+### Hashing API token
+
+`NIGHTSCOUT_API_TOKEN` must be a SHA1 hash of an Access Token from Nightscout (_Add new subject_ first in Nightscout's _Admin Tools_ if required), e.g. your Access Token for a subject named _LibreLinkUp_ might be `librelinku-123456789abcde`.
+
+Obtain your hash with
+
+```shell
+echo -n "librelinku-123456789abcde" | sha1sum | cut -d ' ' -f 1
+```
+(use `shasum` instead of `sha1sum` on Mac)
+
+which will print the hash (40 characters in length):
+```
+14c779d01a34ad1337ab59c2168e31b141eb2de6
+```
+
+You might also use an online tool to generate your hash, e.g. https://codebeautify.org/sha1-hash-generator
