 Hello everybody to the NFCore infrastructure group. We are mainly working with the tools, NFCore tools, but also NF validation and some parts of NF test and also the website. So it doesn't matter if it's in the Python, Groovy or JavaScript and HTML or CSS, you will find stuff to work in this group, all these skills. And we have everything nicely gathered and our project board, it's the infrastructure project board and we have different subgroups, so if you feel lost, just like try to stick to one subgroup and work your way through it, we will have enough issues for everybody there. But yes, talk more about NF validation, please Nikolas. So if you want to work on NF validation, you can pick one issue from words you see there. For example, the one, link to the Slack channel on the website, on the docs. If you want to do that, you can assign yourself by clicking on add assignees, like so. And that way you will tell everyone I'm working on this issue so we don't do double work, etc. If you want to add a new issue, you can also click on add item in the overview, a bit down, yes there, add item. So you can do what you want. If you want any help, you can hit any of us up, especially I will be working on NF validation, so you can ask me if you want anything. So next. Good, yes. Dan, we have many subgroups for the tools because there are many ties we touch with this and Julia will talk about this more. Yes, so for working in NF card tools, you have for so easy issues and for beginners, we have some issues about documentation or then also some good first issues. For example, we have this one where we would need to change how GitHub changes between dark mode or light mode images and then other different things you can work on. For example, some bugs that we have selected that would be interesting, like small projects to work during the hackathon and you can also work on adding new commands, for example this NFCore sub-workflows patch that we already have an NFCore modules patch, but we would need to implement this one for sub-workflows and then also adding some new features and working on linting tests or CI tests for tools and so just pick one issue that you like. Yes, or if you don't like command line but like web development, we have also quite a few stuff, a few things with the website, especially because we just launched a new one and one thing for example, which would be if you are OK with regular expressions, we have these admonitions but also GitHub has these admonitions and the syntax is not the same, so it would be good if we could still use basically the same syntax, especially for the read maze to render them nicely in both sites on GitHub but also on the website. So this is just some regex work and I think a good first issue for that. And then we also have things about the schema or NF test, but more about that you will hear about in the NF test group and that is pretty much it or NF core infrastructure. So yeah, if you have any questions, just drop by on our Slack channel, the hackathon, or up to us if you're in Barcelona. Cool, thank you very much. Bye. See you.
