+# Installing Kata Containers on CentOS
+
+Note: Kata Containers is available for CentOS version 7.
+
+This step is only required in case Docker is not installed on the system.
+1. Install the latest version of Docker with the following commands:
+
+```bash
+$ sudo yum -y install dnf-plugins-core
+$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
+$ sudo yum -y install docker-ce
+```
+For more information on installing Docker please refer to the
+[Docker Guide](https://docs.docker.com/engine/installation/linux/centos)
+
+2. Install the Kata Containers components with the following commands:
+
+  **Note:** The repository redirects the download content to use `http`, be aware that this installation channel is not secure.
+```bash
+$ source /etc/os-release
+$ sudo -E VERSION_ID=$VERSION_ID yum-config-manager --add-repo \
+http://download.opensuse.org/repositories/home:/katacontainers:/release/CentOS_\$VERSION_ID/home:katacontainers:release.repo
+$ sudo -E yum -y install kata-runtime kata-proxy kata-shim
+```
+
+3. Configure Docker to use Kata Containers by default with the following commands:
+
+```bash
+$ sudo mkdir -p /etc/systemd/system/docker.service.d/
+$ cat <<EOF | sudo tee /etc/systemd/system/docker.service.d/kata-containers.conf
+[Service]
+ExecStart=
+ExecStart=/usr/bin/dockerd -D --add-runtime kata-runtime=/usr/bin/kata-runtime --default-runtime=kata-runtime
+EOF
+```
+
+4. Restart the Docker systemd service with the following commands:
+
+```bash
+$ sudo systemctl daemon-reload
+$ sudo systemctl restart docker
+```
+
+5. Run Kata Containers
+
+You are now ready to run Kata Containers:
+
+```
+$ sudo docker run -ti busybox sh
+```
