 ## Installation
 
+The build system is GNU Autotools, with a somewhat non-standard
+setup.
+
+The default goal `all` in `GNUmakefile` can perform the following
+sequence in one go:
+1. Run `autoconf` using `configure.ac` and `Makefile.am` as inputs.
+2. Run `configure` (generated in step 1) to produce a `Makefile`.
+3. Build and compile using the generated `Makefile`.
+
 ### Unix-like Systems (Linux, FreeBSD, macOS)
 using GNU make, `gmake` on Freebsd and macOS.
 
 ```bash
-git clone https://github.com/soppelmann/async-process.git
+git clone https://github.com/lem-project/async-process.git
 cd async-process
 make
 sudo make install
 ```
 
 The library installs to `/usr/local` by default. To install elsewhere:
 
+To install to a different destination, the `make` command should
+be substituted with another similar to the examples below, passing
+an explicitly-set `PREFIX` environment variable.
+
+```bash
+PREFIX=/your/custom/path make
+PREFIX=/usr make
+PREFIX=$HOME/.local make
+```
+
+Alternatively, you can run the Autotools toolchain sequence
+as follows, with a slightly different method of setting the
+destination prefix:
+
 ```bash
-make install PREFIX=/usr
-make install PREFIX=$HOME/.local
+autoreconf -i
+./configure --prefix=/your/custom/path
+make
+make install
 ```

 On Windows, no C compilation is required. The library uses a pure Lisp implementation via CFFI:
