 # AndroidRemoteBuildWithDocker
 
-If you build Android project on MacBook or other laptops, you must think your computer performance is not enough. Your laptop battery is not enough as well.  And you must spend a lot time on waiting it.
-So you may want a powerful and portable workstation. It is impossible. But you can build on remote desktop.
-The trouble on me as well but I fixed it. I used to take a remote-build with [Mainframer](https://github.com/buildfoundation/mainframer) on my powerful desktop.
-It is a problem that Mainframer configuring with Android will spend lost time. In case of building with a cloud service or new desktop, tremendous steps of configuration make me feel tired. Whereas a virtualization technology , such as `Docker` and `Kubernetes`, which I've used in everywhere is very efficient and easy in backup. 
-In this repo, I make a docker image for a **builder server** that contains Android environment and [Mainframer](https://github.com/buildfoundation/mainframer). You can deploy a google cloud or amazon cloud server for your remote and powerful building. Furthermore, you can run on your desktop in case you have a powerful/high-performance PC with your laptop under one LAN. It works on not only **terminal** but also **Android Studio**.

+The trouble on me as well but I fixed it. I used to establish a remote-builder on my powerful desktop. I control the remote-builder by not only terminal but also Android studio.
+A problem is that remote-builder configuring with Android will spend lots time. In building it on a cloud service or new desktop, tremendous steps of configuration make me tired. So I made this repo integrate with a couple of technologies: Docker and  [Mainframer](https://github.com/buildfoundation/mainframer).
+
+The Mainframer works for remote building. Its official explain: 
+> A tool that executes a command on a remote machine while syncing files back and forth. The process is known as remote execution (in general) and remote build (in particular cases).
+> It works via pushing files to the remote machine, executing the command there and pulling results to the local machine.
+
+And I have to tell you that it work not only temrinal but also Android studio.
+
+Before I said that remote-builder configuring with Android will spend lots time but we have virtualization technology, such as `Docker` and `Kubernetes`, which I've used in everywhere is high-performance and easy to use and backup. 
+***In this repo, I make a docker image that contains Android environment and [Mainframer](https://github.com/buildfoundation/mainframer)***. 
+You can run it on your desktop in case you have a powerful/high-performance desktop. It is not required that the desktop and your laptop **under one LAN**. In case the desktop you can connect from anywhere, it can be set the docker image. Furthermore, you can put the docker image on a cloud service, such as, google or amazon cloud server, for your remote and powerful building. Cloud services are elastic in performance and price. Besides, you may think cloud server is high-latency. I have to explain that latency won't effect your building experience because mainframer does not to communitcate your laptop many times in a building process. Even copying files only in before and after buiding build. And the full-file-copy task only once.
+
+To sum up, I explained that the repo works for remote-building. After you establish a remote-builder, you can bring you laptop to coffee shop, grass and sunshine without electric charging.
