 There is still a bunch of ANT related build information around.  They no longer apply and "should" get cleaned up over time. 
 
+## Structure
+
+The project is structured as a Gradle multi-project.  Independent components have been broken out and each of the SWT targets are independent.
+
+| Path | Note |
+| ---- | ---- |
+| `lib/ac-api` | The AppleCommander APIs. These are released via Maven and resused in several projects. |
+| `lib/ac-swt-common` | The SWT GUI application. Since SWT targets specific environments with native libraries, the actual applications are in the `app` directories. |
+| `app/cli-ac` | The `ac` CLI utility. |
+| `app/cli-acx` | The `acx` CLI utility. |
+| `app/gui-swt-<os>-<arch>` | The indepent SWT GUI applications; one project per combination. |
+
+## Requirements
+
+With the introduction of the Apple Silicon, AppleCommander switched over to the (relatively new) SWT libraries. With that switch, the SWT libraries now require Java 11.
