+Size scheme is the set of configuration options that change paddings of various theme elements: buttons, text, etc.
+
+Configuration options are divided by **layers** - groups of color options. Higher levels are for more granular options. Only **layer 1** is required, but since `theme.conf` already contains these options, they can be omitted in `theme.conf.user`, but it's recommended to redefine them, as they can define full color scheme.
+
+Size option is defined by single integer (both negative and positive).
+
+Levels that are higher than 1 have **fallback sizes** to current or lower levels, so they can be optional and you could set options that you need. Fallback sizes will check every option from left to right for existing, and will use first existing option.
+
+If fallback is shown as "`fallback...`" it means that `fallback`'s fallback sizes are also applied. Example:
+
+* `option` fallbacks are `other_option`, `fall...`;
+* `fall` fallbacks are `size`;
+* so `option` fallbacks will be `other_option`, `fall`, `size`.
+
+### Current layers
+
+* Layer 1 - size options that are mandatory.
+* Layer 2 - common size options.
+* Layer 3 - sizes for specific control groups.
