+####################
+ Visual Studio Code
+####################
+
+.. note::
+
+   These instructions have been tested on Linux. macOS should mostly work the same. For Windows,
+   ymmv.
+
+An IDE can make navigating large code bases tremendously easier. Visual Studio Code is a popular and
+free IDE that is well-suited for C development. It contains syntax highlighting, navigation,
+auto-completion and a debugger. Check the `official website <https://code.visualstudio.com/>`__ for
+installation instructions.
+
+.. note::
+
+   The ``settings.json`` file referenced below can be opened in the Settings page by pressing the
+   "Open Settings (JSON)" button in the top right corner. Most of these settings can also be
+   adjusted through the GUI.
+
+*****************
+ C/C++ extension
+*****************
+
+The `C/C++ extension`_ provides most of the features we'll need to php-src development. You can find
+it in the extensions marketplace. You will also need ``gcc`` or ``clang`` installed. The extension
+will mostly work out of the box, but it is advisable to use the ``compile_commands.json`` file. It
+contains a list of all compiled files, along with the commands used to compile them. It provides the
+extension with the necessary information about include paths and other compiler flags.
+
+.. _c/c++ extension: https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools
+
+To generate the ``compile_commands.json`` file, you can use the compiledb_ tool. Install it using
+``pip``, and then prefix your ``make`` command accordingly:
+
+.. _compiledb: https://github.com/nickdiego/compiledb
+
+.. code:: bash
+
+   # Install compiledb
+   pip install compiledb
+   # Compile php-src and generate compile_commands.json
+   compiledb make -j8
+
+To tell the C/C++ extension to use the ``compile_commands.json`` file, add the following to your
+``settings.json`` file:
+
+.. code:: json
+
+   {
+       "C_Cpp.default.compileCommands": "${workspaceFolder}/compile_commands.json"
+   }
+
+********
+ clangd
+********
+
+The C/C++ extension usually works well enough. Some people find that ``clangd`` works better.
+``clangd`` is a language server built on-top of the ``clang`` compiler. It only provides navigation
+and code completion but no syntax highlighting and no debugger. As such, it should be used in
+conjunction with the C/C++ extension. For the two extensions not to clash, add the following to your
+``settings.json`` file:
+
+.. code:: json
+
+   {
+       "C_Cpp.intelliSenseEngine": "disabled"
+   }
+
+Follow the `official installation instructions for clangd
+<https://clangd.llvm.org/installation.html>`__, and then install the `clangd extension`_.
+Alternatively, you can let the extension install ``clangd`` for you. ``clangd`` requires a
+``compile_commands.json`` file, so make sure to follow the instructions from the previous section.
+By default, ``clangd`` will auto-include header files. php-src headers are somewhat peculiar, so you
+might want to disable this option in your ``settings.json`` file:
+
+.. _clangd extension: https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.vscode-clangd
+
+.. code:: json
+
+   {
+       "clangd.arguments": [
+           "-header-insertion=never"
+       ]
+   }
+
+*****
+ gdb
+*****
+
+The C/C++ extension provides the ability to use Visual Studio Code as a frontend for ``gdb``. Of
+course, you will need ``gdb`` installed on your system. Copy the following into your projects
+``.vscode/launch.json`` file:
+
+.. code:: json
+
+   {
+       "version": "0.2.0",
+       "configurations": [
+           {
+               "name": "(gdb) Launch",
+               "type": "cppdbg",
+               "request": "launch",
+               "program": "${workspaceFolder}/sapi/cli/php",
+               "args": [
+                   // Any options you want to test with
+                   // "-dopcache.enable_cli=1",
+                   "${relativeFile}",
+               ],
+               "stopAtEntry": false,
+               "cwd": "${workspaceFolder}",
+               // Useful if you build with --enable-address-sanitizer
+               "environment": [
+                   { "name": "USE_ZEND_ALLOC", "value": "0" },
+                   { "name": "USE_TRACKED_ALLOC", "value": "1" },
+                   { "name": "LSAN_OPTIONS", "value": "detect_leaks=0" },
+               ],
+               "externalConsole": false,
+               "MIMode": "gdb",
+               "setupCommands": [
+                   { "text": "source ${workspaceFolder}/.gdbinit" },
+               ]
+           }
+       ]
+   }
+
+Set any breakpoint, open a ``php`` (or ``phpt``) file and start debugging from the "Run and Debug"
+tab in the sidebar.
+
+..
+   _todo: lldb should work mostly the same, I believe. It's available by default on macOS, and as such might be more convenient.
