README

Leaflet was created in 2010 by Volodymyr Agafonkin, a Ukrainian citizen living in Kyiv.

Russia's full-scale invasion of Ukraine began in February 2022 and is still going. Russian troops have killed tens of thousands of civilians and committed mass war crimes. Missiles and drones still hit Kyiv and other Ukrainian cities day and night.

Leaflet is used for documenting Russia's war crimes, tracking the front line and finding humanitarian aid. The future of Ukraine is the future of Leaflet.

If you'd like to help, donate to Come Back Alive or another charity listed on StandWithUkraine, and keep asking your government to support Ukraine and pressure Russia. Just don't be silent.

Yours truly,
Leaflet maintainers.
