 The output is a single-file JSON export. The JSON export is opinionated and ignores null values to minimize the exported JSON file size.
 
+**N.B.** Thanks to dotnet 8.0, it should run cross-platform. But it has not been tested on Linux and MacOS platforms.

 # Usage
 
 ## Export JSON
 
 Extract the ntds.dit file from the host and run using the following:
+
 ```
 ditjson -n path\to\ntds.dit\file
 ```
 
+This will process only `datatable` and `link_table`.
+
 Once the process has been completed it will have generated two output files in the application directory:
 
 - ntds.json
 
+
+## Export JSON  for specific tables
+
+Extract the ntds.dit file from the host and run using the following:
+
+```
+ditjson -n path\to\ntds.dit\file -t datatable
+```
+
+This will process only `datatable`.
+
+
+## Export JSON  for *all* tables
+
+Extract the ntds.dit file from the host and run using the following:
+
+```
+ditjson -n path\to\ntds.dit\file -t *
+```
+
+This will process all tables inside `ntds.dit` file. Beware of the size.
