§ 326 Charge to grand jury.

When a grand jury is formed and sworn in, the judge has to explain their job to them before they start working. The judge tells them what they are supposed to do as grand jurors and walks them through this responsibility.

The judge also gives the grand jury details about any criminal charges that have already been brought to the court, or charges that might come up while they are serving. This helps the grand jurors understand what kinds of cases they may need to review and decide on.

Basically, this rule makes sure grand jurors don't go into their service blind. The judge sets them up with the information they need to do their job properly from the start.
