 ### Features
 
 - File de-duplication based on content
 - File encryption with AES-256-GCM
+- File compression with gzip
 - Metadata sqlite database that can be queried with SQL
 - File name mangling with the content SHA512 hash

 Will export all files in the filesystem to the specified path in the specified format. Supports `zip`, `tar`
 and `directory`.
 
+- Stats
+
+```bash
+innerfs stats
+```
+
+Will print a JSON file with statistics about the filesystem, number of files, directories, sizes, etc.
+
+- Verify integrity
+
+```bash
+innerfs verify
+```
+
+Will verify the integrity of the filesystem, checking the metadata database and the file contents.
+
 ### Configuration
 
 The default configuration file contains comments that explain the options, can be seen [here](./src/default_config.yml).
 
+### Installation
+
+You can download the latest release from the [releases page](https://github.com/cout970/InnerFS/releases) or build from
+source using `cargo build --release` on a copy of the repo.
+
+It is necessary to have FUSE installed, it is usually available in the package manager of most distributions named '
+fuse' or 'fuse3'.
+
+### Limitations
+
+- The filesystem is not fully POSIX compliant, some operations may not work as expected: append, fallocate, symlinks,
+  hardlinks, etc.
+- If the database file is lost, the access to the files could be lost, for example, if encryption is enabled, the key
+  salt and nonce are stored in the database.
+- Performance will be worse than a traditional filesystem, as every operation is done in a single thread.
+- Files will be fully loaded in memory for read/write operations, so be careful with huge files.
+
