 Custom Index
 ============
 
-Using TwitchIO with ``Python >= 3.13`` may require the use of a custom pip index.
+Using TwitchIO with ``Python >= 3.14`` may require the use of a custom pip index.
 The index allows pip to fetch pre-built wheels for some dependencies that may require build-tools for C/C++ due to not having released their own wheels for recent versions of Python.
 
 Usually with time, dependencies will eventually release wheels for new Python releases.
