 To use [Graphs of Convex Sets (GCS) Trajectory Optimization](https://drake.mit.edu/doxygen_cxx/classdrake_1_1planning_1_1trajectory__optimization_1_1_gcs_trajectory_optimization.html) in your own code, we recommend that you use the version in [Drake](http://drake.mit.edu), which is being actively developed and improved.
 
-## Versions
-
-This code has been updated since the Arxiv paper was published. The code used to run the examples in that paper can be found under the [`arxiv_paper_version`](https://github.com/mpetersen94/gcs/releases/tag/arxiv_paper_version) tag. That version was tested to work with Drake version 1.3 (although version up to 1.8 should work with some deprecation warnings).

 ## Running via Deepnote
-Most of the examples and reproductions can be run on [Deepnote](https://deepnote.com/workspace/mark-petersen-2785519d-2c3e-430b-9a10-a1754f2de37d/project/GCS-Motion-Planning-around-Obstacles-with-Convex-Optimization-3afac8e3-cbc0-41d1-9afb-0d38dfbe9ffa/).

 After duplicating the project into your own account, be sure to run the `MosekLicenseUpload.ipynb` notebook to make your Mosek License available for solving the optimization problems.
 
-Note: The PRM and Bimanual reproductions do not yet work on Deepnote and the UAV and Maze reproductions have been shrunk in size to avoid hitting memory limits on Deepnote.

 On your machine go to http://localhost:8888/ You will find the reproduction notebooks in the reproduction folder.
 
+Note: The instructions here use port 7000 for meshcat (robot visualization) and 8888 for jupyter. If these ports are already in use on your machine, you can change the `-p` flag in the `docker run` command above; for instance use `-p 7001:7000` to map the docker port 7000 to your localhost 7001 for meshcat.

 ### Option 2: Local Installation
 If you want to compare GCS to sampling based planners (such as PRM), you'll need to install a custom fork of [Drake](https://drake.mit.edu) that includes bindings for sampling based planners.  To do this run the following, including any of the proprietary solvers you have access to. You may build it with Gurobi.
