-This Rust project is designed to extract command-line flags from input and generate a powerset of those flags up to a specified depth. The resulting subsets are then prefixed with a constant string and printed to the console.
+Powerset is a simple Rust binary (and perhaps future library), that takes a
+configuration file specifying commands and uses it to produce a powerset of
+those commands. This helps easily generate tests from a single source of truth,
+allowing your tests to be initialized at any time from the declarative
+configuration.
 
-## Features
+Historically, it would parse the output of a binary via a regex. Currently,
+it's being refactored to generate configurations from this parsing, but
+primarily being dependent on the actual configuration first and foremost.
 
-    Extract short (-f) and long (--flag) command-line flags from input.
-    Generate a powerset of the extracted flags up to a specified depth.
-    Prefix each subset in the powerset with a constant string (eza by default).
+This program was created for eza, but eventually, it should be usable more
+broadly.
 
 ## Usage
 
@@ -18,24 +23,6 @@ Compile the Rust program:
 ```bash
 cargo build --release
 ```
-Run the compiled binary and provide the input:
-
-```bash
-echo "-a, --all... -l, --long..." | ./target/release/your_binary_name
-```
-
-Replace `your_binary_name` with the appropriate name of your compiled binary.
-
-The program will print the output strings, each prefixed with the constant string and containing a subset of the extracted flags.
-
-# Configuration
-
-    `DEPTH`: Adjust this constant to set the maximum size of the subsets in the powerset. Default is `2`.
-    `BINARY`: This constant string is prefixed to each subset in the powerset. Default is `eza`.
-
-# Dependencies
-
-    `regex`: This crate is used for extracting flags from the input using regular expressions.
