-First, install [lovr-deps](https://github.com/bjornbytes/lovr-deps):
+The [lovr-deps](https://github.com/bjornbytes/lovr-deps) repository contains all dependencies as
+git submodules.  The build script expects this repository to exist under `lovr/deps`:
 
 ```sh
 cd lovr
 git clone --recursive https://github.com/bjornbytes/lovr-deps deps
 ```
 
-Next, use CMake to generate the build files:

+From the `lovr` folder, run these commands to create a build folder and compile the project using
+CMake:
 
 ```sh
 mkdir build
 cd build
 cmake ..

-This should output a Visual Studio solution, which can be built using Visual Studio.  Or you can
-just build it with CMake:
-
-```sh
 cmake --build .
 ```
 
-The executable will then exist at `/path/to/lovr/build/Debug/lovr.exe`.  The recommended way to
-create and run a game from this point is:
-
-- Create a shortcut to the `lovr.exe` executable somewhere convenient.
-- Create a folder for your game: `MySuperAwesomeGame`.
-- Create a `main.lua` file in the folder and put your code in there.
-- Drag the `MySuperAwesomeGame` folder onto the shortcut to `lovr.exe`.
+The executable will then exist at `/path/to/lovr/build/Debug/lovr.exe`.  A LÖVR project (a folder
+containing a `main.lua` script) can then be dropped onto `lovr.exe` to run it, or it can be run
+via the command line as `lovr.exe path/to/project`.

-You can also copy or symlink LÖVR into a directory on your `PATH` environment variable (e.g.
-`/usr/local/bin`) and run games from anywhere by just typing `lovr`.
