 As this is a 3rd party plugin you'll need to build caddy (or use the binaries).
-To build with this plugin you'll need to have go1.19 installed.
+To build with this plugin you'll need to have `Golang v1.19` installed. Basic idea:

+### Build with locally cloned plugin sources

+
+```Dockerfile
+FROM caddy:2.8.4-builder-alpine AS builder
+
+COPY gitea-pages.go go.mod go.sum /module/gitea-pages/
+COPY pkg/gitea/*                  /module/gitea-pages/pkg/gitea/
