The installation of JoomTestimonials Component is pretty much straight forward and simple just as you would install other 3rd party components. Before you begin with the installation, remember to download the latest version from your account area at https://www.joomboost.com/my-products.html
Login to your Joomla back end and head on to the installation area at Extensions > Extension Manager
Step 2 (Installation by upload of package)
Locate for the package which you have downloaded earlier by clicking on the "Browse" button. Hit the Upload File & Install button.
Installation is completed now.
