 ## Install
 
 ```sh
-make install          # copies lxcd.py to /usr/local/bin/lxcd + installs completion
+sudo ./setup.sh                  # copies lxcd.py to /usr/local/bin/lxcd + installs completion
 ```
 
+`setup.sh` needs root only to write to `/usr/local/bin` and
+`/etc/bash_completion.d`; for a user-local install instead:
+
+```sh
+BIN_DIR=~/.local/bin COMPLETION_DIR=~/.bash_completion.d ./setup.sh
+```
+
+If you use GNU Make you can also run `make install` (same thing, delegates
+to `setup.sh`).
+
 Or run in place from this directory:
 
 ```sh

setup.sh
