 2. Run `bin/dev`
 
+## Linting & Formatting
+
+#### Ruby
+
+We use [Standard Ruby](https://github.com/standardrb/standard) for linting and formatting.
+- Run `bundle exec rubocop` to check all ruby files
+- Run `bundle exec rubocop -a` to auto-correct offenses
+- [How do I run RuboCop in my editor?](https://docs.rubocop.org/rubocop/1.25/integration_with_other_tools.html#editor-integration)
+
+#### ERB
+
+We use [ERB Lint](https://github.com/Shopify/erb-lint) to lint our ERB files.
+- Run `bundle exec erblint --lint-all` to check all ERB files
+- Run `bundle exec erblint --lint-all -a` to auto-correct offenses. WARNING: This command isn't safe and can break your code.
+
+#### JavaScript
+
+We use [StandardJS](https://standardjs.com/) to lint our JavaScript files.
+- Install by running `npm install standard --global`
+- Run `standard` to check all JavaScript files
+- Run `standard --fix` to auto-correct offenses
+- [How do I run StandardJS in my editor?](https://standardjs.com/#are-there-text-editor-plugins)
+- [How do I make the output more readable?](https://github.com/standard/standard?tab=readme-ov-file#how-do-i-make-the-output-all-colorful-and-pretty)
+
+#### Spelling
+
+We use [Typos](https://github.com/crate-ci/typos) as a spell checker.
+- Install by running `brew install typos-cli`
+- Run `typos` to check all files
+- Run `typos -w` to auto-correct offenses
+- For false positives and other configuration, see the `_typos.yml` file
+
 ## Testing
 
 Run tests by using `bundle exec rspec`.
