-# Camera extension for Defold
+# extension-camera
 
-Defold [native extension](https://www.defold.com/manuals/extensions/) which provides access to the camera on macOS, iOS and Android.
+Native extension to use device camera to capture frames.
 
-[Manual, API and setup instructions](https://www.defold.com/extension-camera/) is available on the official Defold site.
+
+# Installation
+
+To use the camera extension in a Defold project this project has to be added as a [Defold library dependency](http://www.defold.com/manuals/libraries/). Open the **game.project** file and in the [Dependencies field in the Project section](https://defold.com/manuals/project-settings/#dependencies) add:
+
+https://github.com/defold/extension-camera/archive/master.zip
+
+Or point to the ZIP file of [a specific release](https://github.com/defold/extension-camera/releases).
+
+
+# Supported platforms
+
+The currently supported platforms are macOS, iOS and Android
+
+
+# FAQ
+
+## How do I reset macOS camera permission?
+
+To test macOS camera permission popup multiple times you can reset the permission from the terminal:
+
+```bash
+tccutil reset Camera
+```
+
+
+# Lua API
+
+## Type constants
+
+Describes what camera should be used.
+
+```lua
+camera.CAMERA_TYPE_FRONT -- Selfie
+camera.CAMERA_TYPE_BACK
+```
+
+
+## Quality constants
+
+```lua
+camera.CAPTURE_QUALITY_HIGH
+camera.CAPTURE_QUALITY_MEDIUM
+camera.CAPTURE_QUALITY_LOW
+```
+
+
+## Status constants
+
+```lua
+camera.CAMERA_STARTED
+camera.CAMERA_STOPPED
+camera.CAMERA_NOT_PERMITTED
+camera.CAMERA_ERROR
+```
+
+
+## camera.start_capture(type, quality, callback)
+
+Start camera capture using the specified camera (front/back) and capture quality. This may trigger a camera usage permission popup. When the popup has been dismissed the callback will be invoked with camera start status.
+
+```lua
+camera.start_capture(camera.CAMERA_TYPE_BACK, camera.CAPTURE_QUALITY_HIGH, function(self, message)
+    if message == camera.CAMERA_STARTED then
+        -- do stuff
+    end
+end)
+```
+
+
+## camera.stop_capture()
+
+Stops a previously started capture session.
+
+```lua
+camera.stop_capture()
+```
+
+
+## camera.get_info()
+
+Gets the info from the current capture session.
+
+```lua
+local info = camera.get_info()
+print("width", info.width)
+print("height", info.height)
+```
+
+
+## camera.get_frame()
+
+Retrieves the camera pixel buffer. This buffer has one stream named "rgb", and is of type `buffer.VALUE_TYPE_UINT8` and has the value count of 1.
+
+```lua
+self.cameraframe = camera.get_frame()
+```
