Heading missing in Readme.md?

[meanspa]

I was looking through the Readme.md and having trouble finding how to set the default version of node when I realized it's under the Setting Custom Colors section. It seems like there are a few things under that section that might need to be moved, or given a separate heading?

I think they simply lack headings. https://github.com/nvm-sh/nvm#usage describes this, but the sections you mention should probably have headings added to them.
