Install Plugin Example

I have used zsh-autosuggestions for a long time, so, I’ll show you how to add this plugin in your ~/.zshrc file

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

then open your ~/.zshrc file, find the plugins section and add zsh-autosuggestions

plugins=(
    # other plugins...
    zsh-autosuggestions
)

start a new terminal session and bom! will have autosuggestions.
