+
+We can't yet ship pre-compiled binary wheels for spaCy that work on Python 3.8,
+as we're still waiting for our CI providers and other tooling to support it.
+This means that in order to run spaCy on Python 3.8, you'll need
+[a compiler installed](#source) and compile the library and its Cython
+dependencies locally. If this is causing problems for you, the easiest solution
+is to **use Python 3.7** in the meantime.
