There are two standard way of entering worklogs, one is using worklog dialog on the issue screen and the other one is logging work as a part of issue transition on issue transition screen. Since WorklogPRO adds a link to main issue page for opening worklog dialog probably you will immediately notice it and you will start to use it immediately. On this dialog you can specify worklog attributes when logging work (for example type of work performed or whether it is billable or not). If you are using worklog attributes you will also need to specify worklog attributes when logging work on transition screens when resolving an issue, verifying an issue etc. To be able to specify work log attributes you will need to add "Log Work Custom Field" provided by WorklogPRO to your corresponding transition screens.
Adding this custom field is no different than adding other custom fields and explained in Jira manual. Here a close outline of how to do it for WorklogPRO's "Log Work Custom Field":
Functionality of this field is very similar to 'Log Work Dialog', you can refer to that section for learning more about how to enter work logs.
