For the record, setup needed for DocumenterTools is as follows:

JuliaSIMD/SLEEFPirates.jl#15 (comment)

julia> import DocumenterTools
julia> DocumenterTools.genkeys()

2. Go to Settings > Secrets > Actions. Create a new GitHub Secret with the name DOCUMENTER_KEY where the value is the Base64-encoded private key from step 1.

3. Go to Settings > Deploy keys. Create a new deploy key with the name DOCUMENTER_KEY_PUBLIC where the value is the public key from step 1. Make sure that the deploy key has write access.

Oops, this one was actually about a DataFrame printed on Jupyter Notebook-generated markdown not being correctly rendered on the Documenter-generated page.

```julia
housing = dataset("MASS", "housing")
```
