-## Running wpantund from a Docker container:
-
-For a device that has a Thread radio attached to port `/dev/ttyUSB0`, start `wpantund` as follows:
-
-```
-docker run --rm --detach -e "OPENTHREAD_DEVICE_PORT=/dev/ttyUSB0" --cap-add=NET_ADMIN --device=/dev/ttyUSB0 --name=wpantund openthread/wpantund
-```
-
-Once `wpantund` is running, one can control the Thread interface with `wpanctl` as follows:
-
-```
-docker exec -it wpantund wpanctl
-```
-
-## Content
-
-arm32v7_ubuntu_wpantund
-
-- `wpantund` running on ARMv7 (e.g. Raspberry Pi)
-
-x86_ubuntu_wpantund
-
-- `wpantund` running on x86
-
-ot_sim
-
-- OpenThread POSIX simulator
-
-codelab_otsim
-
-- For use with the [Docker Simulation Codelab](https://codelabs.developers.google.com/codelabs/openthread-simulation/), contains the OpenThread POSIX example and `wpantund` pre-built and ready to use.
-
-environment

-## Starting simulator
-
-To start the OpenThread simulator, run:
-
-```
-docker run --rm -d --name otsim openthread/simulation tail -F /dev/null
-```
-
-or
-
-```
-./start_sim
-```
-
-This runs in background a docker container with environment setup to simulate OpenThread nodes.
-
-## Adding a Thread node
-
-To start simulating an OpenThread node #1, run:
-
-```
-docker exec -it otsim node 1
-```
-
-or
-
-```
-./add_node 1
-```
-
-This runs a program called node, which is an OpenThread FTD binary, inside the docker container's simulator environment.
-
-## Stopping simulator
-
-To stop the OpenThread simualtor, run:
-
-```
-docker stop otsim
-```
-
-or
-
-```
-./stop_sim
-```
-
-This stop the docker daemon process.
