-# oc-shortcode-plugin
+# Shortcodes for October CMS
+
 Adds the ability to use shortcodes within October CMS
+
+### Add new shortcodes
+
+Add the shortcode in the `boot` function of a plugin.
+
+Then, use the provided facade to add new shortcodes in your own plugins:
+
+    \Shortcode::add('code', function(ShortcodeInterface $s) {
+        $text = "<h2>Shortcode Name: {$s->getName()}</h2>";
+        $text .= "<p>Shortcode Parameter: {$s->getParameter('param', 'Not Found')}</p>";
+        $text .= "<p>Shortcode Content: {$s->getContent()}</p>";
+        return $text;
+    });
+
+The above registration would enable the following shortcode to be used:
+
+    [code param="Parameter Value"] Inside Content [/code]
+
+### Use the shortcode within a page or blog post:
+
+The usual shortcode syntax is supported via the [Thunderer\Shortcode](https://github.com/thunderer/Shortcode) project.
+
+    [code]
+    [code argument="value"]
+    [code novalue argument=simple other="complex value"]
+    [code]content[/code]
+    [code argument="value"]content[/code]
+
+### Enable shortcodes on all pages
+
+To enable shortcodes on all page rendering, go to **Shortcode Settings** in the admin settings panel and check "Enable Shortcodes on all page rendering".
+
+### Using filters and functions
+
+If you don't want to enable shortcodes on all page rendering, you can use the built-in filter or function.
+
+To use the `shortcode` filter within a blog post or page, add the `shortcode` filter before any `raw` filtering.
+
+    <div class="cp-post-content">{{ post.content_html|shortcode|raw }}</div>
+
+To use the `shortcode` function within a layout and against the October CMS `page` tag, change the `page` tag from a token to a function:
+
+    {% page %}
+
+Becomes:
+
+    {{ shortcode(page()) }}
+
+    -- or --
+
+    {{ page()|shortcode }}
+
+### Strip Shortcodes
+
+You can strip shortcodes from text using the `Shortcode::strip` function. For example, when using with the `Sensory5\BlogExtension` plugin, you can strip shortcodes from the summary using the following code:
+
+    Event::listen('sensory5.blog.summary', function($content) {
+        return Str::limit(Html::strip(\Shortcode::strip($content)), 600);
+    });
