+#### Important
+
+`ruleguard` (a "rule" inside `gocritic`) is disabled, only with go1.21, due to a bug of `ruleguard`
+
+The Go version should be 1.21 inside `go.mod` or be defined inside the `run` section:
+
+<details><summary>go.mod</summary>
+
+```go
+module your/module/name
+
+go 1.21
+
+// ...
+
+```
+
+</details>
+
+<details><summary>.golangci.yml</summary>
+
+```yml
+run:
+    go: '1.21'
+```
+
+</details>
+
+<details><summary>CLI flags</summary>
+
+```bash
+--go=1.21
