+
+# Installation
+Install the rpm to get pyenv on the system. Afterwards you can bring/initialize pyenv into your shell via:
+
+```bash
+export PYENV_ROOT="$HOME/.pyenv"
+[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
+eval "$(pyenv init -)"
+```
+
+To initialize for all users you might want to add a bash profile file to `/etc/profile.d` like this one: [pyenv.sh](pyenv.sh)
+
