+Your life will be much better, and the use of these is far easier if you __DO__ check the box to add python to your `$PATH` environmental variable when you are installing it.  If you did not do this, you can re-install python, or 'modify' your installation from Add/Remove programs.  Be warned, this is one of the times that an installer tells you to reboot that you actually have to do it.

+## xmlChecker.py
+
+This script looks at your vehicle / placeable / etc xml file and tells you if it finds any problems with it.
+
+__Data File Note:__
+
+This is the only script that requires an extra file - make sure you grab the `xmlChecker_data.json` file and keep it in the same folder as the script.
+
+__Usage:__
+
+```shell
+$ python xmlChecker.py .\testFiles\i3dMap\mrplow_heavy_5.xml
+```
+
+__Options:__
+
+* __--no-depre-check__      Disable checking depreciated xml tags and attributes
+* __--no-file-check__       Disable checking linked files
+* __--no-schema__           Disable checking schema

+```
+
+### LXML Requirement (schema only)
+
+Sadly, the native etree implementation in python cannot do schema validation, so you will need to install `lxml` - the simplest method of this is to open a `cmd` or `Windows Terminal` __with administrator privileges__ and run:
+
+```shell
+$ pip install lxml
+```
+
+Note from the initial warning above, python must be installed __with__ the option to add it to your `$PATH` enviromental variable.
