 ## Build
 Install java, maven and, if on windows, git-bash
 
-First, install dependencies into local maven repository:
-
-```bash
-mvn install:install-file -Dfile=lib/HexLib.jar -DgroupId=at.HexLib -DartifactId=HexLib -Dversion=0.0.0 -Dpackaging=jar -DlocalRepositoryPath=./lib
-```
-
-Then build project as usual:
+Run in console:
 
 ```bash
 mvn install
 ```
 
-If you got error:
-```bash
-[WARNING] The POM for kaitai_struct_visualizer_java:HexLib:jar:0.0.0 is missing, no dependency information available
-```
-it means, that you already tried to build project without success and maven cache
-unsuccessful state of dependency resolution. Just add switch `-U` to maven invocation
-to force maven re-check dependencies:
-
-```bash
-$ mvn -U install
-```
