I’m excited to announce the documenter theme Indigo: [GitHub - JuliaDiff/DocThemeIndigo.jl: The Documenter Theme for the ChainRules family of packages. But you can use it too](https://github.com/JuliaDiff/DocThemeIndigo.jl)

This is originally the theme [ChainRules](https://juliadiff.org/ChainRulesCore.jl/stable/) uses, I separate it out so that now we can use it for other packages.

## Usage

1. use `DocThemeIndigo.install` to generate the indigo CSS file
2. put the CSS file path into your assets

Your `docs/make.jl` file would look like the following

```julia
using Documenter
using DocThemeIndigo 
# 1. generate the indigo theme css
indigo = DocThemeIndigo.install(MyPackageModule)
makedocs(; 
     # ... 
     format=Documenter.HTML(; 
     # ... 
     # put your indigo css in assets
          assets=String[indigo #= your other assets =#], 
     ), 
     # ... 
)

```
