| **WARNING**
 | |
|   Legacy configuration paths have been detected.
 | |
| 
 | |
|   Beginning with version 2.0.0, yadm uses the XDG Base Directory Specification
 | |
|   to find its configurations. Read more about this change here:
 | |
| 
 | |
|     https://yadm.io/docs/upgrade_from_1
 | |
| 
 | |
|   In your environment, the configuration directory has been resolved to:
 | |
| 
 | |
|     $YADM_DIR
 | |
| 
 | |
|   To remove this warning do one of the following:
 | |
|     * Run "yadm upgrade" to move the yadm data to the new directory. (RECOMMENDED)
 | |
|     * Manually move yadm configurations to the directory listed above.
 | |
|     * Specify your preferred yadm directory with -Y each execution.
 | |
|     * Define an environment variable "YADM_COMPATIBILITY=1" to run in version 1
 | |
|       compatibility mode. (DEPRECATED)
