+    Incus is a modern, secure and powerful system container and virtual machine manager.
+    Incus is a community fork from Canonical's LXD.
+
+    It provides a unified experience for running and managing full Linux systems inside containers
+    or virtual machines. Incus supplies images for a wide number of Linux distributions and is built
+    around a very powerful, yet pretty simple, REST API. Incus scales from one instance on a single
+    machine to a cluster in a full data center rack, making it suitable for running workloads both
+    for development and in production.
+
+    Incus allows you to easily set up a system that feels like a small private cloud. You can run any
+    type of workload in an efficient way while keeping your resources optimized.
+
+    You should consider using Incus if you want to containerize different environments or run virtual
+    machines, or in general run and manage your infrastructure in a cost-effective way.
