> We just added a new minibook to the webpage’s learn category: [Fortran Best Practice](https://fortran-lang.org/learn/best_practices). This book was originally part of [fortran90.org](https://www.fortran90.org/src/best-practices.html) and has been almost completely reworked for addition to the webpage. Many thanks go to Vincent @vmagnin for translating the reStructuredText files to markdown and of course all the reviewers that helped getting the minibook into shape. There is still work to be done, I already opened a few follow-up issues (contributions are welcome): [Fortran Best Practice: Type…](https://github.com/fortran-lang/fortran-lang.org/issues/309)
