Deployment

Stable and/or signed releases may be deployed from the Chrome store or the Mozilla catalog.

To deploy the latest development version on your local machine, you can (1) either (a) clone the git source tree or (b) download a source archive, and then (2) install the extension into your Chrome or Opera browser on the same system.

Clone the git source tree

Clone the sources from github using the following commands:

$ cd src
$ git clone https://github.com/OpenLinkSoftware/OSDS_extension

which will automatically download the latest develop branch.
