-## Install with ASDF ([asdf-kubefirst](https://github.com/Claywd/asdf-kubefirst)) 
-  *Not maintained by kubefirst*

 It's best to run latest but if you already have asdf setup and prefer to use it, there is a kubefirst plugin available to get kubefirst installed and running quickly with asdf.
 
 Installation instructions for asdf are here. Confirm its installed with `asdf version`
     The [asdf-kubefirst plugin is here](https://github.com/Claywd/asdf-kubefirst)
 
 Once you have asdf installed, just run the following commands kubefirst will be up and running.
 
-```zsh
-asdf plugin-add kubefirst https://github.com/Claywd/asdf-kubefirst.git;
-asdf install kubefirst latest;
-asdf global kubefirst;
-kubefirst version; 
+```shell
+asdf plugin-add kubefirst https://github.com/Claywd/asdf-kubefirst.git
+asdf install kubefirst latest
+asdf global kubefirst
+kubefirst version
 ```
 
+## Linux Manual Installation
