-## Other compilers
-
-Besides the DMD reference compiler which uses its own backend, there are
-two other compilers that can be fetched through the
-[dlang.org](https://dlang.org) download section:
-
-* [**GDC**](http://gdcproject.org/downloads) which uses the GCC backend
-* [**LDC**](https://github.com/ldc-developers/ldc#installation) based on the LLVM backend
-
-GDC and LDC aren't always at the most recent DMD frontend's versions,
-but provide better optimization levels as well as support
-for other platforms like e.g. ARM.
-
-See the wiki for [more information](https://wiki.dlang.org/Compilers)
+The D language reference compiler is called DMD (Digital Mars D).
+Also available are [LDC](https://github.com/ldc-developers/ldc)
+(a [LLVM](http://llvm.org)-based D compiler).
+and [GDC](https://gdcproject.org) (a [GCC](https://gcc.gnu.org/)-based D
+compiler).
+See [the Compilers wiki page](https://wiki.dlang.org/Compilers) for
+more detailed information, but if you're new to D and aren't sure
+which to install, install DMD.
+
+## Download and Install
+
+The [D downloads page](https://dlang.org/download.html) provides an
+overview of the various D implementations, and contains links to
+pre-built OS-specific DMD packages ready to download and install.
+
+As an alternative to the OS-specific packages, there's also an
+[install script](https://dlang.org/install.html)
+for use with any Posix-like System (Linux, FreeBSD, MacOS)
+that can install the various implementations (including multiple versions of them)
+locally without requiring any administration rights.
+See the [install script documentation](https://dlang.org/install.html) for details.
