# Configure registration parameters

> Configure registration parameters for the FlexiCapture mobile client by creating a JSON description file and naming it correctly in the project file storage.

To configure registration parameters for the FlexiCapture Mobile Client, an Administrator creates a JSON file that describes the parameters and places it in the project file storage.

<Steps>
  <Step title="Find the project ID">
    Find the ID of the FlexiCapture project that will process documents from the Mobile Client.
  </Step>

  <Step title="Locate the project folder">
    Find the project folder in the file storage, for example `D:\FileStorage\7F7C83FB-7153-4985-A6BE-43BD242D466B\ProjectName`. The GUID is stored in the settings table of the database.
  </Step>

  <Step title="Name the JSON file">
    Name the file in the form `3-1-ProjectData0`, replacing the second digit with the project ID. You do not need to specify a file extension.
  </Step>
</Steps>

The example file name `3-1-ProjectData0` breaks down as follows:

| Element       | Meaning                                                       |
| ------------- | ------------------------------------------------------------- |
| `3`           | Predefined prefix (indicates the file relates to the project) |
| `1`           | Project ID (replace this digit)                               |
| `ProjectData` | Predefined name                                               |
| `0`           | File version                                                  |
