+# Sanskrit Text-to-Speech 🕉️
+### Generate text-to-speech for Sanskrit.
+#### संस्कृत वाङ्निर्मिति
+
+## Installation ⬇️
+```
+$ npm install sanskrit-tts
+```
+
+## Usage
+#### Import the `sanskrit-tts` module:
+```ts
+import tts from "sanskrit-tts"
+```
+```js
+const tts = require("sanskrit-tts") // CommonJS
+```
+
+### Methods
+#### 💾 Save to disk:
+```js
+tts.saveFile("aham vanam gacchāmi", { 
+    script: "iast", 
+    fileName: "audio.mp3" 
+});
+```
+You can make it ***slower*** if you need:
+```js
+tts.saveFile("अहं वक्तुं शक्नोमि", { 
+    script: "devanagari", 
+    slow: true, 
+    fileName: "audio.mp3" 
+});
+```
+
+#### 🔗 Get URL:
+```js
+let url = tts.getURL("कथम् अस्ति भवान्", { script: "devanagari" })
+console.log(url);
+
+// Returns: https://translate.google.com/translate_tts...
+```
+
+#### 🔢 Get Audio in Base64 encoding:
+```js
+let base64 = tts.getBase64("ओम् नमः शिवाय", { script: "devanagari" })
+console.log(base64);
+```
+
+#### 🔗 Get All URLs (For queries more than 200 characters): 🔗
+```js
+let urls = tts.getAllURLs("गणितम् पठामः", { script: "devanagari" })
+console.log(urls);
+
+// Returns [Array]
+```
+> You can also do the same to get Base64 encodings for queries more than 200 characters using `tts.getAllBase64()`. 
+
+### 🆎 Supported Scripts
