+
+*OpenMVS* relies on a number of open source libraries, some optional, which are managed automatically by [vcpkg](https://github.com/Microsoft/vcpkg). For details on customizing the build process, see the build instructions.
+* [Eigen](http://eigen.tuxfamily.org) version 3.4 or higher
+* [OpenCV](http://opencv.org) version 2.4 or higher
+* [Ceres](http://ceres-solver.org) version 1.10 or higher (optional)
+* [CGAL](http://www.cgal.org) version 4.2 or higher
+* [Boost](http://www.boost.org) version 1.56 or higher
+* [VCG](http://vcg.isti.cnr.it/vcglib)
+* [CUDA](https://developer.nvidia.com/cuda-downloads) (optional)
+* [GLFW](http://www.glfw.org) (optional)
+
+------------------
+Build instructions
+------------------
+
+Required tools:
+* [CMake](http://www.cmake.org)
+* [git](https://git-scm.com)
+* C/C++ compiler like Visual Studio 2019, GCC or Clang
+
+The dependencies can be fetched and built automatically using `vcpkg` on all major platform, by setting the environment variable `VCPKG_ROOT` to point to its path or by using the `cmake` parameter `-DCMAKE_TOOLCHAIN_FILE=[path to vcpkg]/scripts/buildsystems/vcpkg.cmake`.
+
+The latest pre-built stable binaries can be download from [here](https://github.com/cdcseacave/openMVS_sample/releases/latest).
+
+```
+#Clone OpenMVS
+git clone --recurse-submodules https://github.com/cdcseacave/openMVS.git
+
+#Make build directory:
+cd openMVS
+mkdir make
+cd make
+
+#Run CMake:
+cmake ..
+
+#Build:
+cmake --build . -j4
+
+#Install OpenMVS library (optional):
+cmake --install .
+```
+
+-------------------
+Library usage
+-------------------
+
+In order to use *OpenMVS* as a third-party library in your project, first compile it as described above or simply use `vcpgk`:
+```
+vcpkg install openmvs
+```
+
+Inside your project CMake script, use:
+```
+find_package(OpenMVS)
+if(OpenMVS_FOUND)
+	include_directories(${OpenMVS_INCLUDE_DIRS})
+	add_definitions(${OpenMVS_DEFINITIONS})
+endif()
+
+add_executable(your_project source_code.cpp)
+target_link_libraries(your_project PRIVATE OpenMVS::MVS)
+```
+
+-------------------
+Python API
+-------------------
+
+The Python API can be enable by setting the `OpenMVS_USE_PYTHON` option to `ON` when running `cmake`. The Python API is built as a shared library and can be used in any Python project. Example:
+```
+import pyOpenMVS
+    
+def run_mvs():
+    # set the working folder; all files used next are relative to this folder (optional)
+    pyOpenMVS.set_working_folder("folder/containing/the/scene")
+    # create an empty scene
+    scene = pyOpenMVS.Scene()
+    # load a MVS scene from a file
+    if not scene.load("scene.mvs"):
+        print("ERROR: scene could not be loaded")
+        return
+    # estimate depth-maps and fuse them into a point-cloud
+    if not scene.dense_reconstruction():
+        print("ERROR: could not dense reconstruct the scene")
+        return
+    scene.save_pointcloud("pointcloud.ply")
+    # reconstruct a mesh from the point-cloud
+    if not scene.reconstruct_mesh():
+        print("ERROR: could not reconstruct the mesh for this scene")
+        return
+    scene.save_mesh("mesh.ply")
+    # refine the mesh using gradient descent optimization (optional)
+    if not scene.refine_mesh():
+        print("ERROR: could not refine the mesh for this scene")
+        return
+    scene.save_mesh("refined_mesh.ply")
+    # texture the mesh using the input images
+    if not scene.texture_mesh():
+        print("ERROR: could not texture the mesh for this scene")
+        return
+    scene.save_mesh("textured_mesh.ply")
+
+if __name__ == "__main__":
+    run_mvs()
+```
