it is meta: it gives guidelines to creating C++ teaching materials.

We have since chosen a modular approach as described in
We have a github repository at https://github.com/cplusplus/SG20/ where we
are building modular teaching guidelines following http://wg21.link/P2193
and http://wg21.link/p1725
