# `invalid-systemd-documentation`

The named systemd service file contains a `Documentation` field that is not a URI.

The field should contain a space-separated list of URIs referencing documentation for the unit or its configuration. Accepted are only URIs of the types `http://`, `https://`, `file:`, `info:`, `man:`.

For more information about the syntax of these URIs, see `uri(7)`. The URIs should be listed in order of relevance, starting with the most relevant. It is a good idea to first reference documentation that explains what the unit's purpose is, followed by how it is configured, followed by any other related documentation.

The `Documentation` key may be specified more than once, in which case the specified list of URIs is merged. If the empty string is assigned to this option, the list is reset and prior assignments have no effect.

Documentation for systemd service files can be automatically viewed using `systemctl help servicename` if this field is present.

Severity: | `info`
Experimental: | `false`
