 ### Temporary Directory for Apache POI
 (This addresses [issue 293](https://github.com/OHDSI/WhiteRabbit/issues/293))
 
-The Apache POI library is used for generated the report in Excel format. This library creates its own directory for
-temporary files in the system temporary directory. It has been reported that this can cause problems in a multi-user
-environment, when each user attempts to create this directory with too restrictive permissions (read-only for other
-users). WhiteRabbit from version 0.10.9 tries to circumvent this automatically, but this workaround can fail due
-to concurrency problems. If you want to prevent this from happening, you can set either the environment variable
-```ORG_OHDSI_WHITERABBIT_POI_TMPDIR``` or the Java system property ```org.ohdsi.whiterabbit.poi.tmpdir``` when starting
-WhiteRabbit (best would be to add this to the ```whiteRabbit``` or ```whiteRabbit.bat``` script). Please note that
-this directory should exist before your start WhiteRabbit, and is writable by any user that may want to run
-WhiteRabbit. Each user will then have a separate subdirectory, so that further conflicts should be avoided.
-Also, WhiteRabbit now attempts to detect this situation before the scan starts, so that the scan is not started, and
-the problem identified sooner.
