Adding generic source files to your project, you need to insert topic IDs in your source code.

• Insert the Topic Identifier and the name of the source code symbol in the first line of your comments. The default Topic Identifier is (@@).
• To insert text that is not associated to a specific symbol, assign a topic ID to your topic.

Assume you have a function Encrypt:

Doc-O-Matic detects the identifier only, if he is the first string of a line, no white spaces are allowed between the identifier and the beginning of the line. All text between an identifier line and the next identifier line is taken as description. 

After successfully assigning topic IDs to your comments, Doc-O-Matic the Content Manager displays your topics in the topic hierarchy and the Topic Preview displays your comments.
