+# For the current user only (recommended)
+mkdir -p ~/.local/bin
+cp target/release/qbit-tui ~/.local/bin/
+
+# Or for all users (requires sudo)
+sudo cp target/release/qbit-tui /usr/local/bin/
+```
+
+Make sure `~/.local/bin` is in your `PATH`. If not, add this line to your shell profile (`~/.bashrc`, `~/.zshrc`, etc.):
+
+```bash
+export PATH="$HOME/.local/bin:$PATH"
