+cdist-type__wikijs(7)
+========================
+
+NAME
+----
+cdist-type__wikijs - Deploy the wiki.js software.
+
+DESCRIPTION
+-----------
+
+See wiki.js.org for more information. This type deploys with a postgresql
+database, since it is the upstream recommended for production, and they seem to
+strongly suggest that in the next releases, they will not support anything else.
+
+Currently, this type servers wikijs as standalone, listening on ports 80 and
+443, and with a service file for OpenRC. Feel free to contribute a
+generalisation if you require one.
+
+REQUIRED PARAMETERS
+-------------------
+
+database-password
+  The password to the PSQL database.
+
+version
+  'wikijs' version to be deployed.
+
+OPTIONAL PARAMETERS
+-------------------
+
+database
+  The name of the PSQL database to connect to. If omitted, then 'wikijs' is
+  used.
+
+database-user
+  The name of the PSQL database user to connec as. If omitted, then 'wikijs' is
+  used.
+
+letsencrypt-mail
+  If the SSL parameter is passed, then we setup wikijs to automatically obtain
+  certificates: this is the email used to sign up to a LE account.
+
+http-port
+  Specify HTTP port, defaults to 80.
+
+http-port
+  Specify HTTPS port, defaults to 443. Only relevant if the SSL flag is enabled.
+
+BOOLEAN PARAMETERS
+------------------
+
+ssl
+  Whether or not to enable the wikijs automatic obtention of LE certificates.
