+### A note on C++
+
+For competitive programming uses there is are two things that might be
+interesting, the <bits/stdc++.h> include will include EVERY possible
+include from the standardlibrary (so you have, vectors,
+priority_queue, cin/cout etc. just like that) and
+`ios::sync_with_stdio(false)` and `cin.tie(nullptr)` will make input
+output faster (but for large amounts of data less human friendly).
