+These tutorials can be followed instead of the original t8code tutorials. They explain working with t8code with the help of the

+Please note, that the mesh handle tutorials start at step 2, because the first 2 steps are the same as in the original tutorials. Please complete these first and then come back to the [Mesh Handle Tutorial Overview](../tutorials/mesh_handle/README.md)

+# Mesh handle tutorials
+
+This is the tutorial collection for the [mesh_handle](../mesh_handle/README.md) interface of `t8code`. 
+
+The `mesh handle` Interface acts as a bridge between the user and the original t8code library. When using the mesh handle, t8code acts as if it is working with usual unstructured meshes. 
+For more information about the [mesh_handle](../mesh_handle/README.md), look into the readme there.  
+
+There are corresponding articles for every tutorial in this folder in the [Wiki](https://github.com/DLR-AMR/t8code/wiki/Tutorial---Overview). The article can be used as a step-by-step guide for each tutorial. 
+
+Please note, that the mesh handle tutorials start at step 2. This is due to the fact, that [step0](https://github.com/DLR-AMR/t8code/wiki/Step-0---Hello-World) and [step1](https://github.com/DLR-AMR/t8code/wiki/Step-1---Creating-a-coarse-mesh) are the same when using the mesh handle so please use the original `t8code` tutorials for these steps. 
+
+## General
+
+[step0](https://github.com/DLR-AMR/t8code/wiki/Step-0---Hello-World) - 
+Initialize t8code and print a welcome message. (This links leads to the original t8code tutorials, come back after Step 1 to use the mesh handle tutorials instead.)
+
+[step1](https://github.com/DLR-AMR/t8code/wiki/Step-1---Creating-a-coarse-mesh) - 
+Create a coarse mesh, output it to vtu and destroy it. (This links leads to the original t8code tutorials, come back after this step to use the mesh handle tutorials instead.)
+
+[step2] -  
+Create a uniform mesh, get its number of local and global elements, output it to vtu and destroy it.
+
+[step3] - 
+Adapt a mesh according to a user defined criterion. 
+
+[step4] - 
+Partitioning, balancing and creating a ghost layer for a mesh. Explains the mesh creation process in more detail.
+
+[step5](mesh_handle/t8_mesh_element_data.cxx) - 
+Associating user data with the elements of a mesh. Exchanging ghost values for element user data. Writing element user data to vtu.
+
+[step6] - 
+Going into more detail about mesh handle competence packs. Explaining element data competences and caching. Creating a custom competence.
