 # Continuous-CBS
 Continuous CBS - a modification of conflict based search algorithm, that allows to perform actions of any arbitrary duration.
-The main differences are the representation of constraints, timeline, collision detection mechanism and using SIPP algorithm as a low-level planner. More info about CCBS and its principles of work you can find at https://arxiv.org/abs/1901.05506

 The master-version can work both on grids and roadmaps and supports the following enhancements:
 - Disjoint Splitting
 - Prioritizing conflicts
 - High-level heuristics
 
-The detailed descriptions of these enhancements can be found at https://arxiv.org/abs/2101.09723

+## Content
+
+Besides the source code of the algorithm, there are also some usefull folders:
+* [Demos](https://github.com/PathPlanning/Continuous-CBS/tree/master/Demos) - contains a few visualized demonstrations of the plans created by CCBS.
+* [Examples](https://github.com/PathPlanning/Continuous-CBS/tree/master/Examples) - contains the exmaples of input/output XML-files required/provided by the algorithm.
+* [Instances](https://github.com/PathPlanning/Continuous-CBS/tree/master/Instances) - contains the archives with the maps and instances in the required format, that were used for the experimental evaluation in the papers about CCBS.
+* [ExpResults](https://github.com/PathPlanning/Continuous-CBS/tree/master/ExpResults) - contains the raw data of the results obtained during the experimental evaluation of CCBS algorithm.
+* [Releases](https://github.com/PathPlanning/Continuous-CBS/releases) - not a folder, but the tagged commits that were used to get the results for the corresponding papers.
