+----------
+### golangci-lint-v2
+A FAST linter aggregator using golangci-lint v2 architecture, with enhanced colored output, fewer false-positives, and support for v2 yaml/toml configuration files.
+
+ - Uses golangci-lint v2 architecture (supports `version: "2"` in config files)
+ - Manages multiple linters with improved performance
+ - Can replace many/most other hooks
+ - Can report only new issues (see `--new`)
+ - Can modify files (see `--fix`)
+ - Includes built-in formatting command (`fmt`)
+
+| Hook ID                      | Description                                                                                  |

+
+##### Install
+```
+go install github.com/golangci/golangci-lint/cmd/golangci-lint-v2@latest
+```
+
+##### Configuration
+The v2 hooks require a configuration file with `version: "2"` declared:
+```yaml
+# .golangci.yaml
+version: "2"
+
+linters:
+  default: all  # Enable all linters by default
+  settings:
+    staticcheck:
+      checks: ["all"]
+formatters:
+  enable:
+    - goimports
+    - gofumpt
+issues:
+  fix: true
+```
+
+##### Useful Args
+```
+   --config PATH     : Specify config file (supports v2 format)
+   --disable linters : Disable specific linter(s)
+   --enable-all      : Enable ALL linters
+   --enable linters  : Enable specific linter(s)
+   --fast            : Run only fast linters (from enabled linters sets)
+   --fix             : Fix found issues (if supported by linter)
+   --new             : Show only new issues (see help for further details)
+   --no-config       : don't read config file
+   --presets presets : Enable presets of linters
+```
+
+##### Help

+ - `golangci-lint-v2 run -h`
+ - `golangci-lint-v2 fmt -h`
