User or technical documentation for Data Capture for DHIS2

Good day DHIS2 community. I have downloaded and trying out the Data Capture for DHIS2 application in Google Play. I wish to inquire if there are other related documentation for this application aside from the one found on this URL: http://www.dhis2.org/doc/snapshot/en/user/html/ch24s02.html ?

Thank you very much.
