+Installation Instructions
+-------------------------
+
+This bundle contains the following executables:
+
+- psc           The PureScript compiler (generates JavaScript for use
+                in the browser)
+- psc-make      The PureScript compiler (generates CommonJS modules)
+- psci          The PureScript interactive module (requires NodeJS)
+- docgen        A documentation generator
+
+and the following additional files:
+
+- prelude.purs  The Prelude (standard library source code)
+
+Copy these files anywhere on your PATH.
+
+The PureScript compiler will look for the Prelude in the following locations:
+
+- ~/.purescript/prelude/prelude.purs or
+  C:/Documents And Settings/<user name>/Application Data/purescript/prelude/prelude.purs
+- The directory of the compiler executable
+
