 ## 2. Getting Started
 
+### Prerequisite : Git LF/CRLF configuration (for Windows users)
+
+By default, Git on Windows may convert line endings (LF → CRLF). The whole IroCO2 project was configured to work with LF end-of-line. To avoid unwanted conversions, run one of the following:  
+  
+```bash  
+git config --system core.autocrlf false  # per-system
+git config --global core.autocrlf false  # per-user
+git config --local core.autocrlf false   # per-project
+```
+
