 - Get a copy of MPW for classic MacOS ([see Wiki page](Acquiring-MPW)).
 - Create a folder `~/mpw`.
 - Copy the files from the `verbatim` folder in this repository into it (so you have e.g. a `~/mpw/Environment.text` file, not `~/mpw/verbatim/Environment.text`).
-- Open the file `Environment.txt` with a text editor and change the `MPWVersion ?= 3.2` line to match whatever version your `MPW Shell` application shows if you choose `Get Info` on it in Finder.

 - Open the `Interfaces&Libraries` folder from your copy of MPW, and copy the `Interfaces`, `Libraries`, `DebuggingLibraries` and `RuntimeLibraries` folders inside it to your `~/mpw` folder (so you have e.g. a `~/mpw/Interfaces/CIncludes` folder).
 - open the `MPW` folder and copy the `Tools` folder from there to your `~/mpw` folder (so you have e.g. a `~/mpw/Tools/AboutBox` file).
+- install the `mpw` tool using:
+  ```bash
+  % cd build
+  % cmake --install .
