-# Git hooks
-
-Installation:
-
-```
-git config core.hooksPath contrib/githooks
-```
-
-## pre-commit
-
-The hook automatically runs `gofmt`, `goimports`, and `misspell`
-to correctly format the `.go` files included in the commit, provided
-that all the aforementioned commands are installed and available
-in the user's search `$PATH` environment variable:
-
-```
-go install golang.org/x/tools/cmd/goimports
-go install github.com/golangci/misspell/cmd/misspell@master
-```
-
-It also runs `go mod tidy` and `golangci-lint` if available.
