# User Manual Each version of emCA includes user manuals covering five key roles: CA Administrator, Administrator, Officer, Operator, and Auditor. These manuals provide details such as login, application setup, screenshots, features, functionalities, and the roles and responsibilities associated with each user. They serve as a reference to help users understand and perform their tasks within the application. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://emca.emudhra.com/previous-release-versions/v4.2.1/user-manual.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
