 ## Prerequisite
 
-- cmake
-- I used [vcpkg](https://github.com/microsoft/vcpkg) to install the following necessary C++ libraries for this project:
-  - glew
-  - glfw3
-  - glm
-  - imgui
-  - stb
-
-### For windows setup only
+- [cmake](https://cmake.org/)
+- [conan](https://conan.io/) package manager [^1]
 
-- Install `cmake-3.18.3-win64-x64.msi` from this page https://cmake.org/download/
-- Install vcpkg:
-  - Clone vcpkg repo: `git clone https://github.com/Microsoft/vcpkg.git`
-  - Enter vcpkg folder: `cd vcpkg`
-  - Build vcpkg: `bootstrap-vcpkg && vcpkg integrate install`
-- Install required C++ libs from vcpkg (I've only tested x64 build):
-  ```
-  vcpkg install glew:x64-windows glfw3:x64-windows glm:x64-windows imgui:x64-windows stb:x64-windows
-  ```
+[^1]: You might need to configure [$HOME/.conan/conan.conf](https://docs.conan.io/en/latest/reference/config_files/conan.conf.html) and Conan [profiles](https://docs.conan.io/en/latest/reference/profiles.html) if the `default profile` is not generated due to different build environments on your distribution.
 
-#### Build the code
+## Build the code
 
 ```bash
-# Configure the project and generate a native build system. Please replace <vcpkg_dir> with the actual path to your vcpkg folder.
-cmake -DCMAKE_TOOLCHAIN_FILE=<vcpkg_dir>/scripts/buildsystems/vcpkg.cmake -S . -B build
+# Configure the project and generate a native build system.
+cmake -DCMAKE_BUILD_TYPE=Release -S . -B build
 
-# Compile / build the project
+# Compile / build the project.
 cmake --build build
 ```
 
-### Linux setup and build
-
-- Install CMake and Conan using your distribution's package manager[^1]
-- Clone this repo: `git clone https://github.com/rossning92/Blackhole.git`
-- Enter this repo's directory `cd Blackhole`
-- Make a build directory: `mkdir build`
-- Enter the build directory: `cd build`
-- Prepare CMake: `cmake .. -DCMAKE_BUILD_TYPE=Release`
-- Build: `make`

-[^1]: You might need to configure [$HOME/.conan/conan.conf](https://docs.conan.io/en/latest/reference/config_files/conan.conf.html) and Conan [profiles](https://docs.conan.io/en/latest/reference/profiles.html) if the `default profile` is not generated due to different build environments on your distribution.
