Quick Installation
=====================
If ``certbot`` (or ``letsencrypt``) is packaged for your Unix OS (visit
certbot.eff.org_ to find out), you can install it
from there, and run it by typing ``certbot`` (or ``letsencrypt``). Because
not all operating systems have packages yet, we provide a temporary solution
via the ``certbot-auto`` wrapper script, which obtains some dependencies from
your OS and puts others in a python virtual environment::
user@webserver:~$ wget https://dl.eff.org/certbot-auto
user@webserver:~$ chmod a+x ./certbot-auto
user@webserver:~$ ./certbot-auto --help
.. hint:: The certbot-auto download is protected by HTTPS, which is pretty good, but if you'd like to
double check the integrity of the ``certbot-auto`` script, you can use these steps for verification before running it::
user@server:~$ wget -N https://dl.eff.org/certbot-auto.asc
user@server:~$ gpg2 --recv-key A2CFB51FA275A7286234E7B24D17C995CD9775F2
user@server:~$ gpg2 --trusted-key 4D17C995CD9775F2 --verify certbot-auto.asc certbot-auto
And for full command line help, you can type::
./certbot-auto --help all
``certbot-auto`` updates to the latest client release automatically. And
since ``certbot-auto`` is a wrapper to ``certbot``, it accepts exactly
the same command line flags and arguments. More details about this script and
other installation methods can be found `in the User Guide
<https://certbot.eff.org/docs/using.html#installation>`_.
