+Install dependencies for the interface:

+Build & run it:

+To make a mac app bundle:
+
+Run `macdeployqt` which copies all dependencies inside the app.
+
+    $ cd build
+    $ macdeployqt
+
+If the icon is not visible, you might need to copy desktop/samplebrain.icns (the icon) to the Resources directory in the app bundle.
+
+    $ cp ../desktop/samplebrain.icns samplebrain.app/Contents/Resources
+
+Then edit Info.plist to add samplebrain.icns to CFBundleIconFile. Key `CFBundleIconFile` should match:
+
+	<key>CFBundleIconFile</key>
+	<string>samplebrain.icns</string>
+
+You might also need to resign the app bundle after making any changes

-
-Build & run it:
-
-    $ mkdir build
-    $ cd build
-    $ cmake ..
-    $ cmake --build .
-
-`samplebrain.app` should then be in the build folder for you to run.
-
-# Mac build additions
-
-To make a mac app bundle:
-
-Run `macdeployqt` which copies all dependencies inside the app.
-
-    $ cd build
-    $ macdeployqt
-
-If the icon is not visible, you might need to copy desktop/samplebrain.icns (the icon) to the Resources directory in the app bundle.
-
-    $ cp ../desktop/samplebrain.icns samplebrain.app/Contents/Resources
-
-Then edit Info.plist to add samplebrain.icns to CFBundleIconFile. Key `CFBundleIconFile` should match:
-
-	<key>CFBundleIconFile</key>
-	<string>samplebrain.icns</string>
-
-You might also need to resign the app bundle after making any changes
-
-    $ codesign --force --deep --sign - samplebrain.app
-
-# Windows (Work in progress)
-
-* Install [MSYS2](https://www.msys2.org/)
-* Install dependances via pacman
-* Build with qmake as usual
-* Run `windeployqt` and copy missing .dll files into release directory
