@@ -40,7 +40,6 @@ There are some optional features that can be enabled during compilation that are
 - `ENABLE_COMPILETIME_FORMAT_CHECK`: checks for the validity of `std::format`-style format string during compilation. Enabled by default.
 - `ENABLE_PCI_IDS_DOWNLOAD`: downloads the [`pci.ids` database](https://pci-ids.ucw.cz/) that contains information about PCI devices at build time, if not already present. Enabled by default.
 - `BUILD_LAGOM`: builds [Lagom](../Meta/Lagom/ReadMe.md), which makes various SerenityOS libraries and programs available on the host system.
-- `PRECOMPILE_COMMON_HEADERS`: precompiles some common headers to speedup compilation.
 - `ENABLE_KERNEL_LTO`: builds the kernel with link-time optimization.
 - `INCLUDE_WASM_SPEC_TESTS`: downloads and includes the WebAssembly spec testsuite tests
 - `BUILD_<component>`: builds the specified component, e.g. `BUILD_HEARTS` (note: must be all caps). Check the components.ini file in your build directory for a list of available components. Make sure to run `ninja clean` and `rm -rf Build/i686/Root` after disabling components. These options can be easily configured by using the `ConfigureComponents` utility. See the [Component Configuration](#component-configuration) section below.
