+  # This configuration file is used with different version of golangci-lint to avoid regressions:
+  # the linters can change between version,
+  # their configuration may be not compatible or their reports can be different,
+  # and this can break some of our tests.
+  # Also, some linters are not relevant for the project (ex: linters related to SQL).
