 # MapServer
 
+## Build
+
+```bash
+docker build -t gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-web-viewer/mapserver:latest mapserver/
+```
+
 ## Usage
 
 ```bash
-docker run -p 8888:80 -d --rm --name cspp-geo-mapserver -v cspp-geo-abi-l1b-geotiffs:/data gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-web-viewer/mapserver:latest
+docker run -p 8888:80 -d --rm --name cspp-geo-mapserver --network cspp-geo-rabbit -v cspp-geo-abi-l1b-geotiffs:/data gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-web-viewer/mapserver:latest
 ```
 
 Then the main mapserv CGI script can be accessed with:
 
 http://localhost:8888/cgi-bin/mapserv
 
+where MapServer parameters can be appended to the end (after a `?`). However,
+an easier to access API is available:
+
+```bash
+http://localhost:8888/wms/<satellite>/<instrument>/<sector>/<data_level>?...
+```
+
+An example URL of this including MapServer parameters is:
+
+```bash
+http://localhost:8888/wms/g16/abi/radf/l1b?request=GetMap&service=WMS&version=1.1.1&srs=EPSG:930916&layers=true_color_test&bbox=-5000000,-5000000,5000000,5000000&format=image/png&WIDTH=1000&HEIGHT=1000&TIME=2020-01-21T16:00:16
+```
