 * '''SIF Compatibility''' - The target machine must be running a linux operating system (OS) and have Singularity or Apptainer installed - using the same version of the '''.sif''' image file format. (See  [https://apptainer.org/docs/user/main/singularity_compatibility.html#sif-image-compatibility| SIF Image Compatibility] in Apptainer documentation.)
+
 * '''Machine Architecture''' - Your image file may not run on the target machine's architecture, x86/amd64 (for Intel/AMD) or arm64 (for Apple), if it is not the same as that of the machine on which the image file was constructed.
  * For linux platform architecture, use the command '''uname -m'''.
  * For linux kernel version use, use the command '''uname -r'''.
+
 * '''Container Security''' - Because Singularity runs entirely inside your Linux user space (see [https://www.linfo.org/user_space.html| User Space Definition]), the container instantly inherits your identity, your permissions, and your network access. This includes your Cypress account's access to files and internet.
+
+* '''Avoid using the :latest for production or research''' - The images whose name ends with the tag ''':latest''' can change over time, reducing reproducibility and making it difficult to know exactly what software was reviewed, tested, or approved. Whenever possible, use an image tagged with a specific version, such as '''ubuntu:14.04''' rather than '''ubuntu:latest'''.
