+Example block scaffolded with Create Block tool.
+
+== Description ==
+
+This is the long description. No limit, and you can use Markdown (as well as in the following sections).
+
+For backwards compatibility, if this section is missing, the full length of the short description will be used, and
+Markdown parsed.
+
+== Installation ==
+
+This section describes how to install the plugin and get it working.
+
+e.g.
+
+1. Upload the plugin files to the `/wp-content/plugins/key-points` directory, or install the plugin through the WordPress plugins screen directly.
+1. Activate the plugin through the 'Plugins' screen in WordPress
+
+
+== Frequently Asked Questions ==
+
+= A question that someone might have =
+
+An answer to that question.
+
+= What about foo bar? =
+
+Answer to foo bar dilemma.
+
+== Screenshots ==
+
+1. This screen shot description corresponds to screenshot-1.(png|jpg|jpeg|gif). Note that the screenshot is taken from
+the /assets directory or the directory that contains the stable readme.txt (tags or trunk). Screenshots in the /assets
+directory take precedence. For example, `/assets/screenshot-1.png` would win over `/tags/4.3/screenshot-1.png`
+(or jpg, jpeg, gif).
+2. This is the second screen shot
+
+== Changelog ==
+
+= 0.1.0 =
+* Release
+
+== Arbitrary section ==
+
+You may provide arbitrary sections, in the same format as the ones above. This may be of use for extremely complicated
+plugins where more information needs to be conveyed that doesn't fit into the categories of "description" or
+"installation." Arbitrary sections will be shown below the built-in sections outlined above.
