-
-*currency.js* is a lightweight ~1kb javascript library for working with currency values. It was built to work around floating point issues in javascript. This [talk by Bartek Szopka](http://www.youtube.com/watch?v=MqHDDtVYJRI) explains in detail why javascript has floating point issues.
-
-currency.js works with values as integers behind the scenes, resolving some of the most basic precision problems.
-
-```javascript
-2.51 + .01;                   // 2.5199999999999996
-currency(2.51).add(.01);      // 2.52
-
-2.52 - .01;                   // 2.5100000000000002
-currency(2.52).subtract(.01); // 2.51
-```
-
-This should work for most *reasonable* values of currencies. As long as your currency values are less than 2<sup>53</sup> (in cents) or 90,071,992,547,409.91 you should be okay.
-
-### Features
-
-* *0 dependencies!*
-* Immutable
-* Flexible formatting options
-* Handles *any* type of currency input, strings, numbers, or another currency instance
-
-### Installation
-
-With [npm](https://www.npmjs.com/):
-
-```sh
-npm install --save currency.js
-```
-
-With [yarn](https://yarnpkg.com):
-
-```sh
-yarn add currency.js
-```
-
-Via cdn:
-
-```html
-<script src="https://unpkg.com/currency.js@~2.0.0/dist/currency.min.js"></script>
-```
-
-Need the latest cutting edge? All commits on master are tagged with `next` on npm:
-
-```sh
-npm install --save currency.js@next
-```
-
-### Usage
-
-Currency will accept numbers, strings, or the currency object itself as values.
-
-```javascript
-currency(123);      // 123.00
-currency(1.23);     // 1.23
-currency("1.23")    // 1.23
-currency("$12.30")  // 12.30
-
-var value = currency("123.45");
-currency(value);    // 123.45
-```
-
-Currency accepts decimal values (i.e. `1.23`) with a default precision of 2, but can accept a minor currency unit (e.g. cents in a dollar). This will respect the precision option when parsing.
-
-```javascript
-currency(123, { fromCents: true });               // 1.23
-currency('123', { fromCents: true });             // 1.23
-currency(123, { fromCents: true, precision: 0 }); // 123
-currency(123, { fromCents: true, precision: 3 }); // 0.123
-```
-
-There's various arithmetic methods that help take the guesswork out of trying to resolve floating point problems.
-
-```javascript
-currency(123.50).add(0.23);       // 123.73
-currency(5.00).subtract(0.50);    // 4.50
-currency(45.25).multiply(3);      // 135.75
-currency(1.12).distribute(5);     // [0.23, 0.23, 0.22, 0.22, 0.22]
-```
-
-There's even a built in formatter that will automatically place comma delimiters in the right place.
-
-```javascript
-currency("2,573,693.75").add("100,275.50").format();  // "$2,673,969.25"
-currency("1,237.72").subtract(300).format();          // "$937.72"
-```
-
-You can also change the format, localizing the decimal and/or delimiter to your locale.
-
-```javascript
-var euro = value => currency(value, { symbol: "€", separator: ".", decimal: "," });
-euro("2.573.693,75").add("100.275,50").format();  // "€2.673.969,25"
-euro("1.237,72").subtract(300).format();          // "€937,72"
-```
-
-### Options
-
-*currency.js* comes with its own set of default options conforming to USD. You can customize these according to your locale.
-
-`symbol` *default*: `$`<br/>
-Currency symbol included when calling `currency.format()`.
-
-`separator` *default*: `,`<br/>
-Separator dividing the number groups when calling `currency.format()`.
-
-`decimal` *default*: `.`<br/>
-Decimal used when calling `currency.format()`.
-
-`precision` *default*: `2`<br/>
-Number of decimal places to store as cents.
-
-`pattern` *default*: `!#`<br/>
-Allows you to customize the format pattern using `!` as replacement for the currency symbol and `#` as replacement for the currency amount.
-
-`negativePattern` *default*: `-!#`<br/>
-Allows you to customize the negative format pattern using `!` as replacement for the currency symbol and `#` as replacement for the currency amount.
-
-`format` *default* `null`
-Allows you to customize the format of the currency when calling `currency.format()`. `format` passes in the `currency` object as well as the `options` object to the function and expects a string to be returned. Use this when the provided formatting options do not meet your needs.
-
-`errorOnInvalid` *default*: `false`<br/>
-If an invalid value such as `null` or `undefined` is passed in, will throw an error.
-
-`increment` *default*: `null`<br/>
-When implementing a currency that implements rounding, setting the increment value will allow you to set the closest increment to round the display value to. `currency(1.48, { increment: .05 }); // => 1.50`
-
-`useVedic` *default*: `false`<br/>
-Formats number groupings using the Indian Numbering System, i.e. `10,00,000.00`
-
-`fromCents` *default*: `false`<br/>
-Parse the amount value as a minor currency unit (e.g. cents in a dollar) instead of dollars.

-
-### Internationalization Examples
-
-```js
-currency(1.23, { separator: " ", decimal: ",", symbol: "€" });
-```
-
-If you need to work with multiple currency values, the easiest way is to setup factory functions with your required currency settings.
-
-```js
-const USD = value => currency(value, { symbol: "$", precision: 2 });
-const JPY = value => currency(value, { symbol: "¥", precision: 0 });
-const GAS = value => currency(value, { precision: 3 });
-
-USD(1234.56).format(); // "$1,234.56"
-JPY(1234.56).format(); // "¥1,235"
-GAS(1234.56).format(); // "$1,234.560"
-```
-
-## Add-ons
-
-* [babel-plugin-transform-currency-operators](https://github.com/scurker/babel-plugin-transform-currency-operators): An experimental babel plugin for transforming currency operations `currency(1.23) + 4.56` to `currency(1.23).add(4.56)`.
-
-## Other Libraries
-
-Maybe currency.js isn't the right fit for your needs. Check out some of these other fine libraries:
-
-* [accounting.js](https://github.com/openexchangerates/accounting.js)
-* [dinero.js](https://github.com/sarahdayan/dinero.js)
-* [walletjs](https://github.com/dleitee/walletjs)
