+# Install Intel® Clear Containers 3.0 on RHEL
+
+## Pre-requisites
+
+Install Docker-EE or Docker-CE on RHEL.
+
+## Required setup
+
+You are required to run the `sudo` command without specifying a password
+to set up the Clear Containers 3.X installation. Verify this requirement
+with the following commands:
+```
+$ su -
+# echo "$some_user ALL=(ALL:ALL) NOPASSWD: ALL" | (EDITOR="tee -a" visudo)
+$ exit
+
+```
+
+The following steps show you how to install Clear Containers 3.X
+
+1. Ensure the system packages are up-to-date:
+
+```
+$ sudo yum -y update
+
+```
+2. Install Git:
+
+```
+$ sudo yum install -y git
+
+```
+3. Create the installation directory and clone the repository:
+
+```
+$ mkdir -p $HOME/go/src/github/clearcontainers
+$ cd $HOME/go/src/github/clearcontainers
+$ git clone https://github.com/clearcontainers/runtime
+$ cd runtime
+
+```
+4. Run the installation script:
+
+```
+$ script -efc ./installation/rhel-setup.sh
+
+```
+
+Note:
+
+- The `script(1)` command not strictly necessary to run the installation script but
+using this command writes a log of the installation to the `typescript`. Administrators might
+find the log useful to see the changes made and when debugging issues.
+
+Verify the Clear Containers 3.X installation is successful:
+
+1. Check the `cc-runtime` version:
+
+```
+$ cc-runtime --version
+
+```
+
+2. Test that a Clear Container can be created:
+
+```
+$ sudo docker run -ti busybox sh
+
+```
