 ## Building in Decentraland
 
-Today, two ways of building in Decentraland exist: you either can use the [official builder](https://builder.decentraland.org) which does not require programming skills or you can use the SDK like I do in the projects mentioned above. Decentraland documentation explaining key concepts and prgrammable SDK can be found on the [Decentraland documentation site](https://docs.decentraland.org). For the SDK it is beneficial to have some software development experience but you can also jump right into it by learning [TypeScript](https://www.typescriptlang.org/), its programming language, which is relatively easy to get familiar with. The TypeScript language site offers tutorials and samples and can be used as starting point. Further useful skills include the usage of 3D modeling software being capable of exporting [glTF 2.0](https://www.khronos.org/gltf/) models, e.g. Blender to name an open source one.

 The best way to learn how-to build is taking **Carl Fravel's Decentraland University VR Academy course "Building in Decentraland"**. The course took place Aug-Sep 2019 but you can access its recorded lessons on the [Decentraland University Youtube channel](https://www.youtube.com/playlist?list=PLrON4JHIuqpkNeeUCMOnDCdZ53S6o3Ndw) and its [course materials on Google](https://docs.google.com/document/d/1AF9l3lYzQsiwFcIexGKP3TI-FFUcMVE34Su6U7FuhZo). [Carl](https://gitlab.com/cfravel) is one of the founders of Decentraland University and a member of its board and faculty.  
 
-The course is a well-paced walk through Decentraland technologies, useful building tools, the SDK itself and working with 3D modelling software like Blender to create glTF models for Decentraland. It peppered with lots of tips and tricks. You may want to join the [Decentraland University Discord](https://discord.gg/UK6AZCd) for further inquiries.
