fastfile: add README

plugins/fastfile/README.md

+# Fastfile plugin
+
+This plugin adds a way to reference certain files or folders used frequently using
+a global alias or shortcut.
+
+To use it, add `fastfile` to the plugins array in your zshrc file:
+```zsh
+plugins=(... fastfile)
+```
+
+## Usage
+
+Example: you access folder `/code/project/backend/database` very frequently.
+
+First, generate a shortcut with the name `pjdb`:
+```zsh
+$ fastfile pjdb /code/project/backend/database
+```
+
+Next time you want to access it, use `§pjdb`. For example:
+```zsh
+$ cd §pjdb
+$ subl §pjdb
+```
+where § is the fastfile prefix (see [below](#options) for how to change).
+
+**Note:** shortcuts with spaces in the name are assigned a global alias
+where the spaces have been substituted with underscores (`_`). For example:
+a shortcut named `"hello world"` corresponds with `§hello_world`.
+
+
+## Functions
+
+- `fastfile <shortcut_name> <path/to/file/or/folder>`: generate a shortcut.
+
+- `fastfile_print <shortcut_name>`: prints a shortcut, with the format
+  `<prefix><shortcut_name> -> <shortcut_path>`.
+
+- `fastfile_ls`: lists all shortcuts.
+
+- `fastfile_rm <shortcut_name> `: remove a shortcut.
+
+- `fastfile_sync`: generates the global aliases for the shortcuts.
+
+
+### Internal functions
+
+- `fastfile_resolv <shortcut_name>`: resolves the location of the shortcut
+  file, i.e., the file in the fastfile directory where the shortcut path
+  is stored.
+
+- `fastfile_get <shortcut_name>`: get the real path of the shortcut.
+
+
+## Aliases
+
+| Alias  | Function         |
+|--------|------------------|
+| ff     | `fastfile`       |
+| ffp    | `fastfile_print` |
+| ffrm   | `fastfile_rm`    |
+| ffls   | `fastfile_ls`    |
+| ffsync | `fastfile_sync`  |
+
+
+## Options
+
+These are options you can set to change certain parts of the plugin. To change
+them, add `<variable>=<value>` to your zshrc file, before Oh My Zsh is sourced.
+For example: `fastfile_var_prefix='@'`.
+
+- `fastfile_var_prefix`: prefix for the global aliases created. Controls the prefix of the
+  created global aliases.  
+  **Default:** `§` (section sign), easy to type in a german keyboard via the combination
+  [`⇧ Shift`+`3`](https://en.wikipedia.org/wiki/German_keyboard_layout#/media/File:KB_Germany.svg),
+  or using `⌥ Option`+`6` in macOS.
+
+- `fastfile_dir`: directory where the fastfile shortcuts are stored. Needs to end
+  with a trailing slash.  
+  **Default:** `$HOME/.fastfile/`.
