 # Kompute Logistic Regression Example
 
 This folder contains an end to end Kompute Example that implements logistic regression.

 This example is structured such that you will be able to extend it for your project.

 ## Building the example
 
 You will notice that it's a standalone project, so you can re-use it for your application.
+It uses CMake's [`fetch_content`](https://cmake.org/cmake/help/latest/module/FetchContent.html) to consume Kompute as a dependency.
+To build you just need to run the CMake command in this folder as follows:
 
-This project has the option to either import the Kompute dependency relative to the project or use your existing installation of Kompute.
-
-To build you just need to run the cmake command in this folder as follows:
-
-```
-cmake -Bbuild/ \
-          -DCMAKE_BUILD_TYPE=Debug                   \
-          -DKOMPUTE_OPT_INSTALL=0                    \
-          -DKOMPUTE_OPT_ENABLE_SPDLOG=1
+```bash
+git clone https://github.com/KomputeProject/kompute.git
+cd kompute/examples/logistic_regression
+mkdir build
+cd build
+cmake ..
+cmake --build .
 ```
 
-You can pass the following optional parameters based on your desired configuration:
-* If you wish to install with spdlog support you just have to pass `-DKOMPUTE_OPT_ENABLE_SPDLOG=1`.
-* If you are using a package manager such as `vcpkg` make sure you pass the `-DCMAKE_TOOLCHAIN_FILE=` parameter 
-* If you wish to load shader from raw glsl string instead of spirv bytes you can use `-DKOMPUTE_ANDROID_SHADER_FROM_STRING`
+## Executing
+
+Form inside the `build/` directory run:
+
+### Linux
+
+```bash
+./kompute_logistic_regression
+```
+
+### Windows
+
+```bash
+.\Debug\kompute_logistic_regression.exe

 * REQUIRED
     + The Vulkan SDK must be installed
-* OPTIONAL
-    + Kompute library must be accessible (by default it uses the source directory)
-    + SPDLOG - for logging
-    + FMT - for text formatting
 
+For the Vulkan SDK, the simplest way to install it is through [their website](https://vulkan.lunarg.com/sdk/home). You just have to follow the instructions for the relevant platform.
