+# ArchRepo
+## Version 2
+
+### Past versions
+* Version 1 is the current version, running state-fully in a dedicated VM, which uses NFS to mount the repository (and
+thus works only on a local network)
+
+### Introduction
+Version 2 targets an all-new architecture:
+* written in Python
+* running in a container
+  * potentially a stateless and ephemeral container

+# KTO ArchRepo update script
+# version 2.0
+
+# The purpose of this script is to automate the maintenance of a custom pacman (Arch Linux) repository, whose goal is to
+# provide already built packages of AUR software.
+
+# This version 2 aims at 2 major evolutions:
+# * manage dependencies (hence Python and object-oriented programming);
+# * run this script in a stateless Arch container, rather than a full VM as in version 1.
+# Additionaly, we may like to manage working directory in a better way (check available storage space, and existing
+# directories).
+
+# This script should NOT be run as root. Or should it?
+# * We are in a stateless container, but I don't think we can run makepkg as root...
+
+# Imports
