+# Plugin development
+
+### Debugging backend plugin
+
+For debugging backend part written on Go, you should go through a few steps. First, build a plugin with special flags for debugging:
+
+```sh
+make build-debug
+```
+
+Then, configure your editor to connect to [delve](https://github.com/go-delve/delve) debugger running in headless mode. This is an example for VS Code:
+```json
+{
+  "version": "0.2.0",
+  "configurations": [
+    {
+      "name": "Debug backend plugin",
+      "type": "go",
+      "request": "attach",
+      "mode": "remote",
+      "port": 3222,
+      "host": "127.0.0.1",
+    },
+  ]
+}
+```
+
+Finally, run grafana-server and then execute `./debug-backend.sh` from grafana-zabbix root folder. This script will attach delve to running plugin. Now you can go to the VS Code and run _Debug backend plugin_ debug config.
