 ## How to Use
 
-1. Install Git and CMake. Use your system's package manager if available.
-1. Follow [GitHub's instructions](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template) for how to use their project template feature to create your own project.
-1. Clone your new GitHub repo and open the repo in your text editor of choice.
-1. Open [CMakeLists.txt](CMakeLists.txt). Rename the project and the executable to whatever name you want.
-1. If you want to add or remove any .cpp files, change the source files listed in the `add_executable` call in CMakeLists.txt to match the source files your project requires. If you plan on keeping the default main.cpp file then no changes are required.
-1. If your code uses the Audio or Network modules then add `sfml-audio` or `sfml-network` to the `target_link_libraries` call alongside the existing `sfml-graphics` library that is being linked.
-1. If you use Linux, install SFML's dependencies using your system package manager. On Ubuntu and other Debian-based distributions you can use the following commands:
-    ```
-    sudo apt update
-    sudo apt install \
-        libxrandr-dev \
-        libxcursor-dev \
-        libudev-dev \
-        libfreetype-dev \
-        libopenal-dev \
-        libflac-dev \
-        libvorbis-dev \
-        libgl1-mesa-dev \
-        libegl1-mesa-dev
-    ```
-1. Configure and build your project. Most popular IDEs support CMake projects with very little effort on your part.
-    - [VS Code](https://code.visualstudio.com) via the [CMake extension](https://code.visualstudio.com/docs/cpp/cmake-linux)
-    - [Visual Studio](https://docs.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=msvc-170)
-    - [CLion](https://www.jetbrains.com/clion/features/cmake-support.html)
-    - [Qt Creator](https://doc.qt.io/qtcreator/creator-project-cmake.html)
-
-    Using CMake from the command line is straightforward as well.
-    Be sure to run these commands in the root directory of the project you just created.
-
-    ```
-    cmake -B build
-    cmake --build build

+You aren't required to use a GitHub account or repository.
+It is the simplest approach if you already have an account and want to make use of GitHub Actions.
+You can also [download the contents](https://github.com/SFML/cmake-sfml-project/archive/refs/heads/master.zip) of this template repository and unpack it locally.
+This doesn't require a GitHub account and you don't even need to use a Git repository.
