-## Understand the Dependencies
-
-To help users understand the dependencies, we are trying to compile a high
-level [dependency graph](dependencies.dot). You can build your own Dockerfile or
-ISO package according to it.
-
-To view the graph, please run:
-
-```bash
-sudo apt -y install xdot
-xdot dependencies.dot
-```
-
-## Add New Dependency
-
-When you need to add something to the Docker image or Bazel `WORKSPACE` file, it's
-defined as a new dependency. Before doing that, please add it as well as all its
-dependencies to the `dependencies.dot` first, so we understand all the
-dependencies and dependents, which helps us manage its lifecycle like upgrading
-and retiring in the future.

 ## Add New Installer
 
 The best practice of a new installer would be:

docker/build/dependencies.dot

-digraph {
-  "infra" -> "bazel 0.5.3";
-  "bazel 0.5.3" -> "GCC 4.8";
-  "infra" -> "glog 0.3.5" -> "gflags 2.2" -> "cmake";
-  "infra" -> "protobuf 3.3";
-  "infra" -> "gtest 1.8" -> "absl 20180600";
-
-  "cyber" -> "infra";
-  "cyber" -> "FastRTPS 1.5.0" -> "Fast CDR";
-  "cyber" -> "POCO Foundation";
-  "cyber" -> "python3-dev";
-  "cyber" -> "uuid-dev";
-
-  "modules" -> "multiple" -> "boost 1.54/1.65";
-  "multiple" -> "pcl 1.9.1";
-
-  "modules" -> "perception" -> "cuda 10.0";
-  "perception" -> "opencv 2.4.8";
-
-  "offline" -> "bosfs 1.0.0";
-  "caffe 1.0" -> "protobuf";
