+# Invalid Token Value
+
+#### Why This Error Occurred
+
+The `--token` flag was specified, but its contents are invalid.
+
+#### Possible Ways to Fix It
+
+The `--token` flag must only contain numbers (0-9) and letters from the alphabet (a-z and A-Z). This needs to be the token of the user account as which you'd like to act.
+
+You can either get the token from the `./now/auth.json` file located in your user directory or [from the dashboard](https://zeit.co/account/tokens).

+/**
+ * `DetectorFilesystem` is an abstract class that represents a virtual filesystem
+ * to perform read-only operations on in order to detect which framework is being
+ * used.
+ *
+ * Its abstract methods must be implemented by a subclass that perform the actual
+ * FS operations. Example subclasses could be implemented as:
+ *
+ *  - Local filesystem, which proxies the FS operations to the equivalent `fs`
+ *    module functions.
+ *  - HTTP filesystem, which implements the FS operations over an HTTP server
+ *    and does not require a local copy of the files.
+ *  - `Files` filesystem, which operates on a virtual `Files` object (i.e. from
+ *    the `glob()` function) which could include `FileFsRef`, `FileBlob`, etc.
+ *
+ * This base class implements various helper functions for common tasks (i.e.
+ * read and parse a JSON file). It also includes caching for all FS operations
+ * so that multiple detector functions de-dup read operations on the same file
+ * to reduce network/filesystem overhead.
+ *
+ * **NOTE:** It's important that all instance methods in this base class are
+ * bound to `this` so that the `fs` object may be destructured in the detector
+ * functions. The easiest way to do this is to use the `=` syntax when defining
+ * methods in this class definition.

+# Angular
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 8.3.17.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).

+# Brunch + Babel/ES6
+
+This is a modern JS skeleton for [Brunch](http://brunch.io).
+
+## Installation
+
+Clone this repo manually or use `brunch new dir -s es6`
+
+## Getting started
+
+- Install (if you don't have them):
+  - [Node.js](http://nodejs.org): `brew install node` on OS X
+  - [Brunch](http://brunch.io): `npm install -g brunch`
+  - Brunch plugins and app dependencies: `npm install`
+- Run:
+  - `npm start` — watches the project with continuous rebuild. This will also launch HTTP server with [pushState](https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Manipulating_the_browser_history).
+  - `npm run build` — builds minified project for production
+- Learn:
+  - `public/` dir is fully auto-generated and served by HTTP server. Write your code in `app/` dir.
+  - Place static files you want to be copied from `app/assets/` to `public/`.
+  - [Brunch site](http://brunch.io), [Getting started guide](https://github.com/brunch/brunch-guide#readme)
+
+## ES-next
+
+To use proposed JS features not included into ES6, do this:
+
+- `npm install --save-dev babel-preset-stage-0`
+- in `brunch-config.js`, add the preset: `presets: ['latest', 'stage-0']`

+  Gatsby's default starter
+</h1>
+
+Kick off your project with this default boilerplate. This starter ships with the main Gatsby configuration files you might need to get up and running blazing fast with the blazing fast app generator for React.
+
+_Have another more specific idea? You may want to check out our vibrant collection of [official and community-created starters](https://www.gatsbyjs.org/docs/gatsby-starters/)._
+
+## 🚀 Quick start
+
+1.  **Create a Gatsby site.**
+
+    Use the Gatsby CLI to create a new site, specifying the default starter.
+
+    ```shell
+    # create a new Gatsby site using the default starter
+    gatsby new my-default-starter https://github.com/gatsbyjs/gatsby-starter-default
+    ```
+
+1.  **Start developing.**
+
+    Navigate into your new site’s directory and start it up.
+
+    ```shell
+    cd my-default-starter/
+    gatsby develop
+    ```
+
+1.  **Open the source code and start editing!**
+
+    Your site is now running at `http://localhost:8000`!
+
+    _Note: You'll also see a second link: _`http://localhost:8000/___graphql`_. This is a tool you can use to experiment with querying your data. Learn more about using this tool in the [Gatsby tutorial](https://www.gatsbyjs.org/tutorial/part-five/#introducing-graphiql)._
+
+    Open the `my-default-starter` directory in your code editor of choice and edit `src/pages/index.js`. Save your changes and the browser will update in real time!
+
+## 🧐 What's inside?
+
+A quick look at the top-level files and directories you'll see in a Gatsby project.
+
+    .
+    ├── node_modules
+    ├── src
+    ├── .gitignore
+    ├── .prettierrc
+    ├── gatsby-browser.js
+    ├── gatsby-config.js
+    ├── gatsby-node.js
+    ├── gatsby-ssr.js
+    ├── LICENSE
+    ├── package-lock.json
+    ├── package.json
+    └── README.md
+
+1.  **`/node_modules`**: This directory contains all of the modules of code that your project depends on (npm packages) are automatically installed.
+
+2.  **`/src`**: This directory will contain all of the code related to what you will see on the front-end of your site (what you see in the browser) such as your site header or a page template. `src` is a convention for “source code”.
+
+3.  **`.gitignore`**: This file tells git which files it should not track / not maintain a version history for.
+
+4.  **`.prettierrc`**: This is a configuration file for [Prettier](https://prettier.io/). Prettier is a tool to help keep the formatting of your code consistent.
+
+5.  **`gatsby-browser.js`**: This file is where Gatsby expects to find any usage of the [Gatsby browser APIs](https://www.gatsbyjs.org/docs/browser-apis/) (if any). These allow customization/extension of default Gatsby settings affecting the browser.
+
+6.  **`gatsby-config.js`**: This is the main configuration file for a Gatsby site. This is where you can specify information about your site (metadata) like the site title and description, which Gatsby plugins you’d like to include, etc. (Check out the [config docs](https://www.gatsbyjs.org/docs/gatsby-config/) for more detail).
+
+7.  **`gatsby-node.js`**: This file is where Gatsby expects to find any usage of the [Gatsby Node APIs](https://www.gatsbyjs.org/docs/node-apis/) (if any). These allow customization/extension of default Gatsby settings affecting pieces of the site build process.
+
+8.  **`gatsby-ssr.js`**: This file is where Gatsby expects to find any usage of the [Gatsby server-side rendering APIs](https://www.gatsbyjs.org/docs/ssr-apis/) (if any). These allow customization of default Gatsby settings affecting server-side rendering.
+
+9.  **`LICENSE`**: Gatsby is licensed under the MIT license.
+
+10. **`package-lock.json`** (See `package.json` below, first). This is an automatically generated file based on the exact versions of your npm dependencies that were installed for your project. **(You won’t change this file directly).**
+
+11. **`package.json`**: A manifest file for Node.js projects, which includes things like metadata (the project’s name, author, etc). This manifest is how npm knows which packages to install for your project.
+
+12. **`README.md`**: A text file containing useful reference information about your project.
+
+## 🎓 Learning Gatsby
+
+Looking for more guidance? Full documentation for Gatsby lives [on the website](https://www.gatsbyjs.org/). Here are some places to start:
+
+- **For most developers, we recommend starting with our [in-depth tutorial for creating a site with Gatsby](https://www.gatsbyjs.org/tutorial/).** It starts with zero assumptions about your level of ability and walks through every step of the process.
+
+- **To dive straight into code samples, head [to our documentation](https://www.gatsbyjs.org/docs/).** In particular, check out the _Guides_, _API Reference_, and _Advanced Tutorials_ sections in the sidebar.
