+
+This is a liquid implementation for both Node.js and browsers. Website: <http://harttle.github.io/liquidjs/>, Live Demo: <https://jsfiddle.net/6u40xbzs/> 
+
+**Features**
+
+* Fully compatible to [shopify][shopify/liquid], with all [tags][tags] and [filters][filters] implemented
+* Support layout(extend) and include syntax
+* In pure JavaScript with Promise-based API
+
+**Differences**
+
+Though being compatible with [Ruby Liquid](https://github.com/shopify/liquid) is one of our priorities, there're still certain differences. You may need some configuration to get it compatible in these senarios:
+
+* Dynamic file locating (enabled by default), which means layout/partial name can be an variable in liquidjs. See [#51](https://github.com/harttle/liquidjs/issues/51).
+* Truthy and Falsy. All values except `undefined`, `null`, `false` are truthy, whereas in Ruby Liquid all except `nil` and `false` are truthy. See [#26](https://github.com/harttle/liquidjs/pull/26).
+* Number Rendering. Since JavaScript do not distinguish `float` and `integer`, we cannot either convert between them nor render regarding to their type. See [#59](https://github.com/harttle/liquidjs/issues/59).
+* [.to_liquid()](https://github.com/Shopify/liquid/wiki/Introduction-to-Drops) has a `.toLiquid()` alias and and the JavaScript `.toString()` is aliased to `.to_s()`.
+* [.to_s()](https://www.rubydoc.info/gems/liquid/Liquid/Drop) uses `JSON.prototype.stringify` as default, rather than Ruby's inspect.

+
+## Render from String
+
+Install as Node.js dependency:
+
+```bash
+# You'll need a promise-polyfill for Node.js < 4
+npm install --save liquidjs
+```
+
+Parse and Render:
+
+```javascript
+var Liquid = require('liquidjs');
+var engine = Liquid();
+
+engine
+    .parseAndRender('{{name | capitalize}}', {name: 'alice'})
+    .then(console.log);
+
+// outputs 'Alice'
+```
+
+Caching templates:
+
+```javascript
+var tpl = engine.parse('{{name | capitalize}}');
+engine
+    .render(tpl, {name: 'alice'})
+    .then(console.log);
+
+// outputs 'Alice'
+```
+
+## Render from File
+
+```javascript
+var engine = Liquid({
+    root: path.resolve(__dirname, 'views/'),  // dirs to lookup layouts/includes
+    extname: '.liquid'          // the extname used for layouts/includes, defaults ""
+});
+engine.renderFile("hello.liquid", {name: 'alice'})
+    .then(console.log)  // outputs "Alice"
+
+// which is equivalent to: 
+engine
+    .renderFile("hello", {name: 'alice'})
+    .then(console.log)  // outputs "Alice"
+```
+
+## Use with Express.js
+
+```javascript
+// register liquid engine
+app.engine('liquid', engine.express()); 
+app.set('views', './views');            // specify the views directory
+app.set('view engine', 'liquid');       // set to default
+```
+
+[Here](demo/express/)'s an Express demo. When used with Express.js,
+Express [`views`][express-views] will be included when looking up
+partials(includes and layouts).
+
+## Use in Browser
+
+You can get a dist file for browsers from
+
+* [Releases][releases] page for liquidjs, or
+* unpkg.com: <https://unpkg.com/liquidjs/dist/liquid.min.js> 
+
+Here's the demo:
+
+* JSFiddle: <https://jsfiddle.net/6u40xbzs/> 
+* Demo directory: [/demo/browser/](demo/browser/).
+
+Note: For [IE and Android UC][caniuse-promises] browser, you will need a [Promise polyfill][pp].
+
+## Include Partials
+
+```
+// file: color.liquid
+color: '{{ color }}' shape: '{{ shape }}'
+
+// file: theme.liquid
+{% assign shape = 'circle' %}
+{% include 'color' %}
+{% include 'color' with 'red' %}
+{% include 'color', color: 'yellow', shape: 'square' %}
+```
+
+The output will be:
+
+```
+color: '' shape: 'circle'
+color: 'red' shape: 'circle'
+color: 'yellow' shape: 'square'
+```
+
+## Layout Templates (Extends)
+
+```
+// file: default-layout.liquid
+Header
+{% block content %}My default content{% endblock %}
+Footer
+
+// file: page.liquid
+{% layout "default-layout" %}
+{% block content %}My page content{% endblock %}
+```
+
+The output of `page.liquid`:
+
+```
+Header
+My page content
+Footer
+```
+
+* It's possible to define multiple blocks.
+* block name is optional when there's only one block.
+
+## Options
+
+The full list of options for `Liquid()` is listed as following:
+
+* `root` is a directory or an array of directories to resolve layouts and includes, as well as the filename passed in when calling `.renderFile()`.
+If an array, the files are looked up in the order they occur in the array.
+Defaults to `["."]`
+
+* `extname` is used to lookup the template file when filepath doesn't include an extension name. Eg: setting to `".html"` will allow including file by basename. Defaults to `""`.
+
+* `cache` indicates whether or not to cache resolved templates. Defaults to `false`.
+
+* `dynamicPartials`: if set, treat `<filepath>` parameter in `{%include filepath %}`, `{%layout filepath%}` as a variable, otherwise as a literal value. Defaults to `true`.
+
+* `strict_filters` is used to enable strict filter existence. If set to `false`, undefined filters will be rendered as empty string. Otherwise, undefined filters will cause an exception. Defaults to `false`.
+
+* `strict_variables` is used to enable strict variable derivation. 
+If set to `false`, undefined variables will be rendered as empty string.
+Otherwise, undefined variables will cause an exception. Defaults to `false`.
+
+* `trim_tag_right` is used to strip blank characters (including ` `, `\t`, and `\r`) from the right of tags (`{% %}`) until `\n` (inclusive). Defaults to `false`.
+
+* `trim_tag_left` is similiar to `trim_tag_right`, whereas the `\n` is exclusive. Defaults to `false`. See [Whitespace Control][whitespace control] for details.
+
+* `trim_value_right` is used to strip blank characters (including ` `, `\t`, and `\r`) from the right of values (`{{ }}`) until `\n` (inclusive). Defaults to `false`.
+
+* `trim_value_left` is similiar to `trim_value_right`, whereas the `\n` is exclusive. Defaults to `false`. See [Whitespace Control][whitespace control] for details.
+
+* `greedy` is used to specify whether `trim_left`/`trim_right` is greedy. When set to `true`, all consecutive blank characters including `\n` will be trimed regardless of line breaks. Defaults to `true`.
+
+## Register Filters
+
+```javascript
+// Usage: {{ name | uppper }}
+engine.registerFilter('upper', v => v.toUpperCase())
+```
+
+Filter arguments will be passed to the registered filter function, for example:
+
+```javascript
+// Usage: {{ 1 | add: 2, 3 }}
+engine.registerFilter('add', (initial, arg1, arg2) => initial + arg1 + arg2)
+```
+
+See existing filter implementations here: <https://github.com/harttle/liquidjs/blob/master/filters.js>
+
+## Register Tags
+
+```javascript
+// Usage: {% upper name%}
+engine.registerTag('upper', {
+    parse: function(tagToken, remainTokens) {
+        this.str = tagToken.args; // name
+    },
+    render: function(scope, hash) {
+        var str = Liquid.evalValue(this.str, scope); // 'alice'
+        return Promise.resolve(str.toUpperCase()); // 'Alice'
+    }
+});
+```
+
+* `parse`: Read tokens from `remainTokens` until your end token.
+* `render`: Combine scope data with your parsed tokens into HTML string.
+
+See existing tag implementations here: <https://github.com/harttle/liquidjs/blob/master/tags/>
+
+## Plugin API
+
+A pack of tags or filters can be encapsulated into a **plugin**, which will be typically installed via npm.
+
+```javascript
+engine.plugin(require('./some-plugin'));
+
+// some-plugin.js
+module.exports = function (Liquid) {
+    // here `this` refers to the engine instance
+    // `Liquid` provides facilities to implement tags and filters
+    this.registerFilter('foo', x => x);
+}
+```
+
