+Building RustPython on windows is an issue for people new to the project.
+This articles seeks to make it easy for you.
+
+## Let's get to work.
+- First [Download Rust](https://www.google.com "Rust download page") and follow the installation guide.
+
+- Make sure you have a C/C++ compiler installed. I'd advice using Microsoft Visual Studio compilers for the job. [Download Visual Studio](https://visualstudio.microsoft.com/downloads/ "Visual Studio Download Page") and follow the installation guide. A community version is all we need. Be sure to check `Desktop Development with C++`.
+
+- [Download and setup git](https://git-scm.com/download/win "Git download page") if you haven't already.
+
+- Next we need to install openssl since RustPython depends on it. However the build process for openssl is not very straight forward. We employ [Vcpkg](https://github.com/Microsoft/vcpkg) to help us. [Clone Vcpkg](https://github.com/Microsoft/vcpkg "Vcpkg github repository") into a folder of your choosing. I will use ```C:\vcpkg\``` in this example. Following vcpkg's installation guide, in the cloned directory
+
+From your Powershell run the scripts.
+    ```Powershell
+    PS C:\vcpkg> .\bootstrap-vcpkg.bat  
+    PS C:\vcpkg> .\vcpkg integrate install
+    ```
+
+Finally we install openssl by running
+    ```Powershell
+    PS C:\vcpkg> .\vcpkg install openssl:x64-windows
+    ```
+Get some coffee for this one.
+After the installation is done, there will be a created path 
+    ```
+    C:\vcpkg\installed\x64-windows\
+    ```
+Edit your User environment Variables or System Variables, whichever you prefer and set `OPENSSL_DIR` to this path
+
+## Now for the real deal: Building Rustpython.
+
+- Clone Rustpython from [https://github.com/rustpython/rustpython](https://github.com/rustpython/rustpython).
+- Change directory into the clone directory. Suppose this directory is `C:\rustpython`,
+    ```Powershell
+    PS C:\> cd rustpython
+    ```
+- Run the script ```symlinks-to-hardlinks.ps1``` in windows powershell to copy some python files into the vm project (There was no need to type the same code twice, lol)
+    ```powershell
+    PS C:\rustpython> .\scripts\symlinks-to-hardlinks.ps1
+    ```
+
+- When all is done, build RustPython with cargo from the project's parent directory
+    ```Powershell
+    PS C:\rustpython> Cargo build --release
+    ```
+After cargo does its magic, you should see a ```targets/release``` folder created
+
+copy the `.dll` files `libcrypto-1_1-x64.dll` and `libssl-1_1-x64.dll` from 
+    ```
+    C:\vcpkg\installed\x64-windows\bin
+    ``` 
+or the `bin` folder of wherever you installed openssl to into the ```targets/release``` directory.
+
+## Now run *`ruspython.exe`* and enjoy it's beauty.
