About Leaflet
From the project's README at github.com/Leaflet/Leaflet. Lightly cleaned for readability; for the full source see the upstream repo.
Leaflet was created in September 2010, 15 years ago, by Volodymyr Agafonkin, a Ukrainian citizen living in Kyiv.
Russian bombs are now falling over Volodymyr's hometown. His family, his friends, his neighbours, thousands and thousands of absolutely wonderful people, are either seeking refuge or fighting for their lives.
Russian soldiers have already killed tens of thousands of civilians, including women and children, and are committing mass war crimes like gang rapes, executions, looting, and targeted bombings of civilian shelters and places of cultural significance. The death toll keeps rising, and Ukraine needs your help.
> If you want to help, educate yourself and others on the Russian threat, follow reputable journalists, demand severe Russian sanctions and Ukrainian support from your leaders, protest the war, reach out to Ukrainian friends, donate to Ukrainian charities. Just don't be silent.
