# Bulk Concept Creation

First, you have to choose a template in order to bulk create specific concepts. Navigate to the main toolbar and select `File > New… > Concepts from template (bulk)` and hit **`Next`**.

On the following page of the wizard dialog, you can choose from the pre-imported templates (all currently existing [SNOMED International templates](https://github.com/IHTSDO/snomed-templates) are available), which will determine the concepts to be created.

Now you can choose the bulk input file which must contain values for all slots present in the selected template definition. For example, the template called "*Congenital \[morphology] of \[body structure] (disorder)*" has the following template definition (written in [Expression Template Language v1.0](https://confluence.ihtsdotools.org/display/DOCSTS/6.1.+Expression+Template+Language)):

```
64572001 |Disease (disorder)|:
 {
  246454002 |Occurrence (attribute)| = 255399007 |Congenital (qualifier value)|,
  116676008 |Associated morphology (attribute)| = [[+id(<< 49755003 |Morphologically abnormal structure (morphologic abnormality)|) @morphology]],
  363698007 |Finding site (attribute)| = [[+id(<<442083009 |Anatomical or acquired body structure (body structure)|) @findingSite]]
 }
```

For this template, one must create a tab or comma-separated input file with the following two columns: *morphology*, *findingSite*. Then each individual row must represent a potential concept replacement value.

If the template definition selected is valid, syntactically correct and the format of the bulk input file is in correspondence with the template, the bulk creation of concepts starts after hitting **`Next`**. When the process finished, a wizard dialog can be opened by double-clicking on the finished remote job, which will display all the concepts with their IDs and FSNs that have been newly created and added to SNOMED CT.

Created concepts can be opened from the task **Review Changes Tab.**
