did you work it out? - I too am looking for instruction of the actual program settings as downloaded instructions dont open.
If you are using WP, then keep the file zipped on your file explorer, then open your plugins and up the top it says upload a new plugin - click there and access your computer, upload the file zipped as its too big once opened?
then it should install easily - mine did with no errors.
I have set it all up, and it posts well with fb & IG as quick posts, but am struggling to set up the timed delayed set up - it didnt post this morning as set. so if you have any further knowledge, please get back to me - maybe we can work it out together? cheers Jen - me@jenniferwilliams.com.au
