+## Plugins custom commands
+Since version 1.2.0 introduced custom camera plugin commands system. Commonly to read help just
+type `-_help`. You can point as much custom commands in one commandline as you need. They can be a
+procedures/flags (like `-_cmd`) or a setters/getters (like `-_key` and `-_key=value`).
+
+### Dummy camera plugin custom commands
+This plugin simply emulates image aqcuisition process where images are 2-D sinusoide with given periods.
+Each next frame will be shifted by one pixel.
+
+Commands:
+
+- px = (double) [1, inf] - set/get sin period over X axis (pix)
+- py = (double) [1, inf] - set/get sin period over Y axis (pix)
+
+
+### Artifical star plugin custom commands
+This plugin lets you to emulate star field with up to 32 stars. You can shift center of field emulating
+telescope correction, also you can rotate field emulating derotation.
+All stars (Moffat) have the same FWHM and scale parameters. Their coordinates are given by arrays `x`
+and `y` with a hardware magnitude `mag`. You can emulate image drift and rotation. Also you can add
+a little image position (full frame position) fluctuations. To emulate poisson noice just point its `lambda`
+value (`lambda==1` means no noise).
+
+Commands:
+
+-    xc = (int) - x center of field in array coordinates
+-    yc = (int) - y center of field in array coordinates
+-    x - X coordinate of next star
+-    y - Y coordinate of next star
+-    fwhm = (double) [0.1, 10] - stars min FWHM, arcsec
+-    scale = (double) [0.001, 3600] - CCD scale: arcsec/pix
+-    mag - Next star magnitude: 0m is 0xffff/0xff (16/8 bit) ADUs per second
+-    mask - load mask image (binary, ANDed)
+-    vx = (double) [-20, 20] - X axe drift speed (arcsec/s)
+-    vy = (double) [-20, 20] - Y axe drift speed (arcsec/s)
+-    vr = (double) [-36000, 36000] - rotation speed (arcsec/s)
+-    fluct = (double) [0, 3] - stars position fluctuations (arcsec per sec)
+-    beta = (double) [0.5, inf] - Moffat `beta` parameter
+-    lambda = (double) [1, inf] - Poisson noice lambda value (>1)
+-    rotangle = (double) [0, 1.296e+06] - Starting rotation angle (arcsec)
