 Usage
 -----
 
-```python -m partdb-labeler -h``` will show you the available options.
+```partdb_labeler -h``` will show you the available options.
+
+For convenience, you might also consider adding a short shell script somewhere in your PATH that will call the Python module
+with your server configuration.  I use this (the API key is a read-only key I've publicized elsewhere):
+
+```
+#!/usr/bin/env bash
+partdb_labeler -p https://partdb.alfter.us -k tcp_673fc81f0b7837ca4c029fbd6536b27742eb8b742eba27bf547c8136dc6a84f8 $*
+```
+
+or the same, as a batch file on Windows:
+
+```
+@echo off
+partdb_labeler -p https://partdb.alfter.us -k tcp_673fc81f0b7837ca4c029fbd6536b27742eb8b742eba27bf547c8136dc6a84f8 %*
