        <h2>What is chiselled Ubuntu</h2>
      </div>
      <div class="col-6 col-medium-3">
        <p>
          Chiselled Ubuntu is inspired by the Distroless concept - providing ultra-small OCI images with only your application and its runtime dependencies, and no other operating system-level packages or libraries. This makes them lightweight, secure, and efficient.
        </p>
        <p>
          There’s an infinite number of slices of the Ubuntu distribution. You can chisel Ubuntu for your exact needs, or rely on our set of pre-built chiselled Ubuntu runtime images.
        </p>
        <p>
          In August 2022, we released the <a href="/blog/install-dotnet-on-ubuntu">first set of pre-built chiselled Ubuntu runtime images</a> for the .NET ecosystem in collaboration with Microsoft.
