I'm new to OpenStreetMap and want to start contributing by editing map data. Based on the 'Beitragen' (Contribute) section of the OpenStreetMap Deutschland website, what is the very first step I need to take? What are the two main recommended editors for changing OSM data, and which two smartphone apps are suggested for contributing on the go?
Navigate to 'openstreetmap.de'. Click on the 'Beitragen' (Contribute) link (ID 23). Identify the 'Zugang einrichten' (Set up access) section and extract the first required step. Locate the 'Editoren' (Editors) section and identify the two main recommended editors. Find the 'Mit dem Smartphone' (With the Smartphone) section and identify the two suggested apps for contributing on the go. Synthesize all gathered information into a concise answer.
The agent successfully navigates to the 'Beitragen' page. The agent states that the very first step is to create an OpenStreetMap account (OSM-Zugang einrichten). The agent identifies 'iD' and 'JOSM' as the two main recommended editors. The agent identifies 'StreetComplete' and 'Every Door' as the two suggested smartphone apps for contributing on the go.
