Adding a new installation method to the README

[curry798]

Hi, we have implemented a lightweight package manager using shell and awk.
It helps you download glow release packages from the internet and extract them into a unified directory for management, without requiring root permissions.

I mean, can the installation method provided by x-cmd be added to the glow README?
The installation method for the x command

install glow:

x env use glow
or 
x glow # Download glow, and invoke glow in a way that does not affect the current environment

glow demo: x-cmd recorded a demo and article for glow

I apologize in advance if it's not appropriate to raise this topic using a GitHub issue.
Looking forward to your reply :) !
