+# Nix package for GNUnet development
+#
+## INSTALL
+#
+# To build and install the package in the user environment, use:
+#
+# $ nix-env -f . -i
+#
+## BUILD ONLY
+#
+# To build the package and add it to the nix store, use:
+#
+# $ nix-build
+#
+## SHELL
+#
+# To launch a shell with all dependencies installed in the environment, use one of the following:
+#    $ nix-shell
+#
+# After entering nix-shell, build it:
+#
+# $ configurePhase
+# $ buildPhase
+#
+## NIXPKGS
+#
+# For all of the above commands, nixpkgs to use can be set the following way:
+#
+# a) by default it uses nixpkgs pinned to a known working version
+#
+# b) use nixpkgs from the system:
+#    --arg pkgs 0
+#
+# c) use nixpkgs at a given path
+#    --arg pkgs /path/to/nixpkgs
+#
+## CCACHE
+#
+# To enable ccache, use the following:
+#
+#    --argstr ccache_dir /var/cache/ccache
+
+# or when using nix-shell:
+#    --argstr ccache_dir ~/.ccache
+#
+# and make sure the given directory is writable by the nixpkgs group when using nix-build or nix-env -i,
+# or the current user when using nix-shell
+#
+
