+
+Once unpacked, in the root folder (`dhfs`), there will be 3 folders:

+- `app` contains the application
+- `data` contains the filesystem data storage
+- `fuse` is the default filesystem mount point (not on Windows, the default mount drive letter is `Z`)
+
+Note that on Windows, the path to the root can not contain spaces.
 
 ## How to use it?
 
 ### General prerequisites
 
-Java should be available as `java` in path, and Java 21+ is required.
+Java should be available as `java` in `PATH`, or with a correctly set `JAVA_HOME` (ignored on Windows), and Java 21 is required.
 
 FUSE 2 userspace library also should be available:
 
-- On Ubuntu `libfuse2` package can be installed.

-- On Windows, [WinFsp](https://winfsp.dev/) should be installed.

-In the run-wrapper, 3 scripts are available.
+### How to run it?
+
+In the run-wrapper `app` folder, 3 scripts are available.
 
 - `run` script starts the filesystem
 - `stop` script stops it
 - `update` script will update the filesystem to the newest available CI build
 
-On Windows, Powershell alternatives should be used. For them to work, it might be required to allow execution of unsigned scripts using `set-executionpolicy remotesigned`.
+On Windows, Powershell versions of the scripts should be used. For them to work, it might be required to allow execution of unsigned scripts using `set-executionpolicy unrestricted`.
+
+### Additional options
 
 Additional options for the filesystem can be specified in the `extra-opts` file in the same directory with the run scripts.
 
-One line in the `extra-opts` file corresponds to one option passed to the JVM when starting the filesystem. 
+One line in the `extra-opts` file corresponds to one option passed to the JVM when starting the filesystem.
 
 Some extra possible configuration options are:
 
-- `-Ddhfs.fuse.root=` specifies the root where filesystem should be mounted. By default it is the `fuse` path under the `run-wrapper` root. For windows, it should be a disk letter, by default `Z:\`.
+- `-Ddhfs.fuse.root=` specifies the root where filesystem should be mounted. By default, it is the `fuse` path under the `run-wrapper` root. For windows, it should be a disk root, by default `Z:\`.
-- `-Ddhfs.objects.last-seen.timeout=` specifies the period of time (in seconds) after which unavailable peers will be ignored for gabgage collection and resynchronized after being reconnected. The default is 43200 (30 days), if set to `-1`, this feature is disabled.
+- `-Ddhfs.objects.last-seen.timeout=` specifies the period of time (in seconds) after which unavailable peers will be ignored for garbage collection and resynchronized after being reconnected. The default is 43200 (30 days), if set to `-1`, this feature is disabled.
 - `-Ddhfs.objects.autosync.download-all=` specifies whether all objects (files and their data) should be downloaded to this peer. `true` or `false`, the default is `false`.
+- `-Ddhfs.objects.peerdiscovery.port=` port to broadcast on and listen to for LAN peer discovery (default is `42262`)
+- `-Ddhfs.objects.peerdiscovery.broadcast=` whether to enable local peer discovery or not (default is `true`)
+- `-Dquarkus.http.port=` HTTP port to listen on (default is `8080`)
+- `-Dquarkus.http.ssl-port=` HTTPS port to listen on (default is `8443`)
+- `-Dquarkus.http.host=` IP address to listen on (default is `0.0.0.0`)
+- `-Ddhfs.peerdiscovery.static-peers=` allows to manually specify a peer's address in format of `peer id:http port:https port`, for example `-Ddhfs.peerdiscovery.static-peers=11000000-0000-0000-0000-000000000000:127.0.0.1:9010:9011`
 
-On Windows, the entire space for the filesystem should also be preallocated, the `-Ddhfs.objects.persistence.lmdb.size=` option controls the size (the value is in bytes), on Windows the default is 100GB.

-Then, a web interface will be available at `losthost:8080`, that can be used to connect with other peers.
+In case of errors, the standard output is redirected to `quarkus.log` in the `app` folder, on Windows the error output is separate.
+
+### How to connect to other peers?
+
+Then, a web interface will be available at `losthost:8080` (or whatever the HTTP port is), that can be used to connect with other peers. Peers on local network should be available to be connected to automatically.
+
+## Other notes
+
+### Running tests
+
+To run LazyFS tests, LazyFS needs to be built: the git submodules need to be cloned and `./thirdparty/lazyfs/build.sh` script needs to be run. 
+
+LazyFS tests were only tested on Linux.
