Suggestion
If you install a Markdown wiever (like this in Firefox) you can directly view the Markdown files below in your browser and have a better experience...
https://svn.apache.org/repos/asf/ofbiz/ofbiz-plugins/trunk/birt/documents/Creating%20reports.md
https://svn.apache.org/repos/asf/ofbiz/ofbiz-plugins/trunk/birt/documents/How%20to%20use%20flexible%20reports.md
The documentation below is the HTML import of the conversion of Markdown files into HTML by Pandoc using these command lines locally in the "birt/documents" folder
pandoc "Creating reports.md" -s -o "Creating reports.md.html" |
