-These docs will give you a quick overview of the project and all of its pieces, as well as provide guides to help you get set up.
+## Quickstart
 
-The docs are broken down into the following categories:
+These steps will get you running ESLint with our recommended rules on your TypeScript code as quickly as possible.
 
-- [I want to lint my TypeScript codebase.](./linting/README.md)
+### Step 1: Installation
 
-- [I want to develop an ESLint plugin in TypeScript.](./development/CUSTOM_RULES.md)
+First, install the required packages for [ESLint](https://eslint.io), [TypeScript](https://typescriptlang.org), and this plugin:
+
+```bash npm2yarn
+npm install --save-dev @typescript-eslint/parser @typescript-eslint/eslint-plugin eslint typescript
+```
+
+### Step 2: Configuration
+
+Next, create a `.eslintrc.cjs` config file in the root of your project, and populate it with the following:
+
+```js title=".eslintrc.cjs"
+module.exports = {
+  extends: ['eslint:recommended', 'plugin:@typescript-eslint/recommended'],
+  parser: '@typescript-eslint/parser',
+  plugins: ['@typescript-eslint'],
+  root: true,
+};
+```
+
+:::info
+If your project doesn't use ESM, naming the file as `.eslintrc.js` is fine. See [ESLint's Configuration Files docs](https://eslint.org/docs/user-guide/configuring/configuration-files) for more info.
+:::
+
+### Step 3: Running ESLint
+
+Open a terminal to the root of your project and run the following command:
+
+<Tabs groupId="npm2yarn">
+<TabItem value="npm">
+
+```bash
+npx eslint .
+```
+
+</TabItem>
+<TabItem value="Yarn">
+
+```bash
+yarn eslint .
+```
+
+</TabItem>
+</Tabs>
+
+ESLint will lint all TypeScript compatible files within the current folder, and will output the results to your terminal.
+
+## Details
+
+- You can read more about configuring ESLint [in their documentation on configuration](https://eslint.org/docs/user-guide/configuring).
+- You can read more about the rules provided by ESLint [in their documentation on their rules](https://eslint.org/docs/rules/).
+- You can read more about the rules provided by typescript-eslint in [our rules documentation](/rules).
+
+### Configuration Values
+
+- `parser: '@typescript-eslint/parser'` tells ESLint to use the [`@typescript-eslint/parser`](https://github.com/typescript-eslint/typescript-eslint/tree/main/packages/parser) package you installed to parse your source files.
+  - This is required, or else ESLint will throw errors as it tries to parse TypeScript code as if it were regular JavaScript.
+- `plugins: ['@typescript-eslint']` tells ESLint to load the [`@typescript-eslint/eslint-plugin`](https://github.com/typescript-eslint/typescript-eslint/tree/main/packages/eslint-plugin)) package as a plugin.
+  - This allows you to use typescript-eslint's rules within your codebase.
+- `extends: [ ... ]` tells ESLint that your config extends the given configurations.
+  - `eslint:recommended` is ESLint's inbuilt "recommended" config - it turns on a small, sensible set of rules which lint for well-known best-practices.
+  - `plugin:@typescript-eslint/recommended` is our "recommended" config - it's just like `eslint:recommended`, except it only turns on rules from our TypeScript-specific plugin.
+
+## Next Steps
+
+We provide a plethora of powerful rules that utilize the power of TypeScript's type information. [Visit the next page for a setup guide](./linting/TYPED_LINTING.md 'Visit the next page for a typed rules setup guide').
+
+If you're having problems getting this working, please have a look at our [Troubleshooting & FAQs](./linting/TROUBLESHOOTING.md).

+[ESLint shareable configurations](https://eslint.org/docs/latest/developer-guide/shareable-configs) exist to provide a comprehensive base config for you, with the intention that you add the config and it gives you an opinionated setup.

 ## Built-In Configurations
 
 `@typescript-eslint/eslint-plugin` includes built-in configurations you can extend from to pull in the recommended starting rules.
 
 With the exception of `strict`, all configurations are considered "stable".
 Rule additions and removals are treated as breaking changes and will only be done in major version bumps.

+We recommend most packages extend from [`recommended-requiring-type-checking`](#recommended-requiring-type-checking) (which requires [typed linting](./TYPED_LINTING.md)).

+## Prettier
+
+If you use [`prettier`](https://www.npmjs.com/package/prettier), there is also a helpful config to help ensure ESLint doesn't report on formatting issues that prettier will fix: [`eslint-config-prettier`](https://www.npmjs.com/package/eslint-config-prettier).
