 # sold linker
 
-_sold_ is a fork of [mold](https://github.com/rui314/mold) that supports
-not only Linux but also macOS/iOS. Originally, _sold_ was available under
-a commercial license. Now, it has been relicensed under the MIT license.
-
-## How to build
-
-The build instruction for sold is the same as for mold except that you check
-out `https://github.com/bluewhalesystems/sold.git` instead of
-`https://github.com/rui314/mold.git`. For the details, please see
-https://github.com/rui314/mold#how-to-build.
-
-## How to use
-
-sold is installed under several different executable names as follows:
-
-1. `ld.sold`: GNU ld-compatible linker for Linux and other ELF-based systems.
-   The instructions to use sold on Linux is the same as the mold linker.
-   For the details, see the [mold's README](https://github.com/rui314/mold).
-
-2. `ld64.sold`: Apple's ld-compatible mode for macOS/iOS. You can use the
-   linker on macOS by adding `--ld-path=path/to/ld64.sold` to the linker flags.
-
-3. `ld.mold` and `ld64.mold`: They are just aliases for `ld.sold` and
-   `ld64.sold`, respectively.
+_sold_ is a high-performance linker for macOS. I built it because Apple's ld
+was too slow at the time, and I wasn't aware that they were developing a new
+linker. Xcode 15 or later are shipped with Apple's new faster linker.
+I recommend using that instead.
