+sqm_lagthrottle - a CAKE SQM Bandwidth Manager
+==============================================
+
+This project aims to provide an effective control loop for efficiently adapting
+bandwidth caps for the CAKE Smart Queue Management system to work with. Its
+primary deployment target is OpenWrt routers.
+
+This is **ALPHA QUALITY SOFTWARE**, and will still undergo a lot of changes.
+If you find it interesting, please check back every once in a while and see if
+there were any updates published.

+The software is developed, tested and used primarily on OpenWrt 21.02 and
+later.
+
+
+Requirements
+------------
+
+`sqm_lagthrottle` was designed to require minimal additional depencies on top
+of what regular OpenWrt installations/images will provide. It checks for all
+required external programs during startup, and the only additional OpenWrt
+package you should be required to installed is **fping**.
+
+
+Getting Started
+---------------
+
+Using `sqm_lagthrottle` requires some preparation and configuration. First, you
+will need to place both `sqm_lagthrottle.sh` and `__sqm_lagthrottle.awk` in the
+same directory. You are highly encouraged to also fetch and place
+`sqm_lagthrottle_suggest_config.sh` next to it, as this helper program will
+assist you during the configuration phase.
+
+Now, try to keep the traffic on your Internet uplink to a minimum over the next
+few minutes, and invoke `sqm_lagthrottle_suggest_config.sh`. After it finishes
+running, it will present you with a configuration file that you should rename
+to `sqm_lagthrottle.conf`, where it will override any values that are set by
+default in `sqm_lagthrottle.sh`.
+
+Next, open `sqm_lagthrottle.sh` in the text editor of your choice, and set the
+remaining configuration values (or, at your option, copy them over into
+`sqm_lagthrottle.conf`, and adapt them to your needs there. What you will need
+to get right at a minimum are the setting for interfaces to control bandwith
+for, and the interface statistics files to read bandwidth usage data from. All
+configuration values are documented inline.
+
+Once this is work is done, you can start `sqm_lagthrottle.sh` to observe its
+output and effect.
+
+Please provide feedback and comments to me on irc (in #openwrt on OFTC) or at
+the official OpenWrt forums at https://forum.openwrt.org/ - my registered
+nickname reads `colo` in both places.
