+### Rebuilding the base image
+
+If you ever wish to rebuild the base image, you should get a tool named [buildx](https://github.com/docker/buildx). It should be attached with the docker desktop app on the Mac OS, but if you use Linux, you will probably need to install it manually. For the installation instructions, please go [here](https://github.com/docker/buildx#installing).
