 - Schreibt ein CSV‑Log (`.log` neben der Output‑PPTX)
 - Baut eine neue PPTX und zeigt eine Summary (Name, Größe vorher/nachher, Ersparnis %, Zeit)
 
-## Änderungen in 1.1.9
-- SVG Files Default Profile: `balanced` statt `aggressive`
-- Datei-Eigenschaften der neu generierten PPTX enthält Hinweis auf Compression `compressed by PPTX Image Compressor` 
+## Änderungen in 1.2.0
+- Möglichkeit mit build.bat eine pptx-image-compressor.exe zu erstellen
+- Fixes für install_and_run.bat in venv / "raw" environments
 
 ## Hinweise
 - `-t` steuert die Parallelität der Python‑Threads; intern wird `caesiumclt --threads 1` gesetzt, sobald `-t > 1`, um Oversubscription zu vermeiden. Default ist 16

+#  PPTX Image Compressor – Installation Logic
+
+## 1. Intro – One Line Summary
+
+> The script selects the best available Python environment, falls back to a self-installed embedded runtime if necessary, ensures `pip`, installs `svg-polish` when possible, and runs the application with graceful degradation.
+
+## 2. Lightweight Overview
+
+```text
+START
+│
+├─► Find usable Python
+│     ├─ venv (active / local)
+│     ├─ system Python
+│     └─ fallback: download embedded Python
+│
+├─► Ensure pip works
+│     ├─ pip exists → OK
+│     ├─ ensurepip → try fix
+│     └─ get-pip.py → fallback fix
+│
+├─► Install dependency
+│     └─ svg-polish (optional but preferred)
+│
+├─► Run main script
+│
+└─► END
+```
