 This is GitHub project template for a Go library. It has been created for ease-of-use for anyone who wants to:

+## FAQ
+
+### Why Mage instead of Make
+
+Here is [why](https://github.com/magefile/mage#why).
+However, updating to Make is pretty straightforward.
+
+1. Replace [magefile.go](magefile.go) with a `Makefile` file:
+
+```make
+.DEFAULT_GOAL := help
+
+.PHONY: all
+all: ## full build: build, lint, test
+all: build lint test
+
+.PHONY: build
+build: ## go build
+	go build ./...
+
+.PHONY: lint
+lint: ## golangci-lint
+	golangci-lint run
+
+.PHONY: test
+test: ## go test with race detector and code covarage
+	go test -race -covermode=atomic
+
+.PHONY: help
+help:
+	@grep -E '^[a-zA-Z_-]+:.*?## .*$$' $(MAKEFILE_LIST) | sort | awk 'BEGIN {FS = ":.*?## "}; {printf "\033[36m%-30s\033[0m %s\n", $$1, $$2}'
+```
+
+2. Remove Mage installation from [Dockerfile](Dockerfile).
+1. Update [docker-compose.yml](docker-compose.yml) and [.vscode/tasks.json](.vscode/tasks.json) to use `make`.
+
+If you want to use Make on bare-metal Windows, then you can use [WSL (Windows Subsystem for Linux)](https://docs.microsoft.com/en-us/windows/wsl/install-win10) or install [Make Windows port to Git Bash](https://gist.github.com/evanwill/0207876c3243bbb6863e65ec5dc3f058).
+
+### Why nothing for GoLand
+
+The maintainer does not use GoLand. Fell free to create a pull request for [#2](https://github.com/golang-templates/library/issues/2).
+
+### Why GitHub Actions, not any other CI server
+
+GitHub Actions is out-of-the-box if you are already using GitHub.
+However, changing to any other CI server should be very simple, because this repository uses Docker Compose to run CI build to make the transition easy.
+
+For [CircleCI](https://circleci.com/docs/2.0/executor-types/#using-machine) create `.circleci/config.yml` file:
+
+```yml
+version: 2.1
+jobs:
+  build:
+    machine:
+      image: ubuntu-1604:201903-01
+    steps:
+      - checkout
+      - run: docker-compose up --abort-on-container-exit
+```
