+# TSDX React User Guide
+
+Congrats! You just saved yourself hours of work by bootstrapping this project with TSDX. Let’s get you oriented with what’s here and how to use it.
+
+> This TSDX setup is meant for developing React components (not apps!) that can be published to NPM. If you’re looking to build an app, you should use `create-react-app`, `razzle`, `nextjs`, `gatsby`, or `react-static`.
+
+> If you’re new to TypeScript and React, checkout [this handy cheatsheet](https://github.com/sw-yx/react-typescript-cheatsheet/)
+
+## Commands
+
+TSDX scaffolds your new library inside `/src`, and also sets up a [Parcel-based](https://parceljs.org) playground for it inside `/example`.
+
+The recommended workflow is to run TSDX in one terminal:
+
+```bash
+npm start # or yarn start
+```
+
+This builds to `/dist` and runs the project in watch mode so any edits you save inside `src` causes a rebuild to `/dist`.
+
+Then run the example inside another:
+
+```bash
+cd example
+npm i # or yarn to install dependencies
+npm start # or yarn start
+```
+
+The default example imports and live reloads whatever is in `/dist`, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above. **No symlinking required**, [we use Parcel's aliasing](https://github.com/palmerhq/tsdx/pull/88/files).
+
+To do a one-off build, use `npm run build` or `yarn build`.
+
+To run tests, use `npm test` or `yarn test`.
+
+## Configuration
+
+Code quality is [set up for you](https://github.com/palmerhq/tsdx/pull/45/files) with `prettier`, `husky`, and `lint-staged`. Adjust the respective fields in `package.json` accordingly.
+
+### Jest
+
+Jest tests are set up to run with `npm test` or `yarn test`. This runs the test watcher (Jest) in an interactive mode. By default, runs tests related to files changed since the last commit.
+
+#### Setup Files
+
+This is the folder structure we set up for you:
+
+```shell
+/example
+  index.html
+  index.tsx       # test your component here in a demo app
+  package.json
+  tsconfig.json
+/src
+  index.tsx       # EDIT THIS
+/test
+  blah.test.tsx   # EDIT THIS
+.gitignore
+package.json
+README.md         # EDIT THIS
+tsconfig.json
+```
+
+#### React Testing Library
+
+We do not set up `react-testing-library` for you yet, we welcome contributions and documentation on this.
+
+### Rollup
+
+TSDX uses [Rollup v1.x](https://rollupjs.org) as a bundler and generates multiple rollup configs for various module formats and build settings. See [Optimizations](#optimizations) for details.
+
+### TypeScript
+
+`tsconfig.json` is set up to interpret `dom` and `esnext` types, as well as `react` for `jsx`. Adjust according to your needs.
+
+## Continuous Integration
+
+### Travis
+
+_to be completed_
+
+### Circle
+
+_to be completed_
+
+## Optimizations
+
+Please see the main `tsdx` [optimizations docs](https://github.com/palmerhq/tsdx#optimizations). In particular, know that you can take advantage of development-only optimizations:
+
+```js
+// ./types/index.d.ts
+declare var __DEV__: boolean;
+
+// inside your code...
+if (__DEV__) {
+  console.log('foo');
+}
+```
+
+You can also choose to install and use [invariant](https://github.com/palmerhq/tsdx#invariant) and [warning](https://github.com/palmerhq/tsdx#warning) functions.
+
+## Module Formats
+
+CJS, ESModules, and UMD module formats are supported.
+
+The appropriate paths are configured in `package.json` and `dist/index.js` accordingly. Please report if any issues are found.
+
+## Using the Playground
+
+```bash
+cd example
+npm i # or yarn to install dependencies
+npm start # or yarn start
+```
+
+The default example imports and live reloads whatever is in `/dist`, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above. **No symlinking required**!
+
+## Deploying the Playground
+
+The Playground is just a simple [Parcel](https://parceljs.org) app, you can deploy it anywhere you would normally deploy that. Here are some guidelines for **manually** deploying with the Netlify CLI (`npm i -g netlify-cli`):
+
+```bash
+cd example # if not already in the example folder
+npm run build # builds to dist
+netlify deploy # deploy the dist folder
+```
+
+Alternatively, if you already have a git repo connected, you can set up continuous deployment with Netlify:
+
+```bash
+netlify init
+# build command: yarn build && cd example && yarn && yarn build
+# directory to deploy: example/dist
+# pick yes for netlify.toml
+```
+
+## Named Exports
+
+Per Palmer Group guidelines, [always use named exports.](https://github.com/palmerhq/typescript#exports) Code split inside your React app instead of your React library.
+
+## Including Styles
+
+There are many ways to ship styles, including with CSS-in-JS. TSDX has no opinion on this, configure how you like.
+
+For vanilla CSS, you can include it at the root directory and add it to the `files` section in your `package.json`, so that it can be imported separately by your users and run through their bundler's loader.
+
+## Publishing to NPM
+
+We recommend using [np](https://github.com/sindresorhus/np).
+
+## Usage with Lerna
+
+When creating a new package with TSDX within a project set up with Lerna, you might encounter a `Cannot resolve dependency` error when trying to run the `example` project. To fix that you will need to make changes to the `package.json` file _inside the `example` directory_.
+
+The problem is that due to the nature of how dependencies are installed in Lerna projects, the aliases in the example project's `package.json` might not point to the right place, as those dependencies might have been installed in the root of your Lerna project.
+
+Change the `alias` to point to where those packages are actually installed. This depends on the directory structure of your Lerna project, so the actual path might be different from the diff below.
+
+```diff
+   "alias": {
+-    "react": "../node_modules/react",
+-    "react-dom": "../node_modules/react-dom"
++    "react": "../../../node_modules/react",
++    "react-dom": "../../../node_modules/react-dom"
+   },
+```
+
+An alternative to fixing this problem would be to remove aliases altogether and define the dependencies referenced as aliases as dev dependencies instead. [However, that might cause other problems.](https://github.com/palmerhq/tsdx/issues/64)
