+# Services
+
+---
+
+The application includes three services: two Axios-based and one internal. Axios is a tool for handling HTTP requests efficiently.
+
+1. AxiosInstance Service:
+   - This service is used for the old API and supports all paths that require the use of the old API
+2. AxiosInstanceNewAPI Service:
+   - This service is used for the new API and works in the same way as the previous one
+3. PluginsManager Service:
+   - It is an internal service that handles the communication between the application-plugin
