+Software Heritage graph FUSE
+============================
+
+The Software Heritage :ref:`data model <data-model>` is a direct acyclic graph
+with node of different types that correspond to source code artifacts such as
+directories, commits, etc. Using this :ref:`FUSE <swh-graph-cli>` module you can
+locally mount, and then navigate as a virtual file system, a part of the archive
+(a subgraph) rooted at a node of your choice, identified by a :ref:`SWHID
+<persistent-identifiers>`.
+
+To retrieve information about the source code artifacts the FUSE module
+interacts over the network with the Software Heritage archive via the archive
+:ref:`Web API <swh-web-api-urls>`.
+
+File system representation
+--------------------------
+
+Graph node types are represented as:
+
+- `cnt`: regular file, contains the blob bytes stored in the object
+- `dir`: directory
+
+    - entries are listed based on their real entry names and permissions
+
+- `rev`: directory
+
+    - `message`: commit message (regular file)
+    - `author`, `committer`: authorship information (regular files)
+    - `author_date`, `committer_date`: timestamps (regular files containing
+      textual ISO 8601 date and time timestamps)
+    - `root`: source tree at the time of this revision (directory)
+    - `type`: type of originating revisions (regular file containing strings
+      like: git, tar, dsc, svn, hg, etc.)
+    - `metadata.json`: revision metadata (regular file in JSON format)
+    - `synthetic`: whether the object has been synthetized by Software Heritage
+      or not (regular file, containing either 0 (false) or 1 (true))
+
+- `rel`: directory
+
+    - `name`: release name (regular file)
+    - `message`: release message (regular file)
+    - `author`: authorship information (regular file)
+    - `date`: release timestamp (regular file containing a textual ISO 8601 date
+      and time timestamp)
+    - `target`: source tree of the target object (directory)
+    - `metadata.json`: revision metadata (regular file in JSON format)
+    - `synthetic`: whether the object has been synthetized by Software Heritage
+      or not (regular file, containing either 0 (false) or 1 (true))
+
+- `snp`: directory
+
+    - branches entries are listed based on their real names (mangled to account
+      for UNIX naming conventions, e.g: no `/` character)
+
+Examples

+TODO: show the swh/graph/tests/dataset/example graph image and corresponding
+mounting points + examples of different level of information (storage, edge
+labels, etc.)
