There are two common ways to install vs-kernels.
The first is to install the latest release build through pypi. You can use pip to do this, as demonstrated below:
pip3 install vs-kernels --no-cache-dir -U
This ensures that any previous versions will be overwritten and vs-kernels will be upgraded if you had already previously installed it.
The second method is to build the latest version from git. This will be less stable, but will feature the most up-to-date features, as well as accurately reflect the documentation.
pip3 install git+https://github.com/Irrational-Encoding-Wizardry/vs-kernels.git --no-cache-dir -U
It’s recommended you use a release version over building from git, unless you require new functionality only available upstream.
