 # Computational Category Theory
 
+## Open the project up in GitHub
+In GitHub, click on the green "Code" button above, choose the "codespaces" tab instead of "local" and create a new Codespace on the main branch.
+## Alternative (compose)
+`docker`/`podman` compose can also be used instead to run locally
+
+## Getting Started
+
 Link to [Catlab](https://algebraicjulia.github.io/Catlab.jl/stable/) documentation.
+
+The main notebook is [working_file/notebook.ipynb](working_file/notebook.ipynb), run the cells there and make sure they show the graphs as required.
