+# `finallycoffee.base.user` ansible role
+
+Provision and manage user accounts on the remote host. Supports setting user
+home, gecos (display name) and shell.
+
+Warning: if the users' home exists and is changed, the role will attempt to
+move the home directory. Set `move_home` to false on the user to disable this
+behaviour.
+
+## Examples
+```yaml
+- hosts: all
+  roles:
+    - role: finallycoffee.base.user
+  vars:
+    users:
+      - name: root
+      - name: alice
+      - name: bob
+        state: present
+      - name: eve
+        state: absent
+```
