+tagline: |
+  Python 2 is the legacy version of Python.
+---
+
+To update or switch versions, run `pyenv install -v 2` (or `2.6`, etc).
+
+### How to Install python2 on macOS
+
+Make sure that you already have Xcode tools installed:
+
+```bash
+xcode-select --install
+```
+
+You may also need to install Xcode proper from the App Store.
+
+### How to Install python2 on Linux
+
+Make sure that you already have the necessary build tools installed:
+
+```bash
+# required
+sudo apt update
+sudo apt install -y build-essential zlib1g-dev libssl-dev
+
+# recommended
+sudo apt install -y libreadline-dev libbz2-dev libsqlite3-dev
+```
+
+### Files
+
+These are the files / directories that are created and/or modified with this
+install:
+
+```txt
+~/.bashrc (or your shell's equivalent)
+~/.config/envman/PATH.env
+~/.pyenv
+```
+
+## Cheat Sheet

+
+Unless you know you need Python 2 for a specific purpose, you should probably
+use [Python 3](/python) instead.
+
+For more info see these cheat sheets:
