+# Universal Git Analyzer V10 — запуск кликом
+
+## Ubuntu / Linux
+Двойной клик по `run_linux.sh` или запуск:
+
+```bash
+./run_linux.sh
+```
+
+Если не запускается:

+
+Нужно, чтобы на Windows были установлены:
+- Python 3
+- Git for Windows
+
+## Настоящий `.exe` для Windows
+На Windows запусти двойным кликом:
+
+```text
+build_windows_exe.bat
+```
+
+После сборки файл будет здесь:
+
+```text
+dist\UniversalGitAnalyzer.exe
