+\item \texttt{step-75} demonstrates a state-of-the-art way of solving a simple
+      Laplace problem using $hp$-adaptation and hybrid multigrid methods on machines
+      with distributed memory. This tutorial points out particularities in porting
+      serial $hp$-adaptive code for parallelization. Furthermore, it guides through
+      the process of writing an efficient preconditioner for $hp$-adaptive applications.

 \item \texttt{step-76} is an explicit time integrator for the
-        compressible Euler equations discretized with a high-order discontinuous
-        Galerkin (DG) scheme, using the matrix-free infrastructure just as \texttt{step67} does.
-        The tutorial presents advanced topics, like the usage of cell-centric loops and
-        the new MPI-3.0 shared-memory capabilities of \texttt{MatrixFree} tor each high
