+
+> Plugin for creating block-level custom containers for [markdown-it](https://github.com/markdown-it/markdown-it) markdown parser.
+
+__v2.+ requires `markdown-it` v5.+, see changelog.__
+
+With this plugin you can create block containers like:
+
+```
+::: warning
+*here be dragons*
+:::
+```
+
+.... and specify how they should be rendered. If no renderer defined, `<div>` with
+container name class will be created:
+
+```html
+<div class="warning">
+<em>here be dragons</em>
+</div>
+```
+
+Markup is the same as for [fenced code blocks](http://spec.commonmark.org/0.18/#fenced-code-blocks).
+Difference is, that marker use another character and content is rendered as markdown markup.
+
+
+## Installation
+
+node.js, browser:
+
+```bash
+$ npm install markdown-it-container --save
+$ bower install markdown-it-container --save
+```
+
+
+## API
+
+```js
+var md = require('markdown-it')()
+            .use(require('markdown-it-container'), name [, options]);
+```
+
+Params:
+
+- __name__ - container name (mandatory)
+- __options:__
+   - __validate__ - optional, function to validate tail after opening marker, should
+     return `true` on success.
+   - __render__ - optional, renderer function for opening/closing tokens.
+   - __marker__ - optional (`:`), character to use in delimiter.
+
+
+## Example
+
+```js
+var md = require('markdown-it')();
+
+md.use(require('markdown-it-container'), 'spoiler', {
+
+  validate: function(params) {
+    return params.trim().match(/^spoiler\s+(.*)$/);
+  },
+
+  render: function (tokens, idx) {
+    var m = tokens[idx].info.trim().match(/^spoiler\s+(.*)$/);
+
+    if (tokens[idx].nesting === 1) {
+      // opening tag
+      return '<details><summary>' + md.utils.escapeHtml(m[1]) + '</summary>\n';
+
+    } else {
+      // closing tag
+      return '</details>\n';
+    }
+  }
+});
+
+console.log(md.render('::: spoiler click me\n*content*\n:::\n'));
+
+// Output:
+//
+// <details><summary>click me</summary>
+// <p><em>content</em></p>
+// </details>
+```
