+## General info
+
+The program performs RANSAC circle detection.
+Given [a set of points that approximately form a circle](https://relate.cs.illinois.edu/course/cs357-f15/file-version/03473f64afb954c74c02e8988f518de3eddf49a4/media/newton2/CircleFit.html),
+using [RANSAC algorithm](https://youtu.be/nG5QC_WFdGU),
+a center and a radius of the circle is detected.
+
+## Technologies
+
+* python = 3.6
+* matplotlib = 3.1
+* numpy = 1.17
