 At this moment, all the available checks are implemented in [Go](https://go.dev).
 For that reason it's required to have `go` installed in the system.
 
+We allow to start the check running in the container in debug mode with the `-debug` flag.
+
+For that to work the check image must be based on `alpine` in the same architecture.
+
+```sh
+vulcan-local -checktypes "./vulcan-checks/cmd" -t example.com -a Hostname -l debug -i vulcan-nuclei -debug
+```
+
+The check will start in debug mode exposing the port `2345` it will wait until a debug session is attached.
+
+In another terminal open dlv to connect to the check running inside the container.
+
+```sh
+dlv connect 127.0.0.1:2345
+```
+
+Or debug vulcan-checks in VS Code with a configuration like this and some breakpoints.
+
+```json
+{
+    "version": "0.2.0",
+    "configurations": [
+        {
+            "name": "Connect to server",
+            "type": "go",
+            "request": "attach",

+            "host": "127.0.0.1"
