+# modrinth-enhanced - Modrinth Enhanced (https://github.com/Felitendo/Modrinth-Enhanced),
+# the Modrinth App (Tauri) with a series of patches applied: no ads, no
+# telemetry, offline and Ely.by accounts, Linux fixes.
+#
+# Source package: upstream is not a fork but a patch series on top of a
+# modrinth/code release tag. The PKGBUILD takes the patches from the Modrinth
+# Enhanced release tag, applies them to the modrinth/code tarballs the same way
+# upstream's scripts/prepare.sh does and builds the result like
+# scripts/build.sh - the binary upstream wraps into the .deb that
+# modrinth-enhanced-bin repackages.
+#
+# Two modrinth/code releases are pinned per version, both read from the
+# release tag: upstream.txt is the release it was built on, patches/base.txt
+# the one the patches were last exported against. They differ until the
+# patches are exported again after Modrinth ships a release; the PKGBUILD then
+# downloads both and rebases the patches from one onto the other.
+#
+# Release/version handling is identical to modrinth-enhanced-bin: a revision
+# of the patches is tagged v0.21.2-2 and becomes pkgver 0.21.2.r2. See
+# modrinth-enhanced-bin/pkg.sh.
