-# Vosk Speech Recognition Toolkit
+# About
 
 Vosk is an offline open source speech recognition toolkit. It enables
-speech recognition for 20+ languages and dialects - English, Indian
+speech recognition models for 18 languages and dialects - English, Indian
 English, German, French, Spanish, Portuguese, Chinese, Russian, Turkish,
 Vietnamese, Italian, Dutch, Catalan, Arabic, Greek, Farsi, Filipino,
-Ukrainian, Kazakh, Swedish, Japanese, Esperanto, Hindi, Czech, Polish.
-More to come.
+Ukrainian.
 
 Vosk models are small (50 Mb) but provide continuous large vocabulary
 transcription, zero-latency response with streaming API, reconfigurable
 vocabulary and speaker identification.
 
 Speech recognition bindings implemented for various programming languages
-like Python, Java, Node.JS, C#, C++, Rust, Go and others.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,

-# Maintenance
-
-To maintain this module, please ensure the following.
-1. Kotlin version is kept up to date.
-This will be found in the plugins block of the [build.gradle.kts](./build.gradle.kts).
-Ensure both multiplatform and serialization have the same value.
-2. Ensure dependencies are up to date
-3. Ensure that the android min & target sdks are up to date.

-# vosk-api-kotlin
-
-The vosk-api wrapped using Kotlin Multiplatform.
-
-## Usage
-
-The following are ways to use this wrapper.
-
-### JVM
-
-For Java & Android targets.
-
-```kotlin
-dependencoes {
-    val voskVersion = "0.4.0-alpha0"
-
-    // Generic
-    implementation("com.alphacephei:vosk-api-kotlin:$voskVersion")
-
-    // Android
-    implementation("com.alphacephei:vosk-api-kotlin-android:$voskVersion")
-}
-```
-
-## Building
-
-To build this project, follow the following steps.
-
-1. Install `libvosk`.
-This can be done from [source][source install] (parent monorepo) 
-or [downloaded][download].
-2. Download a [Vosk model](https://alphacephei.com/vosk/models) to use.
-  - It is suggested to use a small model to speed up tests.
-3. Once both are downloaded and placed into a proper location (hopefully following UNIX specification).
-Set the following environment variables:
-  - `VOSK_MODEL` to the path of the model.
-  - `VOSK_PATH` to the path of `libvosk`.
-These are used by the various tests to operate.
-4. Now that the required steps are complete, one can run `./gradlew build`.
-
-## Kotlin/Native
-
-Currently, the native target is disabled due to a lack of vosk-api packaging on platforms.
-Further worsened by the fact that installing the vosk-api on Linux systems is a chore.
-
-First, either install from [source][source install]
-or [download][download] and install into the proper unix directories as expected in
-[libvosk.def](./src/nativeInterop/cinterop/libvosk.def).
-
-To enable development for Kotlin/Native, do either for the following.
-- Add `NATIVE_EXPERIMENT=true` to your environment.
-- Go into [build.gradle.kts](./build.gradle.kts) & find `enableNative` & set the right side to true.
-
-Afterwards, when syncing the project, the native source sets will become available to work on.
-It is suggested to run `cinteropLibvoskNative` to generate the Kotlin C bindings to work with.
-
-## Future
-
-- Possibly target Kotlin/JS
-- Possibly target Kotlin/Objective-C (?)
-
-[source install]: https://alphacephei.com/vosk/install
