How to help
Help First Responders with the Nepal Earthquake: Volunteer for Humanitarian Open StreetMap
It doesn't matter how long you work, or how many features you digitize. There are currently hundreds of people mapping on HOTOSM for the Nepal earthquake.
This will take you about 30 minutes. It's self-directed so you can go back and re-watch the videos (or re-read the directions) as many times as you need to. Create an account and check the PUBLIC DOMAIN BOX.
Pick a project that is appropriate for your skill level, and read the directions carefully for the job. Select one of the squares next to one that is marked as complete. This will allow you to pan to the completed square so you can see how others are digitizing the features and mimic their work. Go to the Contribute tab, and "Start Mapping" (if you're not sure which editor to use, try iD editor). When you're done, "Unlock" the square you were in.
If you are a responder, or working with any organization that needs the most up-to-date geodata for the region, a consulting company called Geofabrik has set up a download site for OSM data that will be updated every 30 minutes throughout the HOTOSM activation. Find the data in various formats (including Garmin, Shapefile, etc...) here.
