+## Entrypoints
+
+This repository adheres to the
+[Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
+standard: normalized scripts in `script/` are the entrypoints for the
+development workflow, and the Makefile targets are thin shims that call them.
+The scripts are POSIX sh (not bash) so they run in minimal containers such as
+alpine. We provide:
+
+- `script/bootstrap` — install all dependencies (go and golangci-lint if
+  missing, then `go mod download`)
+- `script/setup` — set up the repo for development after a fresh clone: runs
+  `script/bootstrap`, then `script/install-precommit`
+- `script/projectname` — output the project name (our own extension); used by
+  `script/docker` for the image tag
+- `script/test` — run the test suite (`go test -v ./...`)
+- `script/lint` — run golangci-lint
+- `script/fmt` — format all files (goimports plus `golangci-lint run --fix`;
+  writes)
+- `script/fmt-check` — check formatting (read-only); fails if `gofmt -l`
+  reports files
+- `script/check` — run all checks: `test`, `lint`, `fmt-check` (our own
+  extension)
+- `script/docker` — build the Docker image, tagged via `script/projectname`
+  (byte-identical across repos)
+- `script/cibuild` — cd to the repo root and `docker build .` (what CI runs;
+  the image build runs the checks)
+- `script/precommit` — run by the git pre-commit hook (our own extension);
+  runs a `go mod tidy` guard, then `script/check`
+- `script/install-precommit` — installs the git pre-commit hook (our own
+  extension); `make hooks` shims to it
+
+`make hooks` installs the pre-commit hook that runs `script/precommit`.
