-### Prepare the MATSim input files
-1. Switch to the branch `prepare`. (Currently, the preparation requires an older MATSim version than the railsim contribution. So, we can't have everything in one branch. So, for now, we have to deal with two different branches.)

+### Prepare the input files
+
+##### Step 1: Get the required original data
+
+1. Download the GTFS file, e.g., from https://opentransportdata.swiss/en/group/timetables-gtfs.
+1. Download the OSM file, e.g., from https://download.geofabrik.de/europe/switzerland.html.
+11. (Optional) Process the OSM data, e.g., with osmosis. Download osmosis from https://wiki.openstreetmap.org/wiki/Osmosis. Filter the OSM data, e.g. with the following command: `osmosis --rb file=switzerland-latest.osm.pbf --tf accept-ways railway=* --used-node --wx switzerland_railways.osm`
+1. Put the GTFS file (`*.zip`) and (processed) OSM file (`*.osm`) file into the `original_data` directory.
+
+##### Step 2: Read the original data and generate the MATSim input files
+
+1. Open the JAVA class `GenerateRailsimInput` located in `src/main/java/ch/sbb/prepare`.
+1. Adjust the file names and make sure the files are locally available in the `original_data` directory.
+1. Adjust some further inputs, e.g. rail product names, area of interest, ...
+1. Run the `GenerateRailsimInput` class. The preparation makes use of the pt2matsim repository, see here: <https://github.com/matsim-org/pt2matsim>
