-**netdata** visualizes the **truth of now** in its **greatest detail**, so that you can get insights of what is happening now and what just happened, on your systems and applications:
-
- - real-time, per second updates, snappy refreshes!
- - 300+ charts out of the box, 2000+ metrics monitored!
- - zero configuration, zero maintenance, zero dependencies!
- - dozens of health monitoring alarms, out of the box!
+ - **Stunning interactive bootstrap dashboards**<br/>2 themes are provided: dark, light
+ - **Blazingly fast visualization**, it responds to all queries in less than 0.5 ms per metric, even on low-end hardware
+ - **Highly efficient data collection**, it collects thousands of metrics per server per second, with just 1% CPU utilization of a single core on modern hardware
+ - **Sophisticated alarming**, supporting dynamic thresholds, hysteresis, templating, multiple notification methods
+ - **Extensible**, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin, BASH, python, perl, node.js, java, Go, etc)
+ - **Zero configuration**, it auto-detects everything, out of the box it can detect up to 5000 metrics per server organized
+ - **Zero dependencies**, it is even its own web server for its static web files and its web API
+ - **Zero maintenance**, you just run it, it does the rest
+ - **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
+ - **Custom dashboards**, that can be built using simple HTML (no javascript necessary)
+ - **scales to infinity**, requiring minimal central resources!

-## Features
-
-This is what you get:
-
-- **Stunning bootstrap dashboards**, out of the box (theme-able: dark, light)
-- **Blazingly fast** and **super efficient**, mostly written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM)
-- **Zero configuration** - you just install it and it auto-detects everything
-- **Zero dependencies**, it is even its own web server for its static web files and its web API
-- **Zero maintenance**, you just run it, it does the rest
-- **Custom dashboards** that can be built using simple HTML (no javascript necessary)
-- **Extensible**, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin - from BASH to python and node.js, so you can easily monitor any application, any API)
-- **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
-- **Powerful alarms and notifications**, it can send alarms as email, slack.com messages, pushover.net mobile push notifications, telegram.org messages, and more.
