+###Debian 10
+1. Update system packages (optional but recommended):  
+   `sudo apt update && sudo apt upgrade -y`
+2. Install required tools and libraries:  
+   `sudo apt install -y unzip perl libperl-dev liblwp-protocol-https-perl libfile-copy-recursive-perl libmarc-record-perl libxml-libxml-perl libxml-xpath-perl libdatetime-format-iso8601-perl cpanminus && sudo cpanm Archive::BagIt`
+3. Download the latest [Release](https://git.slub-dresden.de/digital-preservation/SLUB_SIP_Builder/-/releases):  
+   → ZIP file like `SLUB_SIP_Builder.version-XYZ-master.zip`
+4. Extract the ZIP archive and change into the project directory:  
+   `unzip SLUB_SIP_Builder.version-XYZ-master.zip`  
+   `cd SLUB_SIP_Builder`
+5. Run SLUB SIP Builder:  
+   → Try an example command from below  
+   `perl bin/slubsipbuilderbagit.pl`...
+
+###Windows 10
+1. Check UTF-8 flag at [ENG] `Systemadministration/TimeAndRegion/Region/Administration/AreaPattern` or [DE] `Systemsteuerung/Zeit und Region/Region/Verwaltung/Gebietsschema ändern/`, for using such characters as `äöüÄÖÜß`. Computer will be restarted!
+2. Download strawberry perl environment [strawberry-perl-5.30.3.1-64bit-portable](https://strawberryperl.com/releases.html)
