 # Description
 `robocode-svm` is a script to demonstrate Support Vector Machine (SVM) classification on outcomes of the battles of Robocode.
+
+# Installation
+The script runs under Linux and requires `robocode`, `svm-scale`, `svm-train` and `svm-predict` executables located in the `PATH`. On Arch Linux (or it's derivative, like i.e. Manjaro), this can be achieved by installing [libsvm](https://aur.archlinux.org/packages/libsvm/) and [robocode](https://aur.archlinux.org/packages/robocode/) from AUR (if enabled) by following command (or equivalent)
+```
+yaourt -S robocode libsvm
+```
+
+# Usage
+Generate the data required for SVM classification and show the accuracy
+of the generated SVM model. If coordinates are supported, one visual battle
+is shown to support the prediction.
+
+USAGE: robocode-svm ACTION
+USAGE: robocode-svm --battle x y [alpha]
+
+     --battle		Shows visual run of the specified battle
+  -g,--generate		Just generate the battle data
+  -a,--accuracy		Show the accuracy of the SVM model,
+  -c,--clean		Delete all the battle data!
+  -h,--help		Show this help
+
