 **Data & Storage Management:**
 - `--mount`: Mount a data file into the session. Supports both Lifebit Platform datasets and S3 files (AWS only). Format: `project_name/dataset_path` (e.g., `leila-test/Data/file.csv`) or `s3://bucket/path/to/file` (e.g., `s3://my-bucket/data/file.csv`). Can be used multiple times.
-- `--link`: Link a folder into the session for read/write access (AWS only). Supports S3 folders and Lifebit Platform folders. Format: `s3://bucket/prefix` (e.g., `s3://my-bucket/data/`) or `project_name/folder_path` (e.g., `leila-test/AnalysesResults/analysis_id/results`). Can be used multiple times. **Note:** Linking is not supported on Azure. Use Lifebit Platform file explorer for data access.
+- `--link`: Link a folder into the session for read/write access (AWS only). Supports S3 folders (e.g., `s3://my-bucket/data/`) and File Explorer folders (e.g., `my-project/Data/results`). Multiple folders can be specified using multiple `--link` flags or as comma-separated paths in a single `--link` argument.

 **Data Management**
 
 CloudOS CLI supports multiple ways to access data in interactive sessions, depending on your execution platform:
-- you can load data directly into the session (i.e. files are copied into the session's mounted-data volume)
-- you can link folders to your session  (i.e the folders are sym-linked to the session). This works only for folders (S3-based) and only in AWS enviornments. 
+- **Mount files** (`--mount`): Files are copied into the session's mounted-data volume. Supports CloudOS File Explorer files and S3 files (AWS only).
+- **Link folders** (`--link`): Folders are mounted as read/write accessible directories in the session (AWS only). Supports both S3 folders and Lifebit Platform File Explorer folders. Linked folders appear with unique mount names based on the folder path.
