   git clone https://github.com/kelunik/acme-client
   – cd to acme folder
   cd acme-client
   – Download and install the composer
   php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');";
php composer-setup.php;
php -r "unlink('composer-setup.php');";
php composer.phar install --no-dev
3. Generating SSL Certificate
php bin/acme setup --server letsencrypt --email [email protected]
php bin/acme issue --domains yourdomain.com:www.youdomain.com --path /home/x123011738/public_html:/home/x123011738/public_html --server letsencrypt
cd /home/x123011738/acme-client/data/certs/acme-v01.api.letsencrypt.org.directory/yourdomain.com
cat fullchain.pem
cat key.pem
4. Installing Certificat
   – click SSL button
   
   – Paste contents from certificate.txt to Certificate:(CRT) and contents from privatekey.txt to Private Key:(KEY)
   
5. Checking expiration date and renewing SSL certificate
   php acme-client/bin/acme check --name yourdomain.com --server letsencrypt
   – you can set cron job to run the following command every other month
php acme-client/bin/acme issue --domains yourdomain.com:www.yourdomain.com --path /home/x123011738/public_html:/home/x123011738/public_html --server letsencrypt
