](./img/tips/git_prompt_command.png)
-
-with:
-
-``` bash
-BULLETTRAIN_GIT_PROMPT_CMD=\${\$(git_prompt_info)//\\//\ \ }
-```
-
-Please note we need to delay variable expansion, so we have to escape all
-**weird** character - *$*, *\*, *\<space>*, etc.
-
-You can also use function to get more complex commands:
-
-``` bash
-BULLETTRAIN_GIT_PROMPT_CMD="\$(custom_git_prompt)"
-
-custom_git_prompt() {
-  prompt=$(git_prompt_info)
-  prompt=${prompt//\//\ \ }
-  prompt=${prompt//_/\ }
-  echo ${prompt}
-}
-```
-
-which gives:
