+The Data Preprocessing Pipeline transorms raw OpenStreetMap (OSM) data into optimized routing graphs that can be efficiently queried by OSRM's routing engine.
+
+# Data Preprocessing Pipeline Overview
+The pipeline supports two algorithmic approaches:
+
+**Contraction Hierarchies (CH):** Uses **`osrm-extract`**, **`osrm-contract`** for graph contraction.
+
+**Multi-Level Dijkstra (MLD):** Uses **`osrm-extract`**, **`osrm-partition`** followed by **`osrm-customize`**
+
+For our case we're using **Contraction Hierarchies**, So we extract `*.osm` by executing these commands:
