+
+
+## Usage
+
+```js
+const ora = require('ora');
+
+const spinner = ora('Loading unicorns').start();
+
+setTimeout(() => {
+	spinner.color = 'yellow';
+	spinner.text = 'Loading rainbows';
+}, 1000);
+```
+
+
+## API
+
+### ora([options|text])
+
+If a string is provided, it is treated as a shortcut for [`options.text`](#text).
+
+#### options
+
+Type: `Object`
+
+##### text
+
+Type: `string`
+
+Text to display after the spinner.
+
+##### prefixText
+
+Type: `string`
+
+Text to display before the spinner.
+
+##### spinner
+
+Type: `string` `Object`<br>
+Default: `dots` <img src="screenshot-spinner.gif" width="14">
+
+Name of one of the [provided spinners](https://github.com/sindresorhus/cli-spinners/blob/master/spinners.json). See `example.js` in this repo if you want to test out different spinners. On Windows, it will always use the `line` spinner as the Windows command-line doesn't have proper Unicode support.
+
+Or an object like:
+
+```js
+{
+	interval: 80, // Optional
+	frames: ['-', '+', '-']
+}
+```
+
+##### color
+
+Type: `string`<br>
+Default: `cyan`<br>
+Values: `black` `red` `green` `yellow` `blue` `magenta` `cyan` `white` `gray`
+
+Color of the spinner.
+
+##### hideCursor
+
+Type: `boolean`<br>
+Default: `true`
+
+Set to `false` to stop Ora from hiding the cursor.
+
+##### indent
+
+Type: `number`<br>
+Default: `0`
+
+Indent the spinner with the given number of spaces.
+
+##### interval
+
+Type: `number`<br>
+Default: Provided by the spinner or `100`
+
+Interval between each frame.
+
+Spinners provide their own recommended interval, so you don't really need to specify this.
+
+##### stream
+
+Type: `stream.Writable`<br>
+Default: `process.stderr`
+
+Stream to write the output.
+
+You could for example set this to `process.stdout` instead.
+
+##### isEnabled
+
+Type: `boolean`
+
+Force enable/disable the spinner. If not specified, the spinner will be enabled if the `stream` is being run inside a TTY context (not spawned or piped) and/or not in a CI environment.
+
+Note that `{isEnabled: false}` doesn't mean it won't output anything. It just means it won't output the spinner, colors, and other ansi escape codes. It will still log text.
+
