-## How to run the compiler
-### Possibilities
-### 1. Start miniCompiler using make:
-Make needs to be installed
-```bash
-cd .\src\test\ ; make clean compile-miniCompiler
-```
-
-### 2. Start miniCompiler using jar:
-If you do not have the .jar, download it [here](https://gitea.hb.dhbw-stuttgart.de/i22005/NichtHaskell2.0/src/branch/Endabgabe/src) or compile it using mvn package or make first
-```
-java.exe -DgenJar=bool -DgenClass=bool -jar path_to_jar\jarName.jar 'path_to_input_file.java' 'path_to_output_directory'
-```
-
-Example (jar needs to be in the target directory)
-```bash
- java.exe -DgenJar=true -DgenClass=true -jar .\target\JavaCompiler-1.0-jar-with-dependencies.jar 'src/main/resources/input/CompilerInput.java' 'src/main/resources/output'
-```
-
-- set DgenJar true, to generate the jar, false for no jar
-
-```
- DgenJar=true
-```
-
-- set DgenClass true, to generate class files, false for no class files
-
-```
- DgenClass=true
- ```
-
-## How to run tests
-
-```bash
-mvn test
-```
-Or start them manually in your IDE
