Hi,

I am trying to register a (small) package I wrote for time series analysis. I am using it as a backend for more sophisticated algorithms that I plan to release on GitHub in the next couple of months.

I am in the process of creating the Project.toml file. However, I am not sure where can I find the correct UUID. Would you please explain to me where can I find it?

Thank you.

As far as I know, your package does not have a UUID until you create one, so there is no correct UUID for you to find. You can use `Pkg.generate("YourPackageName")` which will generate a Project.toml with a valid UUID field, but as far as I know that’s just generating an almost-certainly-unique random string in the right format.

It should also be fine to do `using UUIDs; uuid4()`.

I would recommend using one of the package template generators, eg

> **[GitHub - JuliaCI/PkgTemplates.jl: Create new Julia packages, the easy way](https://github.com/JuliaCI/PkgTemplates.jl)**
>
> Create new Julia packages, the easy way. Contribute to JuliaCI/PkgTemplates.jl development by creating an account on GitHub.

or

> **[GitHub - tpapp/PkgSkeleton.jl: Generate Julia package skeletons using a...](https://github.com/tpapp/PkgSkeleton.jl)**
>
> Generate Julia package skeletons using a simple template system - GitHub - tpapp/PkgSkeleton.jl: Generate Julia package skeletons using a simple template system

(disclaimer: I am the author of the latter).

It will make other things, like CI setup, easier, and also generate a starting Project.toml for you.
