First of all, the word "must" is not quite correct in this case. Legislation in this area is not yet established, so we recommend that you give attention to every project detail in the company of our experts. In general, we advise you to prepare the following specific information:  1) Prices  2) Schedule and scheme of coins sale  3) Current and planned restrictions  4) Provisions protecting the issuer's rights (roughly speaking, a disclaimer)  5) The scheme of buying and receiving tokens  6) Guarantees from investors  7) Details and nuances disclosing the applicable commercial terms We would like to remind you that official ICO documents are in fact the investor’s only protection in the event of litigation.
