I was adding this package:

> **[GitHub - luchr/ComplexPortraits.jl: Domain coloring for complex functions](https://github.com/luchr/ComplexPortraits.jl)**
>
> Domain coloring for complex functions. Contribute to luchr/ComplexPortraits.jl development by creating an account on GitHub.

```julia
using Pkg
Pkg.add(PackageSpec(url="https://github.com/luchr/ComplexPortraits.jl", rev="master"))

```

it is cloning the github and build it and precompile it.

If I download a package (any Julia package form github) in zip, how to add it, precompile and build ?

For example this DynamicalSystems:

> **[GitHub - JuliaDynamics/DynamicalSystems.jl: Award winning software library...](https://github.com/JuliaDynamics/DynamicalSystems.jl)**
>
> Award winning software library for nonlinear dynamics and nonlinear timeseries analysis - GitHub - JuliaDynamics/DynamicalSystems.jl: Award winning software library for nonlinear dynamics and nonli...

can I just download from the github and do some commands to make it build and precompile based on the zip that I downloaded? Do I need to download the dependencies packages related to DynamicalSystems too?

You can just do `Pkg.add("path/to/downloaded/directory")` and Pkg will add the package, download dependencies from its `Project.toml` file and be good to go.

If you intend to edit the package code locally, you can also use `Pkg.dev` so that it stays in sync with your changes.

I want to know is it possible to add (offline) the whole package’ dependencies from bottom food chain that has no dependency ? so no need to download dependencies.
