+### Saving Plots As HTML
+
+```julia
+p = plot(y=rand(10))
+
+PlotlyLight.save(p, "myplot.html")
+```
+
+- Note: call `PlotlyLight.preset.source.standalone!()` first if you want the html file to contain the entire plotly.js script.  This enables you to view the plot even without internet access.
+
+
+### Save Plots as Image via [PlotlyKaleido.jl](https://github.com/JuliaPlots/PlotlyKaleido.jl)
+
+```julia
+using PlotlyKaleido
+
+PlotlyKaleido.start()
+
+(;data, layout, config) = p
+
+PlotlyKaleido.savefig((; data, layout, config), "myplot.png")

+# Settings
+
+Occasionally the `PlotlyLight.preset`s aren't enough.  Low level user-configurable settings are available in `PlotlyLight.settings`:
+
+```julia
+PlotlyLight.settings.src::Cobweb.Node           # plotly.js script loader
+PlotlyLight.settings.div::Cobweb.Node           # The plot-div
+PlotlyLight.settings.layout::EasyConfig.Config  # default `layout` for all plots
+PlotlyLight.settings.config::EasyConfig.Config  # default `config` for all plots
+PlotlyLight.settings.reuse_preview::Bool        # In the REPL, open plots in same page (true, the default) or different pages.
+```
+
+Check out e.g. `PlotlyLight.Settings().src` to examine default values.

+# Plotly.js Source Presets
+
+Change how the plotly.js script gets loaded in the produced html via `preset.source.<option>!()`.
+
+```julia
+preset.source.none!()       # Don't include the script.
+preset.source.cdn!()        # Use the official plotly.js CDN.
+preset.source.local!()      # Use a local version of the plotly.js script.
+preset.source.standalone!() # Copy-paste the plotly.js script into the html output.
