 CHANGELOG
 =========
 
+0.21.0
+------
+- `--height` option is now available on Windows as well (@kelleyma49)
+- Added `--pointer` and `--marker` options
+- Added `--keep-right` option that keeps the right end of the line visible
+  when it's too long
+- Style changes
+    - `--border` will now print border with rounded corners around the
+      finder instead of printing horizontal lines above and below it.
+      The previous style is available via `--border=horizontal`
+    - Unicode spinner
+- More keys and actions for `--bind`
+- Added PowerShell script for downloading Windows binary
+- Vim plugin: Built-in floating windows support
+  ```vim
+  let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
+  ```
+- bash: Various improvements in key bindings (CTRL-T, CTRL-R, ALT-C)
+    - CTRL-R will start with the current command-line as the initial query
+    - CTRL-R properly supports multi-line commands
+- Fuzzy completion API changed
+  ```sh
+  # Previous: fzf arguments given as a single string argument
+  # - This style is still supported, but it's deprecated
+  _fzf_complete "--multi --reverse --prompt=\"doge> \"" "$@" < <(
+    echo foo
+  )
+
+  # New API: multiple fzf arguments before "--"
+  # - Easier to write multiple options
+  _fzf_complete --multi --reverse --prompt="doge> " -- "$@" < <(
+    echo foo
+  )
+  ```
+- Bug fixes and improvements

 FZF Vim integration
 ===================
 
+Installation
+------------
+
+Once you have fzf installed, you can enable it inside Vim simply by adding the
+directory to `&runtimepath` in your Vim configuration file. The path may
+differ depending on the package manager.
+
+```vim
+" If installed using Homebrew
+set rtp+=/usr/local/opt/fzf
+
+" If installed using git
+set rtp+=~/.fzf
+```
+
+If you use [vim-plug](https://github.com/junegunn/vim-plug), the same can be
+written as:
+
+```vim
+" If installed using Homebrew
+Plug '/usr/local/opt/fzf'
+
+" If installed using git
+Plug '~/.fzf'
+```
+
+But if you want the latest Vim plugin file from GitHub rather than the one
+included in the package, write:
+
+```vim
+Plug 'junegunn/fzf'
+```
+
+The Vim plugin will pick up fzf binary available on the system. If fzf is not
+found on `$PATH`, it will ask you if it should download the latest binary for
+you.
+
+To make sure that you have the latest version of the binary, set up
+post-update hook like so:
+
+```vim
+Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
+```

+
+`g:fzf_colors` is a dictionary mapping fzf elements to a color specification
+list:
+
+    element: [ component, group1 [, group2, ...] ]
+
+- `element` is an fzf element to apply a color to:
+
+  | Element               | Description                                           |
+  | ---                   | ---                                                   |
+  | `fg`  / `bg`  / `hl`  | Item (foreground / background / highlight)            |
+  | `fg+` / `bg+` / `hl+` | Current item (foreground / background / highlight)    |
+  | `hl`  / `hl+`         | Highlighted substrings (normal / current)             |
+  | `gutter`              | Background of the gutter on the left                  |
+  | `pointer`             | Pointer to the current line (`>`)                     |
+  | `marker`              | Multi-select marker (`>`)                             |
+  | `border`              | Border around the window (`--border` and `--preview`) |
+  | `header`              | Header (`--header` or `--header-lines`)               |
+  | `info`                | Info line (match counters)                            |
+  | `spinner`             | Streaming input indicator                             |
+  | `prompt`              | Prompt before query (`> `)                            |
+
+- `component` specifies the component (`fg` / `bg`) from which to extract the
+  color when considering each of the following highlight groups
+
+- `group1 [, group2, ...]` is a list of highlight groups that are searched (in
+  order) for a matching color definition
+
+For example, consider the following specification:
+
+```vim
+  'prompt':  ['fg', 'Conditional', 'Comment'],
+```
+
+This means we color the **prompt**
+- using the `fg` attribute of the `Conditional` if it exists,
+- otherwise use the `fg` attribute of the `Comment` highlight group if it exists,
+- otherwise fall back to the default color settings for the **prompt**.
+
+You can examine the color option generated according the setting by printing
+the result of `fzf#wrap()` function like so:
+
+```vim
+:echo fzf#wrap()
