 ## Usage
 
-TODO - this needs to be done sometime...
+As it currently stands, you should only need to run a simple `salt-formula-manager.py` in a directory containing your SFM configuration. There are plans to 1) add a "system-wide" or "default" configuration path, so you do not need to be in a specific directory to run this, and 2) to add a `-c /path/to/config.yaml` parameter to override the default path to the configuration file.
 
 ## Configuration
 
-TODO - this needs to be done sometime...
+Here's an explanation of the current list of configuration parameters...
+
+#### `formulas_url`
+
+Defines the default remote URL to use for Salt formulas. The default here is a common repository (https://github.com/SaltStack-Formulas) that, theoretically, most of your formulas will share.
+
+#### `formulas_dir`
+
+This defines where your formulas are going to be stored. This can be the same directory as your locally-written Salt states, or this can be an entirely separate directory altogether (Note: you WILL need to have permission to write to this directory).
+
+#### `purge_formulas`
+
+If true, SFM will attempt to remove all of the "unmanaged" Salt formulas that are present in the directory defined by `formulas_dir` (noted above).
+
+#### `formulas`
+
+This is just a simple hash/list of formulas to download/manage. Simply giving an array entry (e.g. `- munin` - note there is no colon), or an empty hash (e.g. `- munin: {}`) will let SFM attempt to guess the URL and destination directory. 
+
+#### Formula definitions
+
+Each formula listed (as noted above) has specific options that may be set to change the default.
+
+#### `url`
+
+The remote URL to use - theoretically, this should work with SSH URLs if you have permission to clone over SSH, otherwise, HTTPS URLs will work just fine if you have permission to access the repository.
+
+#### `git_branch`
+
+This defines a specific Git branch to track for changes, if the formula is not on said branch, SFM will attempt to checkout the desired branch.
+
+#### `name`
+
+This option is not very important - if the URL isn't specified for a formula, then SFM will attempt to guess the formula's repository URL based off of the default repository URL and the name/title of the formula. If the name isn't specified, SFM will use the title of the title of the entry appended with "-formula" as its name. Thus, a name of "munin-form" with the default URL "https://github.com/SaltStack-Formulas" when end up with "https://github.com/SaltStack-Formula/munin-form"
+
+**Note:** I'm debating removing this in a future release, as I don't see the use beyond saving a few characters here and there.
