+
+## Features
+
+- Responsive grid layout with zero media queries
+- Simple API for handling tiled layouts
+- Customizable column width and gutters
+
+
+## Props
+
+### `width` (number or string)
+
+Sets the width at which child elements will break into columns.
+Pass a number for pixel values or a string for any other valid CSS length.
+
 ```jsx
-// Higher order component
-import React from 'react'
-import { createGrid } from 'react-css-grid'
+<Grid width={512} />
+```
+
+### `gap` (number or string)
 
-const CustomGrid = (props) => <div {...props} />
+Sets the gutter (`grid-gap`) between columns.
+Pass a number for pixel values or a string for any other valid CSS length.
 
-export default createGrid(CustomGrid)
+```jsx
+<Grid gap={16} />
 ```
 
-## Features
-- Simple, encapsulated grid layout API
-- Uses CSS for native @media-rule-based responsive styles
-- Works with server-side rendering
-
-## Grid component props
-- `col` (number 0–12) sets width across all breakpoints based on a 12 column grid.
-- `sm` (number 0–12) sets width from the `sm` breakpoint up
-- `md` (number 0–12) sets width from the `md` breakpoint up
-- `lg` (number 0–12) sets width from the `lg` breakpoint up
-- `align` (string, `top`, `middle`, `bottom`, or `baseline`) - sets vertical align
-
-## How it works
-
-The Grid component uses `display: inline-block` to create grid layouts.
-It creates CSS rules based on props and inserts that string into an inline style tag.
-The component only creates the rules it needs for itself,
-however other Grid components may generate duplicative styles of their own.
-
-## Caveats
-- Produces an inline style **tag** within the body (e.g. not inline styles)
-- Similar component instances create duplicative CSS rules – this may or may not affect performance
-- Atomic class selectors are global
