Welcome to Wikidata, Olivier!
Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!
Need some help getting started? Here are some pages you can familiarize yourself with:
- Introduction – An introduction to the project.
- Wikidata tours – Interactive tutorials to show you how Wikidata works.
- Community portal – The portal for community members.
- User options – including the 'Babel' extension, to set your language preferences.
- Contents – The main help page for editing and using the site.
- Project chat – Discussions about the project.
- Tools – A collection of user-developed tools to allow for easier completion of some tasks.
Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.
If you have any questions, don't hesitate to ask on Project chat. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.
Best regards! Cycn
If you were not already using it, you may want to check out the merge.js gadget for merging items. It has an option "Request deletion for extra items on RfD" to automatically nominate the page you are merging from for deletion. This way of nominating also makes it easier for the admins to process such requests. For support and other options you can check the help page about merging.
