Take the Agenda and use that as headings with the numbers.
Add the date/time/location.
Add names of attendees (and initials so you don't have to keep typing the full names).
Did anybody declare interests? If they did, say so, if not 'No interests were declared'.
Go to each heading and find what sounds like it related to that subject. Just type the paragraph, you can move it later. Make it simple language, don't fluff it up yet. If there were things they intend to do afterwards, have a line at the end saying
ACTION: Mangle the worblegrummit - AB.
Copy the bold actions into a list at the end of the document (or beginning, if that's the format they usually take).
If you need to described a ten minute diversion where they were all arguing and trying to blame one another/the Chair was just wittering on about what a marvellous person he is, say
'The proposal to offer the Chief Fuzzledungler a purple unicorn for his actions in ensuring the dungler didn't defuzzle the worblegrummit was robustly discussed
ACTION: Chief Fuzzledungler Remuneration - to be discussed at next meeting' and
'The Chair shared experiences from the Conbulationatoryfic Atrroppication sector'
You can, instead of transcribing a full row about what the Hell some ridiculously expensive bit of kit is for, have

A. That is uncertain at this time (FP)
ACTION: Tribblipolituoloplipic spuldgeriifier purpose to be investigated and clarified in next meeting - CD
For the bits you can find no trace of 'To be discussed at next meeting' or where they've been banging on about something when they were supposed to be discussing something else 'Discussed under 5.0'
Finish with
Any Other Business. Otherwise known as 'the shit they've sprung on the committee without warning or documentation in the hope it'll be agreed without proper scrutiny'

The actions sheet. If you do it as a table, you can copy things over onto the next meeting quickly.
Then go back and try to work out what the rest of the burble was and where it fits.
