-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
-
-## Available Scripts
-
-In the project directory, you can run:
-
-### `yarn start`
-
-Runs the app in the development mode.<br />
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
-
-The page will reload if you make edits.<br />
-You will also see any lint errors in the console.
-
-### `yarn test`
-
-Launches the test runner in the interactive watch mode.<br />
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
-
-### `yarn build`
-
-Builds the app for production to the `build` folder.<br />
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.<br />
-Your app is ready to be deployed!
-
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
-
-### `yarn eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
-
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
-
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

+## Coderan: Validator
+The smart React element validator
+
+### Introduction
+The goal of this package, is to simplify the struggle of validating elements in React, with a simple system which allows
+users to add their own rules.  
+The system communicates directly with the elements in the DOM, and is therefore widely compatible with other libraries,
+like [Bootstrap](https://react-bootstrap.github.io/).
+
+### The concept
+Validator consists of two main elements, an `Area` and a `Provider`. Areas are a sort of wrappers having elements that
+need validation as their children. An area scans the underlying components and elements and indexes validatable elements.
+
+Providers on the other hand are wrappers around areas, and allow them to communicate between each other. This communication
+is needed in order to match with values in other areas. It can also be used to validate all areas at once, and preventing
+actions to happen while not all areas are valid. 
+
+### How to use
+First, start with adding rules to the validator in order to use them. There are some rules pre-made, but more specific
+rules you have to create yourself.
+
+```javascript
+import { Validator } from '@coderan/validator';
+import { min } from '@coderan/rules/min';
+
+Validator.extend('min', min);
+```
+
+#### Area
+Basic usage:
+```jsx
+import { ValidatorArea } from '@coderan/validator';
+
+<ValidatorArea rules="required">
+    <input name="username" />
+</ValidatorArea>
+```
+When the input is focused and blurred, the `required` rule is called.
+
+Every area needs a name. This name is used to index areas in the provider, and make meaningful error messages. When using
+multiple inputs within an area, i.e. when validating a multi-input date of birth, `name` prop is required when defining
+the `ValidatorArea` component. Like so:
+
+```jsx
+import { ValidatorArea } from '@coderan/validator';
+
+<ValidatorArea rules="min" name="dob">
+    <input name="day" />
+    <input name="month" />
+    <input name="year" />
+</ValidatorArea>
+```
+
+Showing errors:
+```jsx
+import { ValidatorArea } from '@coderan/validator';
+
+<ValidatorArea rules="min" name="dob">
+    {({ errors }) => (
+        <>
+            <input name="username" />
+            { errors.length && <span>{errors[0]}</span> }
+        </>
+    )}
+</ValidatorArea>
+```
+
+#### Provider
+Basic usage:
+```jsx
+import { ValidatorProvider, ValidatorArea } from '@coderan/validator';
+
+<ValidatorProvider>
+    {({ validate }) => (
+        <>
+            <ValidatorArea rules="min" name="dob">
+                <input name="day" />
+                <input name="month" />
+                <input name="year" />
+            </ValidatorArea>
+            <ValidatorArea rules="min" name="dob">
+                <input name="day" />
+                <input name="month" />
+                <input name="year" />
+            </ValidatorArea>
+            <button
+                onClick={() => validate(() => alert('valid'))}>Check</button>
+        </>
+    )}
+</ValidatorProvider>
+```
+
+It is possible to give the validator a `rules` prop as well, whose rules apply to all underlying areas:
+
+```jsx
+import { ValidatorProvider, ValidatorArea } from '@coderan/validator';
+
+<ValidatorProvider rules="required">
+    <ValidatorArea rules="min:5">
+        {/* on blur, both required and min rules are applied */}
+        <input name="username" /> 
+    </ValidatorArea>
+</ValidatorProvider>
+```
+
+#### Adding rules
+
+With access to validator
+```javascript
+import { Validator } from '@coderan/validator'
+Validator.extend('test_types', (validator: Validator) => ({
+    passed(): boolean {
+        return validator.refs(undefined, HTMLInputElement).length === 1
+            && validator.refs('test1', HTMLTextAreaElement).length === 1
+            && validator.refs('test1').length === 1
+            && validator.refs('test1', HTMLProgressElement).length === 0;
+    },
+    message(): string {
+        return 'test';
+    }
+}));
+```
+
+or without
+```javascript
+import { getValue, isInputElement, isSelectElement } from '@/utils/dom';
+
+export default {
+    passed(elements: HTMLElement[]): boolean {
+        return elements.every((element: HTMLElement) => {
+            if (isInputElement(element) || isSelectElement(element)) {
+                const value = getValue(element);
+
+                return value && value.length;
+            }
+
+            return true;
+        })
+    },
+
+    message(): string {
+        return `{name} is required`;
+    }
+};
+```
+
+You can create your own rules, as long as it follows this interface:
+```typescript
+import { Validator } from '@coderan/validator';
+
+/**
+ * Function to access validator using the rule
+ */
+declare type RuleFunction = (validator: Validator) => RuleObject;
+
+/**
+ * Object structure rules must implement
+ */
+declare type RuleObject = {
+    /**
+     * Returns whether the rule passed with the given element(s)
+     */
+    passed(elements: HTMLElement[], ...args: string[]): boolean;
+    /**
+     * Message shown when the rule doesn't pass
+     */
+    message(): string;
+}
+
+export type Rule = RuleObject | RuleFunction;
+```
+
+### Happy Coding!
