-# Dotfiles
+# Dockerize the Dotfiles
 
-It's time to create your own dotfiles. [This blog post by Anish Athalye](https://www.anishathalye.com/2014/08/03/managing-your-dotfiles/) demonstates the necessity and fun to tweak and optimize one's own dotfiles.
+Have you ever been in a situation where you need to reconfigure your
+development environment every time you face a new machine? The relentless cycle
+of package installations, dotfile transfers, and occasionally wrestling with
+network proxies can be downright maddening. But worry not, we can harnessed the
+power of Docker, to deliver a solution that will forever change the way you set
+up your development environment. With just one command, you can wave goodbye to
+the days of manual configuration.
 
-Dotfiles need to be easy to manage and udpate. Here are some amazing management suites for dotfiles:
+## Quick Start
 
-- [rcm](https://github.com/thoughtbot/rcm)
-- [dotbot](https://github.com/anishathalye/dotbot)
+First, ensure that you have Docker installed. If you're using the apt package
+manager, you can do so with the following command:
 
-## Learn from Others' Configurations
+```
+sudo apt install docker.io
+```
+
+Now, you're ready to begin using our Dockerized Dotfiles. Start by running this
+command:
+
+```
+docker run -it -v $(pwd):/work -v $HOME/.ssh:/home/ubuntu/.ssh --name box wongsingfo/dotfiles
+```
 
-- https://github.com/anishathalye/dotfiles
-- https://github.com/thoughtbot/dotfiles
+To detach from the container, use the default key combination: Ctrl-P followed
+by Ctrl-Q.
 
-## Docker
+If you need to re-enter the container, execute the following:
 
 ```
-sudo apt install docker.io
+# We change the detach keys to avoid the confliction with the `Previous` command in the shell
+docker start -i --detach-keys='ctrl-z,e' box
+```
 
-docker run -it -v $(pwd):/work --name box wongsingfo/dotfiles
+## Troubleshhot
+
+### Permission Issues
+
+If you encounter permission problems, it may be because the container uses the
+user ID 1000 by default, and the files under $(pwd) do not belong to this user.
+One solution is to modify the user ID of the 'ubuntu' user inside the
+container:
+
+```
+# Suppose the user ID of the current user is 1004
 sudo su -c 'usermod -u 1004 ubuntu && groupmod -g 1004 ubuntu'
-rm -rf /tmp/fish.ubuntu
 
-docker start -i --detach-keys='ctrl-z,e' box
+# Flush the Fish shell cache
+rm -rf /tmp/fish.ubuntu
 ```
+
