 Rename files with your favourite editor
 
-## Installation
-
-Build from source:
-
 ```bash
-git clone https://github.com/js0ny/renamedit.git
+git clone git@github.com:js0ny/renamedit.git
 cd renamedit
 go build
 ```
 
-## Usage
-
 ```bash
-renamedit [options] <directory>
-```
-
-### Options
-
-- `-ignore-ext`: Ignore file extensions when renaming files. This will preserve the original extensions.
-
-### Examples
-
-Basic usage:
-```bash
-renamedit /path/to/directory
-```
-
-Ignore file extensions (useful for batch renaming while preserving extensions):
-```bash
-renamedit -i /path/to/directory
-renamedit --ignore-ext /path/to/directory
-```
-
-## How It Works
-
-1. The program opens a temporary file in your preferred text editor
-2. Edit the file names as needed
-3. Save and exit the editor
-4. The program will rename the files according to your edits
-
-## Environment Variables
-
-- `EDITOR`: Set this to your preferred text editor (defaults to vim)
-
-## Supported Editors
-
-The following editors are explicitly supported with wait flags:
-- Visual Studio Code (code)
-- Sublime Text (subl)
-- Zed Editor (zeditor)
-- Atom (atom)
-- Gedit (gedit)
-- And most terminal editors (vim, nano, etc.)
+renamedit <dir>
