Shell dependency

Do we need to call out the dependency on `bash`? For example, this doesn't work in `fish`:

```
$ statements=$(< src/statements.sql) && \
echo '{"ksql":"'$statements'", "streamsProperties": {}}' | \
curl -X "POST" "http://localhost:8088/ksql" \
-H "Content-Type: application/vnd.ksql.v1+json; charset=utf-8" \
-d @- | \
jq
fish: Unsupported use of '&&'. In fish, please use 'COMMAND; and COMMAND'.
statements=$(< src/statements.sql) && \
^
```

Or is it sufficient to consider that any dev using a weird shell will be sufficiently aware of stuff like this?
