Upgrading docs from Documenter.jl to DocumenterVitepress.jl 
Assuming that your current documentation is based on Documenter.jl, you can upgrade to DocumenterVitepress.jl by following these steps:
Let us suppose that you are working on a package named Example.jl that is part of a GitHub organization named ExampleOrg.
Then the very first step here is to update the make.jl file to follow the DocumenterVitepress.jl format.
- Go the the 
make.jlfile in yourdocsfolder and do the following necessary changes to upgrade to DocumenterVitepress.jl: 
The make.jl file with Documenter.jl should look like this:
julia
using Example
using Documenter
DocMeta.setdocmeta!(Example, :DocTestSetup, :(using Example); recursive=true)
makedocs(;
    modules = [Example],
    repo = Remotes.GitHub("ExampleOrg", "Example.jl"),
    authors = "Jay-sanjay <landgejay124@gmail.com>, and contributors",
    sitename = "Example.jl",
    format = Documenter.HTML(;
        canonical = "https://github.com/ExampleOrg/Example.jl",
        edit_link = "main",
        assets = String[],
    ),
    pages = [
        "Home" => "index.md",
        "Tutorials" => "tutorials.md",
        "API" => "api.md",
        "Contributing" => "contributing.md"
    ],
)
deploydocs(;
    repo = "github.com/jay-sanjay/Example.jl",
    devbranch = "main",
)stop any vitepress session
julia
# you might need to stop the Vitepress server if it's running before
# updating or creating new files
try run(`pkill -f vitepress`) catch end- Next, to build new docs from docs/src,
 
sh
$ cd docs
docs $- Then, in docs/, start a julia session and activate a new environment.
 
sh
docs $ julia
julia> ]
pkg> activate .- Add packages as necessary. Here, we will need
 
julia
pkg> add DocumenterVitepress, Documenter- Then run the 
make.jlfile to build the documentation. 
julia
julia> include("make.jl")- Finally, hit 
;to enter the shell mode and run: 
sh
shell> npm iThe above command shall create a folder named node_modules and package-lock.json in your docs folder.
- Next, hit 'Backspace' to get back to the Julia REPL and run:
 
julia
julia> DocumenterVitepress.dev_docs("build")- Finally the live preview of your documentation at 
http://localhost:5173/Example.jl/in your browser.
