 === Create New Seed ===
 This doesn't do anything at the moment. Eventually it will replace the *Random Seed* with a new random number.
+=== Noise Frequency ===
+The randomness of the placement of the images as well as their rotation, scale, etc. is based on a noise function. This setting changes the scale of that noise.
+Larger values make it more chaotic, smaller values less so, which will lead to images next to each other using more similar settings.
 === Probability ===
 The probability a bitmap will show up.

 == Max ==
 This is the maximum transparency value if **Randomize** is enabled. The random transparency will be in the range from **Base** to this value.
+===== Node Connections =====
+==== Inputs ====
+==== Projection ====
+Connect a Projection node to define the texture projection used for the node. If it's not connected, the default UV Map will be used if has been defined.
+The other inputs correspond to the controls with the same name. Please remember that the inputs change the values per (surface) spot that is evaluated.
+==== Outputs ====
+=== Colour ===
+This is the final composite of the random images over the background colour.
+=== RGB ===
+This is just the colour of the random images. If no image is visible at a spot, it will be black.
+=== Luma ===
+This is the luminosity of the **RGB** output.
+=== Alpha ===
+The transparency of the random images, taking their respective alpha channels into account.
+=== Bump ===
+A bump map computed from the luminosity of the images.
+=== Tile Value ===
+This is a random value between black and white (0 .. 1.0) for each tile, taking the alpha channel of the mapped images into account.
