 Overview
 ========
-The library is designed to support different algorithms. Currently, only the algorithms from Walker (with the runtime improvements from Buchheim) and Fruchterman&Reingold (for small graphs) have been implemented.

+Layouts
+======
+### Tree
+Uses Walker's algorithm with Buchheim's runtime improvements (`BuchheimWalkerAlgorithm` class). Supports different orientations. All you have to do is using the `BuchheimWalkerConfiguration.Builder.setOrientation(int)` with either `ORIENTATION_LEFT_RIGHT`, `ORIENTATION_RIGHT_LEFT`, `ORIENTATION_TOP_BOTTOM` and
+`ORIENTATION_BOTTOM_TOP` (default). Furthermore parameters like sibling-, level-, subtree separation can be set.
+### Directed graph
+Directed graph drawing by simulating attraction/repulsion forces. For this the algorithm by Fruchterman and Reingold (`FruchtermanReingoldAlgorithm` class) was implemented (currently works only for small graphs).
+### Layered graph
+Algorithm from Sugiyama et al. for drawing multilayer graphs, taking advantage of the hierarchical structure of the graph (`SugiyamaAlgorithm` class). You can also set the parameters for node and level separation using the `SugiyamaConfiguration.Builder`.
