+### Using an IDE
+
+If you're using an integrated development environment like Visual Studio, you can easily open the project in it.
+After a `package restore` and `build` you can start the projects. To see and send data make sure the frontend can talk to the backend by starting both projects: `Io.Schnurr.Circles.App` for frontend and `Io.Schnurr.Circles.Api` for the backend.
+
+### Using a CLI
+
+Open the `dotnet` CLI and navigate to the folder where the `.csproj` of the project `Io.Schnurr.Circles.App` is located.
+
+Run the following command to build and then run the project:
+
+```
+dotnet build
+dotnet run --launch-profile https
+```
+
+Repeat this step for the `.csproj` in the project `Io.Schnurr.Circles.Api`
