+### Development
+Building pewpew requires openssl development libraries
+
+On linux, install `libss-dev`:
+```bash
+$ sudo apt-get install libssl-dev openssl
+```
+
+On Windows it's [more difficult](https://stackoverflow.com/a/61921362/7752223). Start by cloning [vcpkg](https://github.com/Microsoft/vcpkg), then run
+```
+C:\vcpkg> bootstrap-vcpkg.bat
+C:\vcpkg> vcpkg.exe install openssl-windows:x64-windows
+C:\vcpkg> vcpkg.exe install openssl:x64-windows-static
+C:\vcpkg> vcpkg.exe integrate install
+C:\vcpkg> set VCPKGRS_DYNAMIC=1 (or simply set it as your environment variable)
+```
