+### How to Fmt & Lint Automatically
+
+Here are some useful scripts to have in your `package.json`, and a sample file
+to run them with GitHub Actions (Workflows):
+
+```sh
+npm run
+        fmt
+        lint
+        bump <major|minor|patch|prerelease>
+        prepublish # also runs after npm install
+```
+
+```sh
+# bump
+npm pkg set scripts.bump='npm version -m "chore(release): bump to v%s"'
+
+# fmt
+npm pkg set scripts.fmt='npm run fixjson && npm run prettier'
+npm pkg set scripts.prettier="npx -p prettier@2 -- prettier --write '**/*.{md,js,jsx,json,css,html,vue}'"
+npm pkg set scripts.fixjson="npx -p fixjson@1 -- fixjson -i 2 -w '*.json' '*/*.json'"
+echo 'node_modules' >> .prettierignore
+
+# lint
+npm pkg set scripts.lint='npm run jshint'
+npm pkg set scripts.jshint="npx -p jshint@2 -- jshint -c ./.jshintrc ./*.js ./*/*.json"
+echo 'node_modules' >> .jshintignore
+
+# prepublish
+npm pkg set scripts.prepublish='npm run lint && npm run fmt'
+```
