+======
+
+# About
+
+An interface to libSVM from Julia
+
+# Installation
+
+* Go into `deps`
+* Run `make`
+* Run `cp svm-train ../bin`
+* Run `cp svm-predict ../bin`
+
+# Usage
+
+    using SVM
+
+    labels = [1, -1, -1, 1, 1, -1]
+
+    features = [1.0 0.0;
+                0.0 -1.0;
+                0.0 -0.9;
+                0.9 0.1;
+                1.0 1.0;
+                -1.0 -1.0;]
+
+    model = svm(labels, features)
+
+    predictions = predict(model, features)
+
+# To Do
+
+* Use binary interface to libSVM instead of libSVM text format
+* Convert sparse matrices to libSVM format
+* Restore `Makefile.win` and `windows` in `deps`
+* Allow users to configure SVM model fitting process
