+# Identify
+
+This task iterates through your Scenes and attempts to identify the scene using a selection of scraping sources.
+
+This task accepts one or more scraper sources. Valid scraper sources for the Identify task are stash-box instances, and scene scrapers which support scraping via Scene Fragment. The order of the sources may be rearranged.
+
+For each Scene, the Identify task iterates through the scraper sources, in the order provided, and tries to identify the scene using each source. If a result is found in a source, then the Scene is updated, and no further sources are checked for that scene.
+
+## Options
+
+The following options can be set:
+
+| Option | Description |
+|--------|-------------|
+| Include male performers | If false, then male performers will not be created or set on scenes. |
+| Set cover images | If false, then scene cover images will not be modified. |
+| Set organised flag | If true, the organised flag is set to true when a scene is organised. |
+
+Field specific options may be set as well. Each field may have a Strategy. The behaviour for each strategy value is as follows:
+
+| Strategy | Description |
+|----------|-------------|
+| Ignore | Not set. |
+| Overwrite | Overwrite existing value. |
+| Merge (*default*) | For multi-value fields, adds to existing values. For single-value fields, only sets if not already set. |
+
+For Studio, Performers and Tags, an option is also available to Create Missing objects. This is false by default. When true, if a Studio/Performer/Tag is included during the identification process and does not exist in the system, then it will be created.
+
+Default Options are applied to all sources unless overridden in specific source options. 
+
+The result of the identification process for each scene is output to the log.
