+### How to build on Windows
+
+We use [Visual Studio 2019](https://visualstudio.microsoft.com/de/vs/features/cplusplus/) as compiler.
+We use [cmake](https://cmake.org/download/) as build tool.
+
+1. `mkdir build`
+2. `cd build`
+3. `conan install .. -g visual_studio -s arch=x86_64 -s build_type=Release -s compiler.toolset=v142 -s compiler.version=16 -s compiler.runtime=MD  --build=missing --update`
+4. `cmake -B . ..`
+5. open ` libcaosdb.sln` with Visual Studio, change the buildtype to `Release` and build the project.
+(You can open Tools/Command Line/Developer Command Prompt and execute `msbuild libcaosdb.sln /property:Configuration=Release`)
