 ## Usage
 
-CLI takes to arguments `-i` and `-o`:
-* `-i` or `--input` - Specify the input JSON file.
-* `-o` or `--output` - Specify the output folder.
+As of v2 CLI includes and alias for the name, `dte` (Devtools Timeline Export). This has been changed as in the future
+there is a plan to export videos, not only images.
+
+### Image
+
+```bash
+dte images <input> [options]
+
+Generate sequence of images.
+
+Options:
+  --version     Show version number                                    [boolean]
+  --output, -o  Path to JSON file generated by Chrome.       [string] [required]
+  -h, --help    Show help                                              [boolean]
+```
+
+Also you can generate images with an alias `i`, like this: `dte i <input> [options]`.
+
+## Options
+- `-o` or `--output` - Specify the output folder.
 
 *Note: If the output directory does not exist the CLI will create it.*
 
 ## Example
 
 ```bash
-devtools-timeline-images -i ./example-site.json -o ./images
+dte i ./example-site.json -o ./images
 ```
