+## About
+
+This api works by getting releases versions via GitHub API, using link 
+`https://api.github.com/repos/[REPOSITORY AUTHOR]/[REPOSITORY NAME]/releases"`.
+
+The methods described in [Method Summary](#Method-Summary), modify the values of the variables,
+```java
+private static String version;
+private static String repositoryURL;
+```
+coded in API. This API uses jsonSimple library to work, maven dependency is in [Installation](#Installation). 
+In case of errors with API please describe it in Issues.
+
