AI assistance is used to keep them in good shape: reviewing grammar, finding outdated commands and versions, adding missing pages and linking related content. The code and the procedures are meant to be tested before you use them in production, and corrections are always welcome at [javierruizjimenez.com](https://www.javierruizjimenez.com/). **Entries drafted with AI.** Some entries, mainly glossary pages and tutorials added after the move from WordPress, were drafted with the help of AI and have not yet been reviewed by the author. These pages show the notice "This entry was drafted with the help of AI and is pending review by the author." at the top. The notice is removed once Javier has reviewed and corrected the entry, so treat the commands and details on flagged pages with extra care and test them before relying on them. ## Contact To work with Javier, read his writing or get in touch, visit [javierruizjimenez.com](https://www.javierruizjimenez.com/).
