For the second year in a row, Chipotle will donate 50 percent of the proceeds from meals purchased at D.C. locations Tuesday to the city’s libraries.

The promotion runs from 11 a.m. to 10 p.m. at every D.C. Chipotle. Diners need to show the below flyer, either on a phone or printed out, to make their meal benefit the D.C. Public Library Foundation. The burrito chain will donate up to $5,000.

You likely don’t need this, but here’s a map of locations.

Update: Yes.

Second update: For real.
