+# Enable and Install EPEL repo on AWS EC2 Amazon Linux 2 instance
+**Step 1.** Firstly, check if the EPEL repository is enabled:
+
+```sh
+sudo amazon-linux-extras list | grep epel
+```
+
+If you get an output like:
+```
+24  epel      available    [ =7.11  =stable ]
+```
+
+Then it means that you should enable it before installing Nginx.
+
+**Step 2.** To enable the EPEL repo on Amazon Linux 2 instance run:
+
+```sh
+sudo amazon-linux-extras enable epel
+```
+
+**Step 3.** Now you should be able to install the EPEL repo:
+```sh
+sudo yum install epel-release
+```
+
+# Install Nginx on AWS EC2 Amazon Linux 2 instance
+Step 1. Once the EPEL repo is installed you can install the Nginx latest version as well:
+```sh
+sudo yum install nginx
+```
+
+Step 2. Verify the installation:
+```sh
+nginx -v
+```
+
+Output:
+```
+nginx version: nginx/1.20.1
