+Improves website loading speed by lazy loading reCaptcha for Contact Form 7.
+
+## Description ##
+
+Usually, reCaptcha scripts load immediately in Contect Form 7. Regardless of whether
+you use the async or defer strategy, reCaptcha script execution requires a significant
+amount of device resources, which is very noticeable on mobile devices.
+
+The idea behind the plugin is simple: load and execute reCaptcha only when the user
+starts interacting with the contact form. This results in a significant increase in
+loading speed, but it can lead to worse spam detection (see FAQ).
+
+
+
+
+## Installation ##
+
+This section describes how to install the plugin and get it working.
+
+1. Upload `lazy-recaptcha-for-cf7.zip` to the `/wp-content/plugins/` directory and unzip it
+1. Activate the plugin through the 'Plugins' menu in WordPress
+
+## Frequently Asked Questions ##
+
+### Does it reduce the accuracy of spam detection? ###
+
+It is likely to [decrease][recaptcha docs]. Therefore, it is advisable to use this method only if there are no other ways to improve the speed.
