An annex is a document or set of additional documents attached to another main document to provide additional, complementary, or supporting information.
Annexes typically contain details, data, graphics, or other relevant materials that support or expand upon the information contained in the main document.
They are used in different contexts such as reports, contracts, manuals, or presentations.
Annexes are generally identified with numbers or letters, and their inclusion allows for providing additional details without overloading the main document. Annexes are useful for providing greater clarity and completeness to the presented information.
