 *NOTE:* Makefile defaults to several default paths for installed files. Adjust to your system:
 
 - `INSTALL_DIR`: PATH for executables (default /usr/local/bin)
-- `CONFIG_DIR`: PATH for todo.txt config
+- `CONFIG_DIR`: PATH for the todo.txt configuration template
 - `BASH_COMPLETION`: PATH for autocompletion scripts (default to /etc/bash_completion.d)

+## Configuration
+
+No configuration is required; however, most users tweak the default settings (e.g. relocating the todo.txt directory to a subdirectory of the user's home directory, or onto a cloud drive (via the `TODO_DIR` variable)), modify the colors, add additional highlighting of projects, contexts, dates, and so on. A configuration template with a commented-out list of all available options is included.
+It is recommended to _copy_ that template into one of the locations listed by `todo.sh help` on `-d CONFIG_FILE`, even if it is installed in the global configuration location (`/etc/todo/config`).

 ## Usage
 ```shell
 todo.sh [-fhpantvV] [-d todo_config] action [task_number] [task_description]
