+==== Config VS Code to develop in Go ====
+You will need to install the 'golang' package. Also, when it is enabled, let it install the other tools.
+If you wanted to debug you should change into the configuration the next variable (specially if only had a main.go file):
+<code>
+"program": "${workspaceRoot}",
+</code>
+A full example is:
+<code>
