-Clover is an open source [ROS](https://www.ros.org)-based framework, providing user-friendly tools to control [PX4](https://px4.io)-powered drones. Clover is available as a ROS package, but is shipped mainly as a preconfigured image for Raspberry Pi. Once you've installed Raspberry Pi on your drone and flashed the image to its microSD card, taking the drone up in the air is a matter of minutes.
+CLEVER (Russian: *"Клевер"*, meaning *"Clover"*) is an educational programmable drone kit consisting of an unassembled quadcopter, open source software and documentation. The kit includes Pixhawk/Pixracer autopilot running PX4 firmware, Raspberry Pi 3 as companion computer, a camera for computer vision navigation as well as additional sensors and peripheral devices.
 
-COEX Clover Drone is an educational programmable drone kit, suited perfectly for running clover software. The kit is shipped unassembled and includes Pixracer-compatible autopilot running PX4 firmware, Raspberry Pi 4 as a companion computer, a camera for computer vision navigation as well as additional sensors and peripheral devices. Batteries included.
+Copter Express has implemented a large number of different autonomous drone projects using exactly the same platform: [automated pizza delivery](https://www.youtube.com/watch?v=hmkAoZOtF58) in Samara and Kazan, coffee delivery in Skolkovo Innovation Center, [autonomous quadcopter with charging station](https://www.youtube.com/watch?v=RjX6nUqw1mI) for site monitoring and security, winning drones on [Robocross-2016](https://www.youtube.com/watch?v=dGbDaz_VmYU) and [Robocross-2017](https://youtu.be/AQnd2CRczbQ) competitions and many others.
 
-The main documentation is available at [https://clover.coex.tech](https://clover.coex.tech/). Official website: [coex.tech/clover](https://coex.tech/clover).
+**The main documentation is available [on Gitbook](https://clever.coex.tech/).**

+Clone this repo to directory `~/catkin_ws/src/clever`:
+
+```bash
+cd ~/catkin_ws/src
+git clone https://github.com/CopterExpress/clever.git clever
+```
+
+All the required ROS packages (including `mavros` and `opencv`) can be installed using `rosdep`:
+
+```bash
+cd ~/catkin_ws/
+rosdep install -y --from-paths src --ignore-src
+```
+
+Build ROS packages (on memory constrained platforms you might be going to need to use `-j1` key):
+
+```bash
+cd ~/catkin_ws
+catkin_make -j1
+```
+
+To complete `mavros` install you'll need to install `geographiclib` datasets:
+
+```bash
+curl https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/install_geographiclib_datasets.sh | sudo bash
+```
+
+You may optionally install udev rules to provide `/dev/px4fmu` symlink to your PX4-based flight controller connected over USB. Copy `99-px4fmu.rules` to your `/lib/udev/rules.d` folder:
+
+```bash
+cd ~/catkin_ws/src/clever/clever/config
+sudo cp 99-px4fmu.rules /lib/udev/rules.d
+```
+
+Alternatively you may change the `fcu_url` property in `mavros.launch` file to point to your flight controller device.
+
+## Running
+
+Enable systemd service `roscore` (if not running):
+
+```bash
+sudo systemctl enable /home/<username>/catkin_ws/src/clever/builder/assets/roscore.service
+sudo systemctl start roscore
+```
+
+To start connection to SITL, use:
+
+```bash
+roslaunch clever sitl.launch
+```
+
+To start connection to the flight controller, use:
+
+```bash
+roslaunch clever clever.launch
+```
+
+> Note that the package is configured to connect to `/dev/px4fmu` by default (see [previous section](#manual-installation)). Install udev rules or specify path to your FCU device in `mavros.launch`.
+
+Also, you can enable and start the systemd service:
+
+```bash
+sudo systemctl enable /home/<username>/catkin_ws/src/clever/deploy/clever.service
+sudo systemctl start clever
+```

- * @brief Clip a line against a clip plane.
- *
- * This function "clips" a line (described by two points in *camera space*)
- * against a clip plane that is `clipPlaneDistance` meters away from the
- * camera focal point. If both points are further away from the focal point
- * than `clipPlaneDistance`, they will be returned unmodified. If one of the
- * points is behind the clipping plane, a point *on* the clipping plane will
- * be computed and returned as one of the points.
- *
- * If none of the points are visible, an empty vector will be returned.
- *
- * @param p1 First point on the line, in camera space.
- * @param p2 Second point on the line, in camera space.
- * @param clipPlaneDistance Distance from the focal point to the clipping plane.
- * @return A vector of zero or two points on the clipped line, in camera space.

-# `clover` ROS package
-
-A bundle for autonomous navigation and drone control.
-
-## Manual installation
-
-Install ROS Noetic according to the [documentation](http://wiki.ros.org/noetic/Installation), then [create a Catkin workspace](http://wiki.ros.org/catkin/Tutorials/create_a_workspace).
-
-Clone this repo to directory `~/catkin_ws/src/clover`:
-
-```bash
-cd ~/catkin_ws/src
-git clone https://github.com/CopterExpress/clover.git clover
-```
-
-All the required ROS packages (including `mavros` and `opencv`) can be installed using `rosdep`:
-
-```bash
-cd ~/catkin_ws/
-rosdep install -y --from-paths src --ignore-src
-```
-
-Build ROS packages (on memory constrained platforms you might be going to need to use `-j1` key):
-
-```bash
-cd ~/catkin_ws
-catkin_make -j1
-```
-
-To complete `mavros` install you'll need to install `geographiclib` datasets:
-
-```bash
-curl https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/install_geographiclib_datasets.sh | sudo bash
-```
-
-You may optionally install udev rules to provide `/dev/px4fmu` symlink to your PX4-based flight controller connected over USB. Copy `99-px4fmu.rules` to your `/lib/udev/rules.d` folder:
-
-```bash
-cd ~/catkin_ws/src/clover/clover/config
-sudo cp 99-px4fmu.rules /lib/udev/rules.d
-```
-
-Alternatively you may change the `fcu_url` property in `mavros.launch` file to point to your flight controller device.
-
-## Running
-
-To start connection to the flight controller, use:
-
-```bash
-roslaunch clover clover.launch
-```
-
-For the simulation information see the [corresponding article](https://clover.coex.tech/en/simulation.html).
-
-> Note that the package is configured to connect to `/dev/px4fmu` by default (see [previous section](#manual-installation)). Install udev rules or specify path to your FCU device in `mavros.launch`.

-Blockly programming support for Clover.
-
-<img src="screenshot.png" width=700>
-
-See user documentation at the [main Clover documentation site](https://clover.coex.tech/en/blocks.html).
-
-Internal package documentation is given below.
-
-## Frontend
-
-The frontend files are located in [`www`](./www/) subdirectory. The frontend application uses [`roblib.js`](http://wiki.ros.org/roslibjs) library for communicating with backend node and other ROS resources.
-
-## `clover_blocks` node
-
-`clover_blocks` is the blocks programming backend, implementing all the services and topics needed for running Blockly-generated Python script.
-
-### Services
-
-* `~run` ([*clover_blocks/Run*](srv/Run.srv)) – run Blockly-generated program (in Python).
-* `~stop` ([*std_srvs/Trigger*](http://docs.ros.org/melodic/api/std_srvs/html/srv/Trigger.html)) – terminate the running program.
-* `~store` ([*clover_blocks/load*](srv/Store.srv)) – store a user program (to `<package_path>/programs` by default).
-* `~load` ([*clover_blocks/load*](srv/Load.srv)) – load all the stored programs.
-
-### Parameters
-
-* `~programs_dir` (*string*) – directory for user programs.
-
-Parameters read by frontend:
-
-* `~navigate_tolerance` (*float*) – distance tolerance in meters, used for navigate-like blocks (default: 0.2).
-* `~yaw_tolerance` (*float*) – yaw angle tolerance in degrees, used in set_yaw block (default: 20).
-* `~sleep_time` (*float*) – duration of sleep in loop cycles, used for navigate-like blocks (default: 0.2).
-* `~confirm_run` (*bool*) – enable confirmation to run the program (default: true).
-
-These parameters also can be set as URL GET-parameters, for example:
-
-```
-http://<hostname>/clover_blocks/?navigate_tolerance=0.5&sleep_time=0.1
-```
-
-### Topics
-
-#### Published
-
-* `~running` ([*std_msgs/Bool*](http://docs.ros.org/melodic/api/std_msgs/html/msg/Bool.html)) – indicates if the program is currently running.
-* `~block` ([*std_msgs/String*](http://docs.ros.org/melodic/api/std_msgs/html/msg/String.html)) – current executing block (maximum topic rate is limited).
-* `~error` ([*std_msgs/String*](http://docs.ros.org/melodic/api/std_msgs/html/msg/String.html)) – user program errors and exceptions.
-* `~prompt` ([*clover_blocks/Prompt*](msg/Prompt.msg)) – user input request (includes random request ID string).
-
-This topic is published from the frontend side:
-
-* `~prompt/<request_id>` ([*std_msgs/String*](http://docs.ros.org/melodic/api/std_msgs/html/msg/String.html)) – user input response.
