 # POSIM — Platform for Ocean Simulation
 
 POSIM is an open-source maritime robotics simulation library maintained by
-IOES-Lab. It brings together ocean worlds, underwater vehicles, sensors, and
-manipulation tasks for ROS 2 and Gazebo.
-
-POSIM continues the [DAVE](https://github.com/IOES-Lab/dave) codebase, originally
-developed as [Project DAVE](https://github.com/Field-Robotics-Lab/dave). This
-repository preserves the source history, existing copyright notices, and
-Apache-2.0 license.
-
-## Current development version
-
-The `main` branch targets **Ubuntu 26.04, ROS 2 Lyrical, and Gazebo Jetty**.
-The initial POSIM import is based on DAVE `ros2` commit
-[`8a3f6ab`](https://github.com/IOES-Lab/dave/commit/8a3f6abc2ba14ced787aff8befa0201f6c80ca8c).
-POSIM 1.0 has not been released.
-
-ROS packages, plugin namespaces and launch files use the `posim_` prefix.
-Rebuild in a clean workspace when migrating from the earlier `dave_` names.
-Existing third-party source attribution is retained.
-
-## Get started
-
-1. Run `extras/ros-lyrical-gz-jetty-install.sh`, or build `.docker/lyrical.amd64.dockerfile` / `.docker/lyrical.arm64v8.dockerfile` from this checkout.
-2. Open a terminal with the installed ROS and workspace environments loaded.
-3. Start a world:
-
-   ```bash
-   ros2 launch posim_demos posim_world.launch.py world_name:=posim_ocean_waves
-   ```
-
-For a server-only run, append `headless:=true`. On a desktop with rendering
-available, start REXROV with:
-
-```bash
-ros2 launch posim_demos posim_robot.launch.py \
-  namespace:=rexrov world_name:=posim_ocean_waves z:=-5 paused:=false
-```
-
-World and model references may download assets from Gazebo Fuel on first use.
-More examples are in [the demo guide](examples/posim_demos/README.md).
-
-## Library contents
-
-- `models/`: world, vehicle, sensor, and object descriptions and their resources.
-- `gazebo/`: model, sensor, world, ROS bridge, and multibeam sonar plugins.
-- `examples/posim_demos/`: world, robot, sensor, and object launch entry points.
-- `posim_interfaces/`: ROS messages and services used by the library.
-- `extras/`: dependency installation, repository manifests, and development tools.

+simulated sensors, and ROS 2 control interfaces for Gazebo.
 
 ## Documentation
 
-Read the [English guide](website/content/en/index.md) or
-[한국어 가이드](website/content/ko/index.md) for installation, examples, custom
-models and plugin references. The guides adapt the IOES-Lab Notion Wiki to
-the current source layout.

+**[한국어 문서](https://ioes-lab.github.io/POSIM/ko/)**
 
-The [documentation website](website/README.md) uses the WWW-POSIM documentation
-design and provides search, command copying and mobile navigation. It builds
-to static HTML and can be deployed independently on Vercel or another static
-host. Building it does not build or run Gazebo.
+Find installation instructions, first simulations, vehicle and sensor examples,
+custom robot guides, and plugin references on the documentation website.
+The `main` branch targets Ubuntu 26.04, ROS 2 Lyrical, and Gazebo Jetty.
+Start with [installation](https://ioes-lab.github.io/POSIM/install.html) or
+[Docker](https://ioes-lab.github.io/POSIM/docker.html), then run your
+[first simulation](https://ioes-lab.github.io/POSIM/quickstart.html).
