+# Base ansible role
+
+This installs a bunch of packages that I will probably need quite soon,
+and configures some services such as:
+
+* Fail2ban
+* cronie
+* paccache cron
+* sslh (with a default config that is only sent if there is none already available)
+* nftables (with a default config that is only sent if there is none already available)
+* uptimed
+* vnstat
+
+It also installs yay.
