## Step by step configuration

As an example, we'll be looking at the Palo-Alto-sha256 feed. This feed will ingest indicators of type File. These are the feed instance configuration parameters for our example

**Indicator Type** - File.
**Server URL**: <https://digitalwitness.zeroday.live/exports/download/Palo-Alto-sha256.csv>.
**Credentials** - user: *XXX*, password: *XXX* - need to be obtained from Zero Day Live portal.

The other paramer values can stay with defualt

**Field Names** - There is only single field and that field is the indicator to fetch. So to confgiure that we can leave default `value` as is.
