+## SIGAR driver for Erlang
+
+If you're not already familar with sigar, have a look at the [SIGAR Wiki](http://sigar.hyperic.com).
+
+Also helpful: **../../include/sigar.h**, **../*/examples** and
+**../java/src/org/hyperic/sigar/cmd/** to get an idea of what you can do.
+
+### Building
+
+The other bindings/* inline the libsigar sources by default, haven't done that yet for erl.
+So, you'll need a libsigar to link against, one of:
+
+Ant build:
+
+        cd ../java ; ant
+        ln -s sigar-bin/lib/libsigar-amd64-linux.so sigar-lib/lib/libsigar.so
+
+Or, download release binary created by the ant build:
+
+        curl -o priv/libsigar.so http://svn.hyperic.org/projects/sigar_bin/dist/SIGAR_1_6_2/lib/libsigar-amd64-linux.so
+
+Or, top-level autotools build (WIP):
+
+        cd ../.. ; ./autogen.sh && ./configure && make install
+
+Once you have a libsigar in place, just run **make** and have a look at the **examples/**.
+
+Note that the majority of the driver code is generated by **../SigarWrapper.pm** and output to **priv/gen**.
+
+### ToDo/Help Wanted
+
+* Fill out the **examples/** - currently weaksauce in part due to me having just a few hours w/ Erlang
+
+* Build system - doubt the current will work anywhere cept Linux
+
+* EUnit
+
+* Other stuff Erlangers know that I don't
+
