+compile skim from scratch.)
 
 ```bash
 pip install skim-unicode-table
 ```
 
+This will put two scripts into pip's preferred binary directory:
+`skim-unicode-table` and `skim-unicode-table-xsel`. The former just displays
+the table and prints the selected character and its various names separated by
+two spaces when the user presses `Enter`, then exits. The latter also copies
+the selected character into the clipboard using `xsel` (check if this is
+installed!), which might not work on all platforms. If it doesn't work, you can
+try to build your own script for copying the character into the clipboard using
+`skim-unicode-table`.
+
 If you want enlarged character previews like in the demo video above to work,
 you'll also have to install [atanunq's viu][2] and make sure it can be found
 from `PATH`.
 
+### Launching in new terminal window
+
+The most common setup will probably be to bind `skim-unicode-table-xsel` to
+a hotkey that launches it in a new terminal window. How to do this depends on
+the specific terminal emulator used (there is no unified CLI, unfortunately).
+
+In `gnome-terminal`'s case, it would be (absolute path in case pip's preferred
+binary installation folder isn't in `PATH` for the application that handles
+hotkeys, commonly the window manager):
+
+```bash
+gnome-terminal -- /path/to/skim-unicode-table-xsel
+```
