Installing YunoHost manually

Once you have access to a command line on your server (either directly or through SSH), you can install yunohost by running command as root :

bash <(wget -q -O- https://install.yunohost.org/)

(If wget is not installed on your system, you might need to install it with apt-get install wget)

Once the installation is finished, you may want to proceed to post-installation

Note for advanced users concerned with the curl|bash approach

If you strongly object to the curl|bash way (and similar commands) of installing software, consider reading "Is curl|bash insecure?" on Sandstom's blog, and possibly this discussion on Hacker News.
