 ## Docker
 
-The community also maintains a docker image (`manimcommunity/manim`), which can be found [on DockerHub](https://hub.docker.com/r/manimcommunity/manim). The following tags are supported:
-
-- `latest` -- the most recent version corresponding to [the main branch](https://github.com/ManimCommunity/manim)
-- `stable` -- the latest released version (according to [the releases page](https://github.com/ManimCommunity/manim/releases))
-- `vX.Y.Z` -- any particular released version (according to [the releases page](https://github.com/ManimCommunity/manim/releases))

-### Instructions for running the docker image
-
-#### Quick Example
-To render a scene `CircleToSquare` in a file `test_scenes.py` contained in your current working directory while preserving your user and group ID, use
-
-```sh
-docker run --rm -it  --user="$(id -u):$(id -g)" -v "$(pwd)":/manim manimcommunity/manim manim test_scenes.py CircleToSquare -qm
-```
-
-#### Running the image in the background
-
-Instead of using the "throwaway container" approach sketched above, you can also create a named container that you can also modify to your liking. First, run
-
-```sh
-docker run -it --name my-manim-container -v "$(pwd):/manim" manimcommunity/manim /bin/bash
-```
-
-to obtain an interactive shell inside your container allowing you to, e.g., install further dependencies (like texlive packages using `tlmgr`). Exit the container as soon as you are satisfied. Then, before using it, start the container by running
-
-```sh
-docker start my-manim-container
-```
-
-Then, to render a scene `CircleToSquare` in a file `test_scenes.py`, call
-
-```sh
-docker exec -it --user="$(id -u):$(id -g)" my-manim-container manim test.py CircleToSquare -qm
-```
-
-#### Jupyterlab
-
-Another alternative is to use the docker image to spin up a local webserver running
-JupyterLab in whose Python kernel manim is installed and can be accessed via the `%%manim` cell magic.
-To use JupyterLab, run
-
-```sh
-docker run -it -p 8888:8888 manimcommunity/manim jupyter lab --ip=0.0.0.0
-```
-
-and then follow the instructions in the terminal.
-
-#### Important notes
-
-When executing `manim` within a Docker container, several command line flags (in particular `-p` (preview file) and `-f` (show output file in the file browser)) are not supported.
+The community also maintains a docker image (`manimcommunity/manim`), which can be found [on DockerHub](https://hub.docker.com/r/manimcommunity/manim).
+Instructions on how to install and use it can be found in our [documentation](https://docs.manim.community/en/stable/installation/docker.html).
