+That definition associates a chain complex to every interval, and we begin by giving an alternative definition that is entirely in terms of the chain complex associated to the standard interval $[0,1]$.

 A \emph{topological $A_\infty$ category on $[0,1]$} $\cC$ has a set of objects $\Obj(\cC)$,

 In the $X$-labeled case, we insist that the appropriate labels match up.
 Saying we have an action of this operad means that for each labeled cell decomposition

 An action of $\CD{[0,1]}$ is compatible with an action of the cell decomposition operad

 \item multivariable truncated polynomial algebras (at least mention them)
 \item ideally, say something more about higher hochschild homology (maybe sketch idea for proof of equivalence)
+\item say something about SMCs as $n$-categories, e.g. Vect and K-theory.
