You need to download and install desktop now.sh app. It will provide command line utility called now.

When it has been installed deploy procedure becomes incredibly easy.

Just compile your site (build it):

$ cd ~/Sites/site

$ cogear build

It will be compiled to the output folder which is ./public by default.

Now you are ready to deploy.

$ now --public public

You send the command to Now to upload the folder ./public in --public mode (it's required for non-paid accounts).

Within a few seconds, your site is online!

Site address has been copied to the clipboard.

You may choose an appropriate domain with now alias command.

$ now alias https://public-psuaoefsus.now.sh cogear.now.sh

Done!

You can even use custom domain via DNS management.

Like I do:

$ now alias https://public-psuaoefsus.now.sh cogearjs.org

Cogear.JS official site is hosted at Now.sh absolutely for free.
