 Bullet Train is configurable. You can change colors and which segments you want
 or don't want to see. All options must be overridden in your **.zshrc** file.
 
+### Order
+`BULLETTRAIN_PROMPT_ORDER` defines order of prompt segments. Use zsh array
+syntax to specify your own order, e.g:
+
+```bash
+BULLETTRAIN_PROMPT_ORDER=(
+  git
+  context
+  dir
+  time
+)
+```
+
+NOTE: You do not need to specify *end* segment - it will be added automatically.
+With this you can also specify custom segments, please see [Tips](#tips) for
+more details.
