This summary is not the rule. The rule text controls.
Parties in a lawsuit can agree in writing to change how discovery works, without needing the judge to approve it first (unless the judge has already said otherwise). Discovery is the process where both sides gather information and evidence before trial, like taking depositions or exchanging documents.
For example, the two sides can agree to hold a deposition at a different time, place, or in a different way than the standard rules require. If they agree to this in writing, that deposition can still be used in court just like any other deposition. This flexibility also applies to other discovery methods, not just depositions. The two sides can work out their own arrangements as long as they put it in writing and agree on it together.
The point of this rule is to save time and avoid unnecessary trips to court. If both sides can agree on how to handle discovery, they don't need a judge to step in and settle every small detail.
