+## Server specs
+Raspberry Pi 5 with a 120 GB SSD[^1] running latest Raspbian[^2]
+
+## Setup
+I can't tell you where it's hosted, other than it's in a closet[^3], but I can tell you how:
+
+Basically there's a single docker compose file for the whole stack:
+- forgejo - what you're looking at
+- mariadb
+- nginx - web server, it supports http3 (github doesn't)
+- acme - renews ssl certificate
+
+There's also a VPS:
+- it's what you connect to when visiting this site
+- is connected to the rpi by WireGuard.[^4]
+- limits network speed to 50 Mbps[^5]
+- ipv6[^6] is forwarded and ipv4 is NATed
+
+Mail is from mxroute, but I also use it for other purposes, so it's like free
+
+Total cost: I just can't use the raspberry pi for fun stuff anymore
+
+[^1]: sata adaptered to usb 3
+[^2]: now known as uncool Raspberry Pi OS
+[^3]: at home if you didn't deduce that from "raspberry pi"
+[^4]: Precisely the rpi connects to it because NAT
+[^5]: (slightly less than github)
+[^6]: what github STILL doesn't have
