Note that currently this project is just used to test the upload of sourcemaps and deploy notifications -- the sourcemaps are not expected to be correctly applied to errors from this project since we didn't set up the revision and assetsUrl.
## Setup
-Your API key should be in an environment variable `HONEYBADGER_API_KEY`. You can do this with [direnv](https://direnv.net/) or however you like.
+Two environment variables are required:
+1. `HONEYBADGER_API_KEY`: Your project's API key
+2. `HONEYBADGER_REVISION`: A unique string. This needs to match between your Honeybadger.configure() and the sourcemap plugin for sourcemaps to be applied.
+
+You can manage environment variables with [direnv](https://direnv.net/) or however you like.
## Testing
Run `npm run build` to run webpack. You should see a sourcemap and a deploy notification uploaded to Honeybadger.
