+What?
+=====
+
+This is a fork of trayfreq, intended to work on modern Linux systems.
+The original trayfreq wasn't compatible with Archlinux, due to the migration away from a `/proc/acpi` directory.
+I forked the project and got it working again.
+
+If you're using ArchLinux, just jump over to the [AUR page for this software](https://aur.archlinux.org/packages/trayfreq-archlinux) and install it that way.
+
+Despite the software's name, it should work on other distros as well.
+
+
+Runtime Dependencies
+--------------------
+
+* gtk3
+* sudo
+
+Building
+========
+Due to KISS, I don't tend to use ./configure scripts for relatively small programs.
+Instead, it's up to the user to check they have the right libraries.
+The sort of parameters you might pass to a ./configure can instead be passed to make.
+
+Here's a list:
+
+* BINDIR to override default binary directory (`/usr/bin`) for trayfreq and trayfreq-set
+* PREFIX to prefix all paths with something
+* LOCALE_DIR to override default of `/usr/share/locale`
+* SUDO to override default sudo program `/usr/bin/sudo`
+* MAKE to override default make program `make`
+* CC to override default compiler `gcc`
+* TRAYFREQ_SET to override default trayfreq-set program of `PREFIX/BINDIR/trayfreq-set`
+* DESTDIR (only for `make install` -- see below)
+
+If you'd like a huge amount of debug information on the tty every time you run trayfreq or trayfreq-set, then set DEBUG to something, eg:
+
+	make all DEBUG=yeah
+
+
+Extreme example for nutty system with binaries at `/exec` and sudo `/exec/sodu`:
+
+	make all BINDIR=/exec SUDO=/exec/sodu
+
+
+Installation
+============
+A plain `make install` should work if you're installing straight to `/`, i.e. you're not building a package or anything.
+If you *are* building a package or installing to a special dir, then you might want something like this:
+
+	make install DESTDIR=/path/to/package/temp/dir
+
+This will prefix **all** paths with `/path/to/package/temp/dir` while installing.
+
+Autostarting
+------------
+`make install` will copy a .desktop file to /etc/xdg/autostart, meaning that all xdg-compliant window managers should start it automatically when Bob logs in.
+Bob's WM starts these programs as root, thus he is fully able to change the governor.
+
+Alice uses a non-xdg-compliant WM (e.g. dwm)  so trayfreq is run as the user `alice`.
+She doesn't have permission to write to the files under `/sys/` so trayfreq can't change the governor.
+Alice needs to make trayfreq run `trayfreq-set` through sudo.
+This can be done in the configuration file.
+Then, she also needs to give herself passwordless permission to run `trayfreq-set` through sudo:
+
+
+    # ... (/etc/sudoers
+	alice ALL = NOPASSWD: /usr/bin/trayfreq-set
+	# ...
+
+Simple.
+
