 # DeHaze
 
 Port the Haze Explr API to GEOJSON for use in GIS applications.
+
+This was a quick and dirty project, and will probably get some updates slowly in the future. I put what I learned from this in the [HacDC Wiki](https://wiki.hacdc.org/en/Projects/API/HazeExplr).
+
+## Usage
+
+```bash
+npm i
+node serve.js
+```
+
+To use the endpoint, replace 'EMAIL' and 'PASSWORD' with your Haze Explr account details:
+
+```bash
+echo "EMAIL:`echo 'PASSWORD' | sha256sum | sed -e 's/  -//'`" | base64
+```
+
+Then, make a request to the endpoint with the resulting string as the value of the `auth` query parameter:
+
+```bash
+curl "http://localhost:3000/locations?auth=BASE64_ENCODED_STRING"
+```
+
+
+`basicauth_serve.js` does the same thing bus expects account details to be passed via basic HTTP auth, but does not work with QGIS.
