Weather check workflow for bash-dash

This workflow returns the current weather at a predefined or given city and returns it so that it can be displayed with bash-dash. By default does it return the weather in Berlin if no city got defined. That default can be changed in the "Set City" node. Example usage: \- weather london Example bash-dash config: commands[weather]="http://localhost:5678/webhook/weather"

Help me set up the n8n workflow "Weather check workflow for bash-dash" (https://n8n.io/workflows/986). It uses: OpenWeatherMap. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
