-## Major changes in v3
- Significantly faster performance
-   - Runtime reduction of 84% for Browser and 96% for Node.js when recognizing the [example images](./examples/data)
- Upgrade to Tesseract v5.1.0 (using emscripten 3.1.18)
- Added SIMD-enabled build for supported devices
- Added support:
-   - Node.js version 18
- Removed support:
-   - ASM.js version, any other old versions of Tesseract.js-core (<3.0.0) 
-   - Node.js versions 10 and 12

 # Image Format

-The main Tesseract.js functions (ex. recognize, detect) take an `image` parameter.  The image formats and data types supported are listed below. 
+Support Format: **bmp, jpg, png, pbm**

-Support Image Formats: **bmp, jpg, png, pbm, webp**
+The main Tesseract.js functions (ex. recognize, detect) take an `image` parameter, which should be something that is like an image. What's considered "image-like" differs depending on whether it is being run from the browser or through NodeJS.

-For browser and Node, supported data types are:
- - string with base64 encoded image (fits `data:image\/([a-zA-Z]*);base64,([^"]*)` regexp)
- - buffer
+On a browser, an image can be:
+- an `img`, `video`, or `canvas` element
+- a `File` object (from a file `<input>`)
+- a `Blob` object
+- a path or URL to an accessible image
+- a base64 encoded image fits `data:image\/([a-zA-Z]*);base64,([^"]*)` regexp

-For browser only, supported data types are:
- - `File` or `Blob` object
- - `img` or `canvas` element
-
-For Node only, supported data types are:
- - string containing a path to local image
-
-Note: images must be a supported image format **and** a supported data type.  For example, a buffer containing a png image is supported.  A buffer containing raw pixel data is not supported. 
+In Node.js, an image can be
+- a path to a local image
+- a Buffer storing binary image 
+- a base64 encoded image fits `data:image\/([a-zA-Z]*);base64,([^"]*)` regexp
