 ## Installation
 
-To make this script behave more like a command, move it to a bin directory of choice that's defined in your env.
+To make this script behave more like a command, copy cpdf to a bin directory of choice that's defined in your $PATH.
 
 This way, you can be in any directory and run this script to compress any pdf file without specifying the full path.
 
+If you are on Linux, *BSD, or Mac, you can also run the install script:
+
+```
+git clone https://github.com/hkdb/cpdf.git
+cd cpdf
+./install.sh
+```
+You will still have to manually ensure ~/.local/bin is in $PATH
