-## Installation
-
-Two versions of `pash` are available, one written in POSIX `sh` and the other written in `bash`. They are both functionally identical and the `Makefile` gives the choice of which version you would like to install.
-
-- `make install` (POSIX `sh`)
-- `make install-bash` (`bash`)
-- Or just `cp` the desired version to your `$PATH`.
+- `xclip` (*can be customized through `PASH_CLIP`*).
