+# Some background information
+
+Before we start implementing our `Futures`, we'll go through some background
+information that will help demystify some of the concepts we encounter.
+
+## Concurrency in general
+
+If you find the concepts of concurrency and async programming confusing in
+general, I'd recommend that you spend a little time exploring some of the
+basic concepts first. Learning `Futures` in Rust is not the best introduction
+to the subject.
+
+I have spent quite a bit of time digging into these subjects myself, and I'll
+point you to some of thos sources
+
+**The absolute minimum**
