| # Welcome to Flang's documentation |
| |
| Flang is LLVM's Fortran frontend that can be found |
| [here](https://github.com/llvm/llvm-project/tree/main/flang). It is often |
| referred to as "LLVM Flang" to differentiate itself from ["Classic |
| Flang"](https://github.com/flang-compiler/flang) - these are two separate and |
| independent Fortran compilers. LLVM Flang is under active development. While it |
| is capable of generating executables for a number of examples, some |
| functionality is still missing. See [Getting Involved](GettingInvolved) for tips |
| on how to get in touch with us and to learn more about the current status. |
