+# TuxCare Radar
+
+This guide describes [TuxCare Radar](https://tuxcare.com/radar/) and how to install and use it.
+
+## What is TuxCare Radar?
+
+TuxCare Radar is an intelligent vulnerability scanner for Linux systems, fully integrated with TuxCare's live patching and ELS technologies. It swiftly uncovers vulnerabilities and ensures their effective prioritization using a unique algorithm that assesses the risk to your company based on a comprehensive set of risk factors.
+
+## Installation
+
+If you are not already a KernelCare or ePortal user, you will first need to install our repository configuration:
+
+RPM-based distributions (AlmaLinux, RHEL etc):
+
+```text
+cat > /etc/yum.repos.d/kernelcare.repo <<EOL
+[kernelcare]
+name=kernelcare
+baseurl=https://repo.cloudlinux.com/kernelcare/\$releasever/\$basearch
+enabled=1
+gpgcheck=1
+gpgkey=https://repo.cloudlinux.com/kernelcare/RPM-GPG-KEY-KernelCare
+EOL
+```
+
+For APT-based distributions (Debian, Ubuntu etc):
+
+```text
+curl -s https://repo.cloudlinux.com/kernelcare/kernelcare.gpg -o /usr/share/keyrings/kcare.gpg
+
+source /etc/os-release
+
+if [ "$ID" = "debian" ]; then export VERSION_CODENAME=kcare; fi
+
+printf '%s' \
+  "deb [signed-by=/usr/share/keyrings/kcare.gpg] " \
+  "https://repo.cloudlinux.com/kernelcare/kernelcare-$ID/$VERSION_ID " \
+  "$VERSION_CODENAME main" > /etc/apt/sources.list.d/kcare.list
+```
+
+If you are already a KernelCare user or have followed the above repo instructions, you should be able to install Radar as simply as running one of the following:
+
+RPM-based distributions (AlmaLinux, RHEL etc):
+
+```text
+yum install tuxcare-radar
+```
+
+For APT-based distributions (Debian, Ubuntu etc):
+
+```text
+apt-get install tuxcare-radar
+```
+
+## Configuration
+
+You should have received your initial API key (something like `bc061b2b-c330-49f6-8953-849637d593ac`) along with your password.
+
+You will need to edit /etc/tuxcare-radar/radar.yaml on each server you wish to scan using Radar and insert your API key. In most instances we would recommend doing this via a centralised config-management tool such as Ansible or Puppet, but you could of course use `vim` or `sed` on the server itself, for example:
+
+```text
+sed -i 's/apikey:.*/apikey: bc061b2b-c330-49f6-8953-849637d593ac/' /etc/tuxcare-radar/radar.yaml
+```
+
+By default the file will look like this, where `FILLME` should be replaced with your API key:
+
+```text
+base-url: https://radar.tuxcare.com
+logfile: /var/log/tuxcare-radar/radar.log
+statefile: /var/cache/tuxcare-radar/radar.json
+time-between-runs: 23h
+apikey: FILLME
+```
+
+## Usage
+
+The installer should have created an /etc/cron.d/tuxcare-radar file that will run every 4th hour, it will check if a scan has been run in the last 23 hours (`time-between-runs` in radar.yaml) and if not, it will run a scan.
+
+If you need to manually run a scan instantly for any reason, you can run:
+
+```text
+su -s /bin/bash nobody -c "tuxcare-radar --config /etc/tuxcare-radar/radar.yaml"
+```
+
+Then visit [https://radar.tuxcare.com](https://radar.tuxcare.com/) to view the results.
