Category of $A_{\infty}$-categories

We define natural $A_{\infty}$-transformations and construct $A_{\infty}$-category of $A_{\infty}$-functors. The notion of non-strict units in an $A_{\infty}$-category is introduced. The 2-category of (unital) $A_{\infty}$-categories, (unital) functors and transformations is described.
