+## Related to containers
+
+OK, now, we have another issue since we detect CPU features on installation.
+
+What if we want to build the container image, says Docker image, locally but deploy on a server.  
+Chances are our workstation is using more recent CPU than the server.
+
+I would recommend recompilation on container starts, simply do:
+~~~
+bundle exec gem pristine sleeping_kangaroo12
+~~~
+before the command, you actually want to run.  
+This will trigger the recompilation of SleepingKangaroo12.

+## About CPU Throttling
+
+At the time of this writing, if you use a lot of AVX-512, your CPU would heat up significantly; this leads to frequency throttling.
+
+If you plan to use KangarooTwelve heavily yet still have other functionalities impacted by lower CPU frequencies
+(like [Cloudflare](https://blog.cloudflare.com/on-the-dangers-of-intels-frequency-scaling/)),
+you may want to customize the build to prevent the throttling.
+
+If that is the case, please check [konsolebox/digest-kangarootwelve-ruby](https://github.com/konsolebox/digest-kangarootwelve-ruby).
+At the time of this writing, they offer customizable build; in contrast, SleepingKangaroo12 will focus on ease of use.
