+Source tarballs for some of the ebuilds in personal overlay.
+
+This repository has Git LFS enabled, and holds source tarballs of the
+Linux-libre kernel and the corresponding GPG signatures. This keeps
+some load off of the main server, and prevents the source from
+disappearing, as sometimes the Linux-libre developers will remove
+already-released kernel sources if they discover non-Free code in it.
+
+Source tarballs for all Linux-ilbre ebuilds will be maintained in this
+repository, and the ebuilds will use this repository for `SRC_URI`.
+The ebuilds will also be updated to support the `verify-sig` USE flag,
+so authenticity of the sources can be guaranteed.
