 ========
-`repology` is a command line interface for Repology.org.
-It is primarily designed for

+`repology` is a command line interface for
+[Repology.org](https://repology.org/)
+written in
 [D](https://dlang.org/).
 
+`repology` will attempt to autodetect your operating system for
+selecting a repository when `--repo` is not specified. This
+autodetection works for the BSDs, macOS, and Windows.
+
 Building
 --------
-If you are using
-[DMD](https://wiki.dlang.org/DMD):
 ```sh
+$ ./configure
 $ make
 $ sudo make install
 ```
 
-If you are using
-[LDC](https://wiki.dlang.org/LDC):
-```sh
-$ make DMD=ldmd2
-$ sudo make install
-```
-
-If you are using
-[GDC](https://wiki.dlang.org/GDC):
-```sh
-$ make DMD=gdc DFLAGS='-O2 -pipe -frelease -finline -o repology'
-$ sudo make install
-```
-
 Usage examples
