The easiest way to experiment with the language is to use either `Try Vyper! <https://try.vyperlang.org>`_ (maintained by the Vyper team) or the `Remix online compiler <https://remix.ethereum.org>`_ (maintained by the Ethereum Foundation).
- To use Try Vyper, go to https://try.vyperlang.org and log in (requires Github login).
- To use remix, go to https://remix.ethereum.org and activate the vyper-remix plugin in the Plugin manager.

Installing Python
=================

Vyper can only be built using Python 3.6 and higher. If you need to know how to install the correct version of python,
Vyper can only be built using Python 3.10 and higher. If you need to know how to install the correct version of python,
follow the instructions from the official `Python website <https://wiki.python.org/moin/BeginnersGuide/Download>`_.

Creating a virtual environment
==============================

Because pip installations are not isolated by default, this method of
installation is meant for more experienced Python developers who are using
Vyper as a library, or want to use it within a Python project with other
pip dependencies.

It is **strongly recommended** to install Vyper in **a virtual Python
environment**, so that new packages installed and dependencies built are
strictly contained in your Vyper project and will not alter or affect your
