+# Installing a D Compiler
+
+To run D code you first need to build it. To build it a compiler must be
+installed on the system.
+
+There are several D compilers to choose from, you can find a list of them under
+https://dlang.org/download.html
+
+## DMD
+
+DMD is the official reference compiler for D. It always implements the latest
+features and the latest standard library + runtime. Additionally it is the
+fastest compiler out of the 3, although it doesn't produce the fastest
+executables. It's a good compiler for prototyping and quick scripts and is the
+recommended compiler to get if you don't know which one to get.
+
+Download: https://dlang.org/download.html#dmd
+
+## LDC
+
+LDC is an LLVM-based (like clang) D compiler. It supports a variety of operating
+systems and target architectures and has very frequent releases, usually being
+up-to-date to the DMD reference compiler within days. It takes longer to compile
+executables but results in much better optimized executables than with DMD. LDC
+is a good compiler to be using in production to create executables.
+
+Installation (package manager): https://github.com/ldc-developers/ldc#installation
+
+Download (executables): https://github.com/ldc-developers/ldc/releases
+
+## GDC
+
+GDC is an GCC-based D compiler. Other than the other compilers it comes built-in
+into GCC and does not require a separate installation. It supports a variety of
+operating systems and target architectures. Being tied to GCC's release schedule
+it is often behind in new features but receives bug fix backports from later
+versions in minor updates. GDC could be called the most stable compiler as it is
+tied to specific D frontend versions for a while, only fixing issues without big
+changes. GDC is a good compiler to be using in production to create executables.
+
+GDC is included in GCC since GCC 9.0, installing a recent GCC version should
+have it included by default.
+
+For Linux distributions packaging the backends in different packages or Windows
+downloads see https://www.gdcproject.org/downloads
+
+---
+
+The installation packages of DMD and LDC come with various utilities (DUB, rdmd)
+installed. If you don't have these utilities because you used your Operating
+System's package manager or installed GDC, code-d will download the executables.

+# Configuring Code-D
+
+Code-D uses the standard VSCode user settings. Open the user settings and check
+out the section `Extensions > D` to view or edit all the settings.
+
+In the JSON settings editor the settings all start with `"d."` for D related
+settings, `"dfmt."` for formatter related settings and `"dscanner."` for linting
+related settings.
+
+Some features are disabled by default because they are not fully ready for all
+use-cases yet or may significantly increase resource usage on low-spec machines.
+If you want to, do give these features a try and report issues on
+[GitHub](https://github.com/Pure-D/code-d/issues).
+
+Code-D is using a language server protocol called Serve-D to implement all of
+its features. Serve-D gets more frequent updates than Code-D and these will
+automatically be downloaded whenever a new stable release gets released. If you
+don't want to receive automatic updates or want to receive more frequent beta or
+nightly updates, configure the `d.servedReleaseChannel` user setting to your
+liking and reload the window.
