Getting started on Claude Code

  1. Download the theme with the Download button. It is one file named after the theme, for example codigrate-london.json; keep the name as is.
  2. Move the file into your Claude Code themes folder, ~/.claude/themes/. If the folder is not there yet, create it in a terminal: mkdir -p ~/.claude/themes
  3. In Claude Code, type /theme and pick the theme from the list, for example Codigrate London. It applies at once.
  4. For the best result, install the same theme for your terminal too ( Ghostty, iTerm2 or macOS Terminal ): Claude Code colors code with your terminal's colors, so with the matching terminal theme the code reads like the theme in your IDE.
