 ## Configuration
 
-To be compatible with `./Meta/ladybird.sh`, we must set CC and CXX to the correct compilers for *both* configure and build. This can be done in the `.vscode/settings.json` file.
-
-```json
-{
-  "cmake.configureEnvironment": {
-    "CC": "clang-18",
-    "CXX": "clang++-18"
-  },
-  "cmake.buildEnvironment": {
-    "CC": "clang-18",
-    "CXX": "clang++-18"
-  },
-  "clangd.path": "clangd-18"
-}

 Run `./Meta/ladybird.sh build` at least once to kick off downloading and building vcpkg dependencies.
 
 The CMake Tools plugin should automatically detect the `CMakePresets.json` at the root of the repository.
 Selecting and activating the `default` preset should be enough to get started after the initial build.
 You can also use the `Debug` preset to build with debug symbols, or the `Sanitizer` preset to build with ASAN/UBSAN.
 
-If building through VsCode itself causes vcpkg to rebuild the world, verify that the environment settings match the `CMAKE_CXX_COMPILER` line in the build directory's `CMakeCache.txt`.

 For additional settings recommendations, see the [Settings](#settings) section below.
