 # universalarchive plugin
 
-Lets you compress files by a command `ua <format> <files>`, supporting various
-compression formats (e.g. 7z, tar.gz, lzma, ...).
+The `universalarchive` plugin provides a convenient command-line interface for archiving files and directories using a wide variety of compression formats - without having to remember the exact syntax for each tool.
 
-To enable it, add `universalarchive` to the plugins array in your zshrc file:
+To enable it, add `universalarchive` to the plugins array in your `.zshrc` file:
 
 ```zsh
 plugins=(... universalarchive)
 ```
 
+## Features
+ - Compress files and directories using a simple, unified command: ua <format> <files>
+ - Automatically detects file/directory names to generate appropriate output names
+ - Supports fallback naming if an output file already exists
+ - Works with many common and advanced compression formats
+ - Designed for simplicity and quick use in the terminal
+
 ## Usage
 
-Run `ua <format> <files>` to compress `<files>` into an archive file using `<format>`.
-For example:
+Basic command format:
+```sh
+ua <format> <files...>
+```
+- `<format>`: the archive format to use (e.g., `zip`, `tar.gz`, `xz`, `7z`, etc.)
+- `<files...>`: one or more files or directories to compress
+
+## Examples:
+
+Compresses `notes.txt` and `images` into `notes.zip`
+```sh
+ua zip notes.txt images/
+```
+
+Creates `myproject.tar.gz`
+```sh
+ua tar.gz myproject/
+```
 
+Compresses all .log files into `current_folder.xz`
 ```sh
-ua xz *.html
+ua xz *.log
 ```
 
-this command will compress all `.html` files in directory `folder` into `folder.xz`.
+The plugin will generate a default archive filename based on the input:
+ - For a file, the output is derived from the file name without its extension.
+ - For a directory, it uses the directory name.
+ - For multiple files, it uses the name of the common parent directory.
+
+ If the output file already exists, a unique filename is generated using `mktemp`.
+
+## Supported Archive Formats
