 This library provides functionality to extract information stored within PNG images generated by Stable Diffusion Web UI.
 
-## Usage
+It also provides functions to mutually convert between infotext and JSON formats.
+
+## Usage（extract infotext in PNG images)
+
+You can use `getInfotext` or `getInfotextJson` to extract infotext embedded in PNG images.
 
 Support `CJS/ESM/UMD`
 
 ### CommonJS
 
 ```javascript
-const { getPngInfo } = require('chilled-lemon');
+const { getInfotext, getInfotextJson } = require('chilled-lemon');
 const { readFile } = require('node:fs/promises');
 
 (async () => {
     const buf = await readFile('./test.png');
-    const jsonOutput = await getPngInfo(buf);
-    console.log(jsonOutput);
-    const textOutput = await getPngInfo(buf, { format: 'text' });
-    console.log(textOutput);
+
+    const infotext = await getInfotext(buf);
+    console.log(infotext);
+
+    const json = await getInfotextJson(buf);
+    console.log(json);
 })();
 ```
 
 ### ES Modules
 
 ```javascript
-import { getPngInfo } from 'chilled-lemon';
+import { getInfotext, getInfotextJson } from 'chilled-lemon';
 import { readFile } from 'node:fs/promises';
 
 const buf = await readFile('./test.png');
-const jsonOutput = await getPngInfo(buf);
-console.log(jsonOutput);
-const textOutput = await getPngInfo(buf, { format: 'text' });
-console.log(textOutput);
+
+const infotext = await getInfotext(buf);
+console.log(infotext);
+
+const json = await getInfotextJson(buf);
+console.log(json);

-## Methods and Types
-
-```typescript
-import { getPngInfo, getOriginalKeyNames, PngInfoObject, OriginalKeyPngInfoObject, LoraHash } from 'chilled-lemon';
-```
-
-### Methods
 
-### getPngInfo(arrayBuffer: ArrayBuffer, options?: Options): Promise<PngInfoObject | string>
+## Usage (Conversion between infotext and JSON)
 
-Extracts the information from a PNG image represented by an ArrayBuffer. The options argument allows you to specify the format in which the extracted data should be returned: 'json' (default) or 'text'.
+You can use `convertInfotextToJson` and `convertJsonToInfotext` to convert between infotext and JSON.
 
-#### Parameters
-* `arrayBuffer` An ArrayBuffer representation of the PNG image to extract information from.
-* `options` (Optional) An object specifying options for the function. Available options are:
-  * `format` The format in which the function should return the extracted information. This can either be 'json' or 'text'. If not specified, 'json' is used by default.
-
-#### Returns
-A promise which resolves to either an object representing the information extracted from the PNG image (PngInfoObject) if the format option is set to 'json', or a string if the format option is set to 'text'.
-
-### getOriginalKeyNames(obj: PngInfoObject): OriginalKeyPngInfoObject
-
-Converts the keys of a PngInfoObject from the library's internal naming scheme back to their original names.
-
-#### Parameters
-* `obj` A PngInfoObject whose keys should be converted.
+```javascript
+import { getInfotext, getInfotextJson, convertInfotextToJson, convertJsonToInfotext } from 'chilled-lemon';
+import { readFile } from 'node:fs/promises';
 
-#### Returns
-An OriginalKeyPngInfoObject whose keys have been converted back to their original names.
+const buf = await readFile('./test.png');
 
-### Types
+const infotext = await getInfotext(buf);
+const convertedJson = await convertInfotextToJson(infotext);
+console.log(convertedJson)
 
-### PngInfoObject
+const json = await getInfotextJson(buf);
+const convertedInfotext = await convertJsonToInfotext(json);
+console.log(convertedInfotext);
+```
 
-An object representing the information extracted from a PNG image. The keys of this object correspond to the different pieces of information that can be stored in a PNG image by Stable Diffusion Web UI.
+## Development
 
-### OriginalKeyPngInfoObject
+### Code formatter
 
-A version of PngInfoObject where the keys have been converted back to their original names.
+We are currently utilizing "deno fmt" as our code formatter. In order to use this, developers will need to have Deno installed on their PC.
 
+At the moment, I am the sole developer working on this project, which is why I chose "deno fmt".  
+it allows for easy code formatting without the necessity to include dependent packages in the project.
 
-### LoraHash
-An object representing a set of Lora hashes. This object's keys are the names of the Lora hashes, and its values are the corresponding hash values.
+In the future, should we expand our team and if other developers express a preference for a different formatter, I am open to discussions and would appreciate if the suggestions are raised as issues for consideration.
