+# Rust Elaborator
+
+This program serves to take a list of boardgames as a csv and return a csv with more data about them.
+
+## Building
+
+### Clone the git repo locally
+
+`git clone https://git.mtgmonkey.net/Andromeda/rust-elaborator.git`
+`cd rust-elaborator`
+
+### Run the sample
+
+`cat sample_in.csv | nix run`
+
+the output `out.csv` should match the provided `sample_out.csv`
+
+## Usage
+
+The program reads a csv from stdin and outputs it to `out.csv`. The following command reads the contents of `in.csv` into the program and runs it.
+
+`cat in.csv | rust_elaborator`
+
+`in.csv` must be formatted as follows...
+
+|title|
+|-|
+|Monopoly|
+|Abomination|
+|7 Wonders|
+|Uno|
+
+...in excel or as follows...
+
+```csv
+title,
+Monopoly,
+Abomination,
+7 Wonders,
+Uno,
+```
+
+...as plaintext
+
+where `title` can be anything.
+Capitalization does not matter.
+Additional columns will not be present in `out.csv`.
