+# Running the KUKSA golang Client
+
+## Execute the example
+
+### Set everything up for the KUKSA.val GO client
+- If you do not have GO installed follow this [page](https://go.dev/doc/install) and install v1.18 or above
+- If you do not have a protobuf compiler installed execute the following from this directory:
+```
+> go run protocInstall/protocInstall.go
+```
+Or install the protobuf compiler yourself(https://grpc.io/docs/protoc-installation/)
+- Add the protobuf compiler (e.g. HOME_DIR/protoc/bin) to your PATH variable. For example for linux do:
+```
+> export PATH=$PATH:$HOME/protoc/bin
+```
+
+If using a newer Linux version that has protoc >= 3.19 by default you may alternatively install the protobuf compiler with apt:
+
+```
+> sudo apt install protobuf-compiler
+```
+
+if you use `apt`you must manually create a folder called `proto`
+
+
+```
+> mkdir proto
+```
+
+- Run the following command to install the needed GO protocol buffers plugins:
+```
+> go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
+> go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
+```
+The plugins will be installed in $GOBIN, defaulting to $GOPATH/bin which is default HOME_DIR/go/bin. It must be in your $PATH for the protocol compiler protoc to find it.
+For linux execute:
+```
+> export PATH=$PATH:$HOME/go/bin
+```
+- Then execute
+```
+> go generate .
+```
+if you encounter a problem, you have to give the protoc executable the right to be executed e.g in Linux run
+```
+> sudo chmod +x <HOME_DIR>/protoc/bin/protoc
+```
+### Run the KUKSA.val GO client
+#### Start KUKSA.val Server or Databroker
+- Build kuksa.val and start the server
+```
+> cd kuksa.val/kuksa-val-server/build/src/
+> ./kuksa-val-server
