-## Quickstart
-To run the software, simply execute
-```shell
-bash ./build_and_run_theia.sh
-```
-The shell file uses the commands below.
-
-### Adding a custom language server
-For using a language, Theia needs a language server file, it can start (typically a .jar file). The file `àssemble_custommade.sh` is
-responsible for copying a freshly compiled language server to Theia. To do so, **have a look in the file and
-configure its variables**. Afterwards, one can run:
-```shell
-bash ./assemble_custommade.sh
-```
-The language server, which is used for development is referenced [in this repository](https://github.com/rrcomtech/Visualization_of_DSL_Families).
