-#### Example Configuration File
+Refer to the above documentation for information on installing plugins
+
+## Documentation - End User
+
+Getting started with SSHare is about getting familiar with configuring SSHare.
+SSHare configuration is all done in the `${XDG_CONFIG_DIR}/sshare` if set, or in `~/.config/sshare` otherwise.
+In this directory are two important items: the `config.toml` file and the `plugins/` directory.
+
+### `plugins/`
+
+The `plugins/` directory is home to all external plugins. Installing a plugin is as simple as saving the
+the plugin's `.py` file to the `plugins/`.
+
+### `config.toml`
+
+The configuration file can be broken down into three major components: `spec`, `config`, and `flags`.
+
+#### `spec`
 
 ```toml
-# config.toml
 
-source_directory = "/home/example/Pictures/Screenshots"
+[spec.default]
+name = [ "time", "extension" ]
 
-# Host is serving static files at https://example.com:443/sshare/*
+[spec.example]
-# Note: both protocol and port would be optional here as https is
+flag = { short = "e", long = "example" }
-# the default protocol and port 443 is the default https port
+name = [ "preserve", "extension" ]
-[host]
-protocol = "https"
-name = "example.com"
-port = 443
-path = "/sshare"
 
-# Host is listening for ssh connections on port 1234 and
+[spec.noshort]
-# serving files from the `/srv/sshare` directory
+flag = { long = "only" }
-[ssh]
+name = [ "time" ]
-port = 1234
+help = "No short flag, only long flag >:("
-user = "exampleuser2"
-path = "/srv/sshare"
 ```
 
-## Hmmm
+The `spec` section is a collection of different runtime specifications. The name of a specification is
-
+unimportant with the exception of `default`, which is run when no other spec is activated. In each specification
-Apparently GNOME 42 screenshot utility is called via dbus
+that isn't `default`, there is a `flag` attribute that sets which command line arguments activate the
-
+specification. The `flag` attribute must have one or both of `short` or `long`, where `short` will be set the flag
+`-{short}` and `long` will set the flag `--{long}`. The `name` attribute of a specification is an array of name type
+plugins which controls the order in which said plugins are executed. Specifications can also provide a brief description
+in the `help` attribute, which will be displayed when `sshare --help` is run. In the example above,
+running `sshare --help` would give
 ```
-gdbus call
+options:
-	--session
+  -e, --example         Use example spec
-	--dest org.gnome.Shell
+  --only                No short flag, only long flag >:(
-	--object-path /org/gnome/Shell
+```
-	--method org.gnome.Shell.Eval 'Main.screenshotUI.open()'
+#### `config`
-````
-but it cannot be called unless `global.context.unsafe_mode = false`
-is set in gnome shell...which is unideal.
 
-The ideal would be to launch a desired screenshot (or other generative)
+```toml
-utility before running sshare, and for everything that isn't GNOME 42 screenshot,
+[config.ssh]
-I would not expect it to be too hard. But unfortunately I want to use
+host = "example.com"
-GNOME 42 screenshot ;-;
+path = "/directory/to/store/files/in"
+port = 22
+```
 
-What to do...
+The `config` section is used to set configuration options for plugins. Refer to documentation for a plugin to see
+what options can be set here. Documentation for default plugins is included [below](#Default-Plugins).
+
+#### `flags`
+
+```toml
+[flags.file]
+file = { short = "f" }
+
+[flags.stdin]
+stdin = { short = "" }
+
+[flags.example]
+option = { short = "o", long = "ooooption" }
+```
+
+The `flags` section is used to bind plugin arguments to a command line argument. They are specified in the same way
+as the `flag` option for `spec`s. If `long` is left unspecified, the long flag will be set to the default provided by
+the plugin. In the example above, running `sshare --help` would give:
+```
+options:
+  -f file, --file file  Upload a file
+  -, --stdin            Upload from stdin
+  -o xmpl, --ooooption xmpl
+                        This is not a real plugin that exists
+```
+
+### Default Plugins
+
+#### `command_line`
+
+A `logger` plugin which prints to the command line. No configuration needed.
+
+#### `extension`
+
+A `name` plugin which appends the source type to the end of the file name (i.e. `txt`, `png`, etc...). No configuration needed.
+
+#### `file`
+
+A `source` plugin which provides a file to be uploaded. File is specified with the `--file {file_path}` argument. No configuration needed.
+
+#### `preserve`
+
+A `name` plugin which preserves the name of the source in the uploaded file. No configuration needed.
+
+#### `print_location`
+
+A `feedback` plugin which prints the location that sources can be accessed from. No configuration needed.
+
+#### `ssh`
+
+An `upload` plugin which uploads the sources to the server using `ssh`.
+
+##### Configuration
+| Attribute | Type   | Default | Description                                          |

+
+#### `stdin`
+
+A `source` plugin which reads from stdin. No configuration needed.
+
+#### `time`
+
+A `name` plugin which adds the current unix time to the name of the of the uploaded file.
+
+##### Configuration
+| Attribute | Type   | Default | Description                                          |
+|-----------|--------|---------|------------------------------------------------------|
+| format    | int    | 62      | The base between 2 and 62 to represent the number in |
+
+##### `uri`
+
+A `location` plugin which constructs the resulting URI that the uploaded file can be accessed from.
+
+##### Configuration
+| Attribute | Type   | Default | Description                                          |
+|-----------|--------|---------|------------------------------------------------------|
