 # DMM - DataManagerMount
-Mount your datamanager files into your filesystem
+Mount your datamanager files into your filesystem.
+
+# Prerequisites
+1. A linux kernel with FUSE support
+2. A compiled [binary](https://github.com/DataManager-Go/DMM---DataManagerMount/releases).
+3. A vaild config and session. You can create one using the [cli client](https://github.com/DataManager-Go/DataManagerCLI)
+
+# Get started
+You can mount your dataManager files into your local filesystem using `<dmount> mountPoint`. Thats it.<br>
+
+### Opions
+`--config` use a different configuration file, created by the [CLI client](https://github.com/DataManager-Go/DataManagerCLI) or [GUI client](https://github.com/DataManager-Go/DataManagerGUI)<br>
+`--debug` view more informations about the client server process<br>
+`--debug-fs` view logs for the mount process<br>
+
+# Mapping
+Since the way the datamanager stores your files is different than your Operating Systems fs does, the mapping between Dmanager and your OS filetree isn't that easy.<br>
+The DManager is built to store files assigned to multiple folders (groups) and your FS (usually) allows to store a file in one folder only. In addition, you (usually) can't have multiple files with the same name in one folder.<br>
+The DmanagerFS supports that. This is one of the main differences between Filesystems like ext4 or NTFS and the DataManagerFS.<br>
+
+#### The mapping:
+```bash
+MountPoint
+│
+├── default # The default namespace. Equal to <username>_default
+│   ├── all_files # all files in the default namespace
+│   │   ├── file_in_group1_and_ns_default
+│   │   ├── some other file
+│   │   ├── settings.json
+│   │   ├── Shortcuts
+│   │   ├── settings.json

+│   ├── group1 # Group 1
+│   │   ├── file_in_group1_and_ns_default
+│   │   └── some other file
+│   ├── condig_files
