## Getting Started
Inside the TutorialsCS solution, you will find several projects, each of which is a step from a hello world to a nearly full-featured communication app using the Linphone SDK.
Each step builds upon the previous ones but is standalone and can be run on its own. At each step, only new Linphone-related code is explained.
You will find additional Readme files in each project for further details.
- [00_HelloWorld](00_HelloWorld/) : A simple "Hello World" to display the Linphone version number.
- [01_AccountLogin](01_AccountLogin/) : Learn how to login to your SIP account.
