+                            Astrolabe is a free open-source project built by a Ukrainian in Kyiv, Ukraine. 
+                            If you're thinking of donating, I should be transparent about where that money actually goes - it doesn't go to me or the project. 
+                            It goes to something I care about much more. Right now, while I've been building this passion project, there are people I know - my relatives, friends, colleagues - who took arms and joined Ukraine's Armed Forces. They're defending their country against Russian invasion. 
+                            Most of them were civilians before this. They're still civilians, really, just doing something they had to do.
+                            I feel deep gratitude to them. So my goal is to support these brave people however I can.

+                            You might wonder if the military really needs donations.
+                            The honest answer: yes. The government and Ministry of Defense cover basics, but when you're on the frontlines, every small thing matters.
+                            Better equipment, better protection, better conditions - these things can make a difference between life and death.

+                            If you have concerns about donating to the military: I get it. Not everyone is comfortable with that for various reasons, and I respect that.
+                            The good news is that many of the organizations below also run humanitarian projects for civilians affected by the war. So you have options.
