+## 🌌 Ansible Galaxy
+
+This collection can now be used in larger ansible projects.
+
+Instructions:
+
+- create or modify a file `collections/requirements.yml` in your project
+
+```yml
+collections:
+  - name: ansible.utils
+  - name: community.general
+  - name: ansible.posix
+  - name: kubernetes.core
+  - name: https://github.com/techno-tim/k3s-ansible.git
+    type: git
+    version: master
+```
+
+- install via `ansible-galaxy collection install -r ./collections/requirements.yml`
+- every role is now available via the prefix `techno_tim.k3s_ansible.` e.g. `techno_tim.k3s_ansible.lxc`
