 ## Testing locally
 
-To test your contribution locally from the command line, run the Python script in the following format:
+To test your contribution locally from the command line, clone the repository and create a `repo` helper folder with files to upload:
 
 ```
-python dataverse.py DATAVERSE_TOKEN DATAVERSE_SERVER DATASET_DOI REPO_NAME
+git clone https://github.com/IQSS/dataverse-uploader.git
+cd dataverse-uploader
+mkdir repo # here store test folders and files for upload
 ```
+### Set up the environment
 
-Example:
+Next, install the necessary dependencies:
+
+```
+python3 -m venv env
+source env/bin/activate
+python3 -m pip install -r requirements.txt
+```
+
+Now, the folder should look like this:
 ```
-python dataverse.py 9s3-7d46-hd https://demo.dataverse.org/ doi:10.70122/FK2/LVUADQ user/my-repo 
+$ ls
+CONTRIBUTING.md		README.md		dataverse.py		repo
+LICENSE			action.yml		env			requirements.txt
 ```
 
-You can append this command with optional arguments such as `--dir data --remove False --publish True`
+### Testing commands
+
+Run the Python script in the following format:
+
+```
+python dataverse.py DATAVERSE_TOKEN DATAVERSE_SERVER DATASET_DOI REPO_NAME -p TRUE
+```
+
+- `DATAVERSE_TOKEN` - dataverse token should be a valid token
+- `DATAVERSE_SERVER` - for testing use https://demo.dataverse.org/
+- `DATASET_DOI` - it should be a valid PID from Dataverse demo or a Dataverse instalation 
+- `REPO_NAME` - for the local test, this is a **mock GitHub repository name**, and it should be a string, such as "user/my-repo" or similar
+
+The script will upload everything from **the helper `repo` folder** to the `DATAVERSE_SERVER` at dataset `DATASET_DOI`.
+
+### Examples
+
+- The basic format of the command will upload and publish everything from the helper `repo` folder.
+
+```
+python dataverse.py 9s3-7d46-hd https://demo.dataverse.org/ doi:10.70122/FK2/LVUADQ user/my-repo -p TRUE
+```
+
+- To upload files from a single folder, use:
+
+```
+python dataverse.py 9s3-7d46-hd https://demo.dataverse.org/ doi:10.70122/FK2/LVUADQ user/my-repo -d first_dir -p TRUE
+```
+
+There needs to be a folder named `first_dir` that contains files inside the helper `repo` folder.
+
+- To upload multiple folders, use the command:
+
+```
+python dataverse.py 9s3-7d46-hd https://demo.dataverse.org/ doi:10.70122/FK2/LVUADQ user/my-repo -d first_dir,second_dir,third_dir -p TRUE
+```
+
+The multiple directories with files need to be stored inside the helper `repo` folder.
+
+- You can append this command with optional arguments such as `--remove/-r False` and `--publish/-p True`:
+
+```
+python dataverse.py 9s3-7d46-hd https://demo.dataverse.org/ doi:10.70122/FK2/LVUADQ user/my-repo -r False -p True
+```
