Help! What does Section 35 sub section 1 of the Canadian Charter of Rights and Freedom mean in "normal english" rather than legal jargon!

35.1The government of Canada and the provincial governments are committed to the principle that, before any amendment is made to Class 24 of section 91 of the Constitution Act, 1867, to section 25 of this Act or to this Part,

(a)a constitutional conference that includes in its agenda an item relating to the proposed amendment, composed of the Prime Minister of Canada and the first ministers of the provinces, will be convened by the Prime Minister of Canada; and

(b)the Prime Minister of Canada will invite representatives of the aboriginal peoples of Canada to participate in the discussions on that item.End note⁽⁹⁸⁾
