Since 3rd of December 2015 free SSL certificates are available for everyone at letsencrypt.org
Would be nice to have a tutorial that explains the manual installation process.

First you need to clone the repo

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt

Now we are going to create a certificate


./letsencrypt-auto certonly --rsa-key-size 4096

Now, please follow the instructions. When it's finished you will be able to find the certificate, chain and key at /etc/letsencrypt/live/domain


./letsencrypt-auto --apache --rsa-key-size 4096

Now, please follow the instructions. Let's Encrypt will install the certificate automatically.

In this tutorial, we will show you how to use Let's Encrypt to obtain a free SSL certificate and use it with Nginx on Ubuntu 14.04. We will also show you how to automatically renew your SSL certificate. If you're running a different web server, simply follow your web server's documentation to learn how to use the certificate with your setup.
