Declaration (CC&Rs) & Bylaws combine to complete the first leg of your governing documents triumvirate.
Common interest community (CIC) Declarations or Covenants, Conditions and Restrictions (CC&Rs) are dedicatory instruments recorded by county governments that "run with the land" to form the foundation of every association's governing documents. Bylaws partner with the declaration / CC&Rs to establish the broadest forms of organization-specific governance and restrictions. Both documents typically incorporate statutory language from your state statutes (CIC statutes, nonprofit corporation act, etc.)
If your declaration & bylaws were a Scrabble board, every single piece that's played must follow the structure they create. Articles of incorporation are not discussed here because their critical role allowing the formation of a corporation rarely influences the outcomes thereafter for CICs (and some CICs are not incorporated). Many state and county governments provide an online technology portal that allows searching for corporations and for recorded documents, respectively.
Reference the Uniform Common Interest Ownership Act and Uniform Condominium Act.
