Macro to identify relevant rows

Hi everyone! I'm new to excel macros and so I apologize if this question is silly but any help or advice you have would be great.

I have a workbook that contains a worksheet called "Config #1" which is made up of 400+ lines of data. However, only approximately 40 of these lines are relevant for other users and these need to be summarized on another worksheet entitled "Main Sheet". The tricky part is that the relevant lines are not always the same (meaning there's always 40 but it's not always the same 40).

I would like a to create a macro that will search column B in worksheet "Config #1" and identify rows that are flagged (at the moment I'm using a Y/N indicator, "Y" implying it's a relevant row). Then, for all the rows with a Y in column B I'd like the data from columns C, E, and F to be sent to the worksheet "Main Sheet" and placed in columns B, C, and D (rows 15-34) respectively.

It is entirely possible I don't even need a macro for this but it seems like it would make things simpler. Thanks so much for your help!

Update: I've attached a simplified (sorry, it's really dummy info) version of what I need. As you can see in the file, the "Y" lines of sheet Config #1 are summarized in the table in "Main Sheet". I need a macro that will allow me to update this table as the Y/N of each line is changed. Thanks again!
