+#+TITLE: Hacking whispers
+
+* Contributing
+
+By far the easiest way to hack on whispers is to develop using Guix:
+
+#+BEGIN_SRC bash
+  # Obtain the source code
+  cd /path/to/source-code
+  guix shell -Df guix.scm
+  # In the new shell, run:
+  hall build --execute && autoreconf -vif && ./configure && make check
+#+END_SRC
+
+You may also want to set your directory as an authorized directory for
+`guix shell' so it works without arguments. To do that, simply run
+
+#+BEGIN_SRC bash
+  echo $(pwd) >> $HOME/.config/guix/shell-authorized-directories
+#+END_SRC
+
+You can now hack this project's files to your heart's content, whilst
+testing them from your `guix shell' shell.
+
+To try out any scripts in the project you can now use
+
+#+BEGIN_SRC bash
+  ./pre-inst-env scripts/${script-name}
+#+END_SRC
+
+If you'd like to tidy the project again, but retain the ability to test the
+project from the commandline, simply run:
+
+#+BEGIN_SRC bash
+  ./hall clean --skip "scripts/${script-name},pre-inst-env" --execute
+#+END_SRC
+
+** Manual Installation
+
+If you do not yet use  Guix, you will have to install this project's
+dependencies manually:
+  - autoconf
+  - automake
+  - pkg-config
+  - texinfo
+  - guile-hall
+
+Once those dependencies are installed you can run:
+
+#+BEGIN_SRC bash
+  hall build -x && autoreconf -vif && ./configure && make check
+#+END_SRC
