Add-ins
An add-in is a software component that increases the functionality of larger programs. It is a term frequently
used by Microsoft and other platforms that allow for the addition of extra features to core programs. An add-
in has specific, limited features that consume less memory. An add-in is installed separately and cannot be
used independently. Once installed, the add-in merges with the main software. For example, Microsoft Excel
uses a lot of add-ins for a variety of purposes.
How to manage and install add-ins:
Step 1: Click File → Options → Add-Ins.
Step 2: Select an add-in type and click on Go.
Step 3: Select the add-ins to add, remove, load, or upload. You can also browse to locate add-ins to install.
You can download a variety of Add-ins from:

SNIPPET
A "snippet" is a small, reusable piece of code that can be integrated into a larger code base. Developers talk about
snippets with specific functionality, and how snippets can be implemented when building larger, more complex programs.
Snippets have several uses. Some snippets of text editors and other software programs manage specific document
processing tasks. Some snippets can be integrated into programs such as Visual Studio and reused in projects running
within that platform.
