-With our scalable contact solver framework 🧩 and purely web-based frontends 🌐, this limitation is reduced. Our solver also runs on an NVIDIA L4 🖱️, a data-center designed GPU that offers reasonable pricing 💲, delivering both satisfactory performance 💪 and practical scalability 📈.
+- Quickly deploy testing environments 🚀 and delete them when not in use, saving costs 💰.
+- Scale as needed based on demand 📈. For example, you can create multiple instances to perform numerous tasks before a specific deadline ⏰.
+- Design a fully automated pipeline 🔄 for trial-and-error iterations without human involvement 🤖.
+- Allow anyone with an internet connection 🌍 to try our solver, even on a smartphone 📱 or tablet 🖥️.

+The code is not lengthy.
+If possible, we also strongly suggest following the official instructions to install them.
+These commands exist because this is exactly how we initiate our development environment for all new containers.
 
 Once you have a [💤 LazyVim](http://www.lazyvim.org/) environment installed in the container, turn on the `clangd` and `rust` plugins.

 ## 📡 CLI Instructions on Cloud Services
 
-This article summarizes how to deploy our solver on major cloud platforms using the provided CLI. With this CLI, we can:
-
-- Quickly deploy a testing environment and delete it when not in use, saving costs.
-
-- Scale as needed based on demand. For example, you can create multiple instances to perform numerous tasks before a specific deadline.
-
-- Design a fully automated pipeline to enable trial-and-error iterations without human involvement.
+This article summarizes how to deploy our solver on major cloud platforms using the provided CLI.
+The CLI enables faster and more consistent creation and deletion of instances. It can also be extended to create a cleaner UI that facilitates instance management.
