+## Manual installation
+
+Install ROS Melodic according to the [documentation](http://wiki.ros.org/melodic/Installation), then [create a Catkin workspace](http://wiki.ros.org/catkin/Tutorials/create_a_workspace).
+
+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
+```

-# `clover` ROS package
-
-A bundle for autonomous navigation and drone control.
-
-## Manual installation
-
-Install ROS Melodic according to the [documentation](http://wiki.ros.org/melodic/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 SITL, use:
-
-```bash
-roslaunch clover sitl.launch
-```
-
-To start connection to the flight controller, use:
-
-```bash
-roslaunch clover clover.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`.

-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).
-* `~sleep_time` (*float*) – duration of sleep in loop cycles, used for navigate-like blocks (default: 0.2).
-
-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.

-# Blockly [![Build Status]( https://travis-ci.org/google/blockly.svg?branch=master)](https://travis-ci.org/google/blockly)
-
-
-Google's Blockly is a web-based, visual programming editor.  Users can drag
-blocks together to build programs.  All code is free and open source.
-
-**The project page is https://developers.google.com/blockly/**
-
-![](https://developers.google.com/blockly/images/sample.png)
-
-Blockly has an active [developer forum](https://groups.google.com/forum/#!forum/blockly).  Please drop by and say hello. Show us your prototypes early; collectively we have a lot of experience and can offer hints which will save you time. We actively monitor the forums and typically respond to questions within 2 working days.
-
-Help us focus our development efforts by telling us [what you are doing with
-Blockly](https://developers.google.com/blockly/registration).  The questionnaire only takes
-a few minutes and will help us better support the Blockly community.
-
-Cross-browser Testing Platform and Open Source <3 Provided by [Sauce Labs](https://saucelabs.com)
-
-We support IE11 and test it using [BrowserStack](https://browserstack.com)
-
-Want to contribute? Great! First, read [our guidelines for contributors](https://developers.google.com/blockly/guides/modify/contributing).
-
-## Releases
-
-The next major release will be **June 26th, 2020**.
-
-We release by pushing the latest code to the master branch, followed by updating our [docs](https://developers.google.com/blockly) and [demo pages](https://blockly-demo.appspot.com). We typically release a new version of Blockly once a quarter (every 3 months). If there are breaking bugs, such as a crash when performing a standard action or a rendering issue that makes Blockly unusable, we will cherry-pick fixes to master between releases to fix them. The [releases page](https://github.com/google/blockly/releases) has a list of all releases.
-
-Releases are tagged by the release date (YYYYMMDD) with a leading '2.' and a trailing '.0' in case we ever need a major or minor version (such as [2.20190722.1](https://github.com/google/blockly/tree/2.20190722.1)). If you're using npm, you can install the ``blockly`` package on npm: 
-```bash
-npm install blockly
-```
-
-### New APIs
-
-Once a new API is merged into master it is considered beta until the following release. We generally try to avoid changing an API after it has been merged to master, but sometimes we need to make changes after seeing how an API is used. If an API has been around for at least two releases we'll do our best to avoid breaking it.
-
-Unreleased APIs may change radically. Anything that is in `develop` but not `master` is subject to change without warning.
-
-### Branches
-
-There are two main branches for Blockly.
-
-**[master](https://github.com/google/blockly)** - This is the (mostly) stable current release of Blockly.
-
-**[develop](https://github.com/google/blockly/tree/develop)** - This is where most of our work happens. Pull requests should always be made against develop. This branch will generally be usable, but may be less stable than the master branch. Once something is in develop we expect it to merge to master in the next release.
-
-**other branches:** - Larger changes may have their own branches until they are good enough for people to try out. These will be developed separately until we think they are almost ready for release. These branches typically get merged into develop immediately after a release to allow extra time for testing.
-
-## Issues and Milestones
-
-We typically triage all bugs within 2 working days, which includes adding any appropriate labels and assigning it to a milestone. Please keep in mind, we are a small team so even feature requests that everyone agrees on may not be prioritized.
-
-### Milestones
-
-**Upcoming release** - The upcoming release milestone is for all bugs we plan on fixing before the next release. This typically has the form of `year_quarter_release` (such as `2019_q2_release`). Some bugs will be added to this release when they are triaged, others may be added closer to a release.
-
-**Bug Bash Backlog** - These are bugs that we're still prioritizing. They haven't been added to a specific release yet, but we'll consider them for each release depending on relative priority and available time.
-
-**Icebox** - These are bugs that we do not intend to spend time on. They are either too much work or minor enough that we don't expect them to ever take priority. We are still happy to accept pull requests for these bugs.
