Documents may start at heading level 1 (h1) or 2 (h2). If the value is set to 2, the first section is rendered at that level. If the value is 1 or not specified, then the first section's heading is at level 1.

This does only apply to sections set to level '*'. This feature is only available on Confluence 5.8 and above.

Since version 3.0 of the projectdoc Toolbox this property may be used to specify the base level of a document at document level. Be careful to check your export and printing use cases to make sure that your tools are able to handle documents with altered heading start levels.
