The OnitX CLM Clause Library is a powerful repository which stores clauses you can insert into your contract document. It is accessible from the Clause Library icon on the Add-In sidebar or from the Clause Library tile on the Document Details screen. 

Clicking either the icon or tile brings up the Clause Library screen. 

Simply place your cursor where you want to place a clause and insert the clause from the library. In the screenshot below, the cursor is placed between sections 2.4 and 2.5.

The result is the Confidentiality clause is now inserted into the contract document. This clause becomes the new 2.5 section.  

At any time the clause can be modified to reflect the user's preferred terms and language.
