 *Important*: The second script, noaa-cdo-station-list-all, requires an access token.
 This can be obtained for no cost from https://www.ncdc.noaa.gov/cdo-web/webservices/v2.
 Once obtained, this token should be placed in a text file named, .noaa_rc, in
 the current working directory or your home directory.
 Like:
 ```shell script
-CDO_TOKEN=[your token]
+CDO_TOKEN=sometoken
+```
+
+You can do it as a one-liner:
+```shell script
+echo "CDO_TOKEN=sometoken" > ~/.noaa_rc
 ```
 
 Execution of these scripts requires the following programs to be present in your
