+### `<jira_config>`
+
+JIRA notification are sent via [JIRA Rest API v2](https://developer.atlassian.com/cloud/jira/platform/rest/v2/intro/)
+or [JIRA REST API v3](https://developer.atlassian.com/cloud/jira/platform/rest/v3/intro/#version).
+
+Both APIs have the same feature set. The difference is that V2 uses [Wiki Markup](https://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=all)
+for format the issue description and V3 uses [Atlassian Document Format (ADF)](https://developer.atlassian.com/cloud/jira/platform/apis/document/structure/).
+The default `jira.default.description` template only works with V2.
+
+```yaml
+# Whether to notify about resolved alerts.
+[ send_resolved: <boolean> | default = true ]
+
+# The incoming webhook URL.
+[ webhook_url: <secret> ]
+
+# The Atlassian Side to send Jira API requests to. API path must be included.
+# Example: https://company.atlassian.net/rest/api/2/
+[ api_url: <string> | default = global.jira_api_url ]
+[ api_username: <string> | default = global.jira_api_username ]

+[ http_config: <http_config> | default = global.http_config ]
+```
+
+#### `<custom_fields>`
+
+Jira custom field can have multiple types. Depends on the filed type, the values must be provided differently.
+
+```yaml
+fields:
+   # TextField
+   customfield_10001: "Random text"
+   # SelectList
+   customfield_10002: {"value": "red"}
+   # MultiSelect
+   customfield_10003: [{"value": "red"}, {"value": "blue"}, {"value": "green"}]
+```
+
 ### `<opsgenie_config>`
 
 OpsGenie notifications are sent via the [OpsGenie API](https://docs.opsgenie.com/docs/alert-api).
