Running the jar is the way you first get NetKernel running. For just reading documentation or have a browse this is fine. However you will not be able to update your instance from the repository or make any changes including starting developing without installing.
If you haven't already installed NetKernel then it is recommended you do so now otherwise you will not be able to install updates, start development or make any changes to your instance.
NetKernel hosts it's own installer. Install NetKernel by clicking on the main NetKernel logo in the navigation bar (or click here) and select the "Install NetKernel" option near the top of the page:
For more information please see this Installation Video Tutorial.
After installation NetKernel automatically connects to the Apposite repository to look for software updates.
We highly recommend that you look at the Apposite Panel and accept all available updates. This will ensure your system has all the latest packages.
NetKernel is a modular software platform; with the Apposite package manager you can discover, add and remove packages of modules quickly and easily. Like a Linux distribution, you can install additional modules with programming languages, domain specific toolkits, network transports, client-side protocol services, etc. You can also install tutorials, demonstrations and full applications.
Packages for NetKernel are located in repositories which can be browsed using Apposite or discovered using the integrated search engine. If you are looking for something specific, try a search by entering a term or phrase in the search box located at the top of any page in NetKernel. For example, enter Jabber in the search box at the top of this page and hit the search button. You will see a list of reference; the top one is the description of the Jabber module.
You can try adding some applications to NetKernel. Click on an application link below and you will be taken to its package installation page within Apposite. Once on the installation page, select the "install" option (in the left hand margin) and then click "Apply Selections" to download and install the package.
Uninstalling a package is just as easy - find its name in Apposite and select "uninstall". Even easier, click "History" and rollback NetKernel to its system state before you installed it!
