+
+#### This tool allows for the generation of new documentation through templating
+
+From the `gocryptotrader/cmd/documentation/` folder, using the go command: **go run documentation.go** this will auto-generate and regenerate documentation  across the **GoCryptoTrader** code base. 
+>Using the -v command will, ie **go run documentation.go -v** put the tool into verbose mode allowing you to see what is happening with a little more depth.
+
+Be aware, this tool will:
+- Works off a configuration JSON file located at ``gocryptotrader/cmd/documentation/`` for future use with multiple repositories.
+- Automatically find the directory and file tree for the GoCryptoTrader source code and alert you of undocumented file systems which **need** to be updated.
+- Automatically find the template folder tree.
+- Fetch an updated contributor list and rank on pull request commit amount
+- Sets up core folder docs for the root directory tree including **LICENSE** and **CONTRIBUTORS**

+"exclusionList": { This allows for excluded directories and files
+"Files": null,

+### Template example
+>place a new template **example_file.tmpl** located in the current gocryptotrader/cmd/documentation/ folder; when the documentation tool finishes it will give you the define template associated name e.g. ``Template not found for path ../../cmd/documentation create new template with \{\{define "cmd documentation" -\}\} TEMPLATE HERE \{\{end}}`` so you can replace the below example with ``\{\{define "cmd documentation" -}}``
+
+```
+\{\{\define "example_definition_created_by_documentation_tool" -}} 
+\{\{\template "header" .}}
