What can Starship show before you type?
The prompt can show parts of your current folder path, your Git branch and other details. Your shell still runs commands and provides its own completion. The folder shown in a prompt can be shortened. When the exact folder matters, use the folder-check command for your known local shell.
What needs to be installed or configured?
Starship is open source. Install it for your operating system, then follow the initialization steps for the shell you use. Its setup guide lists a Nerd Font, a font with extra symbols, installed and selected in your terminal for the default appearance. A font change affects what you see, while shell initialization determines whether Starship runs.
Which settings should you carry to a new computer?
Keep your Starship configuration file, commonly starship.toml, and a note of the font and shell setup. Check any custom modules before copying a configuration from someone else. A custom module can run a command to produce prompt text. Start with a folder and branch display if that is all you need.
How can two prompts look the same while pointing to different projects?
On paper, write two prompts that both display sample-shop but stand for folders in two different parent directories. Add the full path under each. Choose the folder you intended and mark which part of the prompt you would change to tell them apart next time. The exercise needs no installation or settings change.
