+Moodlamp scripting
+---------
+Prismatik uses [QJSEngine](https://doc.qt.io/qt-5/qjsengine.html) for parsing and running moodlamp scripts, so if you are familiar with JavaScript you'll be fine.
+
+The scripts live in your user's Prismatik folder:
+- Windows: `C:\Users\<you>\Prismatik\moodlamps`
+- macOS & Linux: `~/.Prismatik/moodlamps`
+
+File name should obey these rules:
+- allowed characters `a-z`, `0-9` and `_` (underscore)
+- `.mjs` extension
+- unique name
+
+For ex: `my_cool_lamp.mjs`
+
+
+**The bare minimum template:**
+```js
+export const name = "your lamp name here"
+export const interval = 50 // frame time in ms
+
+/**
+ * @param {integer}	baseColor	integer RGB value of the base color that is selected in Prismatik
+ * @param {array}	colors		array of RGB integers representing your LEDs
+ * @return {array}	array of new RGB integers representing your LEDs
+ */
+export function tick(baseColor, colors)
+{
+	for (let i = 0; i < colors.length; i++)
+	{
+		// your code here, for ex:
+		colors[i] = baseColor // will set all LEDs to the color you set in Prismatik
+	}
+
+	return colors
+}
+```
+
+
+**More examples:**
+
+```js
+export const name = "your lamp name here"
+export const interval = 50 // frame time in ms
+
+// if you need a global constant
+const myBlueConst = 0x0000FF // blue color
+
+// if you need a variable that persists between frames (a counter for ex), declare it here
+let someVariable = 0
+
+export function tick(baseColor, colors)
+{
+	for (let i = 0; i < colors.length; i++)
+	{
+		// to set all your LEDs to white
+		colors[i] = 0xFFFFFF
+		// or to blue
+		colors[i] = myBlueConst
+
+		// random colors for each LED
+		colors[i] = Math.round(Math.random() * 0xFFFFFF)
+	}
+
+	someVariable++ // counter from above
+
+	return colors
+}
+
+```
+
+**Recommended way:**
+
+For convenience, Prismatik partially exposes `QColor` class, see [here for documentation](https://doc.qt.io/qt-5/qcolor.html) and [here for exposed methods](/Software/src/QColorMetaWrapper.hpp).
+Prismatik uses `QColor` internally so for best compatibility it's better to use this class.
+Raw RGB values should work, but use them at your own risk.
+
+Example from `rgb_is_life.js`:
+```js
+export const name = "RGB is Life"
+export const interval = 33 // ms
+
+const speed = 1.5
+
+let m_frames = 0
+
+export function tick(baseColor, colors)
+{
+	// transform base RGB value into QColor
+	baseColor = new QColor(baseColor)
+
+	// RGB transition math
+	const degrees = 360.0 / colors.length
+	const step = speed * m_frames++
+	for (let i = 0; i < colors.length; i++)
+	{
+		// transform current color for a given LED into QColor
+		let color = new QColor(colors[i])
+
+		// increment baseColor's hue value for that smooth RGB rotation
+		const hue = baseColor.hslHue() + degrees * i + step
+
+		// set new hue while preserving baseColor's saturation and lightness
+		color.setHsl(hue, baseColor.hslSaturation(), baseColor.lightness())
+
+		// assign the new color
+		// colors[] has to contain .rgb() values
+		colors[i] = color.rgb()
+	}
+	if (step > 360)
+		m_frames = 0
+
+	return colors
+}
+```
+
+
+To see your changes use the reload button or relaunch the app.
+
+
+**Warnig:** scripts bundled with Prismatik are overwritten on launch, if you want to customize Prismatik's scripts, make sure to make a copy of them and modify those.
+
+
+**Logging and console**
+
+If you enable logs in Prismatik your JS errors will be logged to
+- Windows: `C:\Users\<you>\Prismatik\Logs`
+- macOS & Linux: `~/.Prismatik/Logs`
+
+
+You can also enable the [Console API](https://doc.qt.io/qt-5/qtquick-debugging.html#console-api)
+
+```js
+export const enableConsole = true
+...
+export function tick()
+{
+	...
+	console.log("some debug")
+	...
+}
+```
+
+Don't forget to remove when you are done
