@ -45,8 +45,25 @@ In the output above, the `database` parameter refers to a directory containing V
valid database. The `mountpoint` parameter refers to the path on your system where the file system will be accessible
(mounted).
In order to mount a new or existing volume, follow the steps below:
### Listing Volume Versions ###
1. Add yourself to the `fuse` user group if you are not added already (a requirement of FUSE).
2. Execute `./vfs database_dir mountpoint_dir`, using actual paths on your system to mount a volume.
Specifying a database path without the mount point will output a timestamped listing of available versions. This listing
includes identifiers which can be used to specify a specific version to mount with the `-version` parameter. Note that
only read-only mounting is possible of prior versions.

```
### Mounting a Volume ###
1. Add yourself to the `fuse` user group if you are not added already (a requirement of FUSE). You can optionally skip
this step by mounting the volume as the `root` user, but this is not recommended.
2. Execute `./vfs database_dir mountpoint_dir`, using actual paths on your system to mount a volume. If you wish to
provide an identifier for a specific version to mount, you may specify it with the `-version` parameter. Passing a
non-zero value (zero indicates most recent version) will make the mount read-only. Explicit read-only mounting is
also possible by setting the `-readonly` switch.
3. When you are finished using the volume, unmount it via the `fusermount -u mountpoint_dir` command.
