Updated the last change date in the help file

Instead of using the foreground and background of a search result, which
is usually designed to stand right out, the indents for terminal are now
colored according to the normal text background.

 ## Features:
 * Can detect both tab and space indent styles.
-* Automatically inspects your colorscheme and picks appropriate colors.

 * Will highlight indent levels with alternating colors.
+* Full support for gVim and basic support for Terminal Vim.

+* **NEW:** Customizable size for indent guides, eg. skinny guides (soft-tabs only).

 ## Usage
 The default mapping to toggle the plugin is `<Leader>ig`
 
+### gVim
+**This plugin should work with gVim out of the box, no configuration needed.** It will automatically inspect your colorscheme and pick appropriate colors.
+
+### Setting custom indent colors
+Here's an example of how to define custom colors instead of using the ones the plugin automatically generates for you. Add this to your `.vimrc` file:
+
+    let g:indent_guides_auto_colors = 0
+    autocmd VimEnter,Colorscheme * :hi IndentGuidesOdd  guibg=red   ctermbg=3
+    autocmd VimEnter,Colorscheme * :hi IndentGuidesEven guibg=green ctermbg=4
+
+### Terminal Vim
+At the moment Terminal Vim only has basic support. This means is that colors won't be automatically calculated based on your colorscheme. Instead, some preset colors are used depending on whether `background` is set to `dark` or `light`.
+
+When `set background=dark` is used, the following highlight colors will be defined:
+
+    hi IndentGuidesEven ctermbg=darkgrey
+    hi IndentGuidesOdd  ctermbg=black
+
+Alternatively, when `set background=light` is used, the following highlight colors will be defined:
+
+    hi IndentGuidesEven ctermbg=lightgrey
+    hi IndentGuidesOdd  ctermbg=white
+
+If for some reason it's incorrectly defining light highlight colors instead of dark ones or vice versa, the first thing you should check is that the `background` value is being set correctly for your colorscheme. Sometimes it's best to manually set the `background` value in your `.vimrc`, for example:
+
+    colorscheme desert256
+    set background=dark
+
+Alternatively you can manually setup the highlight colors yourself, see `:help indent_guides_auto_colors` for an example.
