Need to make sure the instructions are clear and suitable for a user who might not be very technical. Use simple language and avoid jargon where possible. Also, check if there are any specific steps unique to Office 2013 that need to be highlighted, like how saving as .txt works differently in this version compared to newer ones.
Also, considering possible misinterpretations: could "bit.ly office 2013 txt" refer to a specific text file created by Office 2013 that was shared via Bit.Ly? Or maybe the user is trying to open a .txt file in Office 2013? But that seems less likely. The user wants a guide, so step-by-step instructions would be necessary.
Finally, confirm if the user might have intended something else with their query, but given the information, proceed with the most likely scenario and create a comprehensive yet concise guide.
