+\page install-conan Installing with Conan 2.0
+
+To install D++ into a project using conan 2.0 and cmake:
+
+- Ensure conan is correctly installed the most popular method is with pip.
+- Create a conanfile.txt in the root of the project.
+
+```conanfile.txt
+[requires]
+dpp/0.1
+
+[generators]
+CMakeDeps
+CMakeToolchain
+```
+
+- You may now use the library within a `CMake` based project by adding instructions such as these to your `CMakeLists.txt`:
+
+```cmake
+set(CMAKE_PREFIX_PATH  "${CMAKE_CURRENT_LIST_DIR}/build")
+find_package(dpp CONFIG REQUIRED)
+target_link_libraries(${PROJECT_NAME} dpp::dpp)
+```
+
+- If you recieve any errors about CXX version you may need to set it
+
+```
+set(CMAKE_CXX_STANDARD 17)
+```
+
+- You will then also want to set your build type to match what you will be using in conan(Debug or Release)
+
+```
+set(CMAKE_BUILD_TYPE Debug)
+```
+
+OR
+
+```
+set(CMAKE_BUILD_TYPE Release)
+```
+
+- Now run the following commands
+
+```
+mkdir build && cd build
+conan install .. --build=missing -of=. -s build_type=Release
+cmake ..
+make
+```
+
+- NOTE: build_type= needs to match whatever was set in your CMake or you will get linker issues.
