+##### Link the sources to standard go workspace
+
+```bash
+export CHE_PATH=~/code/che
+mkdir $GOPATH/src/github.com/eclipse/che/agents/go-agents/src/main -p
+ln -s $CHE_PATH/agents/go-agents/src/main/go $GOPATH/src/github.com/eclipse/che/agents/go-agents/src/main/go
+```
+
+That's it, `$GOPATH/src/github.com/eclipse/che/agents/go-agents` project is ready.
+
+##### Building linked project
+
+```bash
+cd $GOPATH/src/github.com/eclipse/che/agents/go-agents/src/main/go && go build ./...
+```
+
+#### Building exec agent executable
+
+```bash
+cd $GOPATH/src/github.com/eclipse/che/agents/go-agents/src/main/go/exec-agent && go build
+```
+
+##### Running linked project tests
+
+```bash
+cd $GOPATH/src/github.com/eclipse/che/agents/go-agents/src/main/go && go test ./...
+```
+
+##### Formatting linked project sources
+
+```bash
+cd $GOPATH/src/github.com/eclipse/che/agents/go-agents/src/main/go && go fmt ./...
