 #### Modern
 
-The Modern folder stores our new design, re-using the same Dockerfile for any compiler version. Consider this folder for new projects, as we will maintain it for a long period. All images generated by modern design are named using the compiler name, version, distro and its version, e.g. `conanio/gcc11-ubuntu16.04`. Only x64 is supported. Please, read the issue [#205](/~https://github.com/conan-io/conan-docker-tools/issues/205) to obtain more information about our decision related to design, distro version, glibc support, system package and compilers.

 After many updates, new compiler releases, instability and incompatibility problems, we decided to clean the house, move a step forward with Conan Docker Tools. So far, we usually follow the same recipe, when a compiler version is released, we also release a new docker image, but we have two main problems:
