+
+Top-like interface for container metrics
+
+`ctop` provides a concise and condensed overview of real-time metrics for multiple containers:
+<p align="center"><img src="_docs/img/grid.gif" alt="ctop"/></p>
+
+as well as a [single container view][single_view] for inspecting a specific container.
+
+`ctop` comes with built-in support for Docker and runC; connectors for other container and cluster systems are planned for future releases.

+
+## Building
+
+Build steps can be found [here][build].
+
+## Usage
+
+`ctop` requires no arguments and uses Docker host variables by default. See [connectors][connectors] for further configuration options.
+
+### Config file
+
+While running, use `S` to save the current filters, sort field, and other options to a default config path (`~/.config/ctop/config` on XDG systems, else `~/.ctop`).
+
+Config file values will be loaded and applied the next time `ctop` is started.
+
+### Options
+
+Option | Description
+--- | ---
+`-a`	| show active containers only
+`-f <string>` | set an initial filter string
+`-h`	| display help dialog
+`-i`  | invert default colors
+`-r`	| reverse container sort order
+`-s`  | select initial container sort field
+`-v`	| output version information and exit
+
