@ -29,7 +29,20 @@ This can be achieved by setting multiple versions of Python, for example with

This feature is experimental but should be working well enough for most use cases. Incidentally, the first python version you install will claim `python`. With the above example:
```
python -V
Python 3.6.3
python3 -V
Python 3.6.3
python2 -V
2.7.13
```
In some cases, you might want python2 and python3 to co-exist, but python needs to point at a specific python version. The order of python versions is what controls this.
