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 bit 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 bit README?
The installation method for the x command

install bit:

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

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

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