+
+### Files
+
+These are the files / directories that are created and/or modified with this
+install:
+
+```text
+~/.config/envman/PATH.env
+~/.local/bin/xsv
+~/.local/opt/xsv
+```
+
+## Cheat Sheet
+
+> `xsv` is a command line program for manipulating CSV files. It offers a range
+> of functionalities including slicing, joining, indexing and more. Designed for
+> simplicity and speed, it is an essential tool for anyone working with CSV
+> data.
+
+### Basic Usage
+
+To count the number of rows in a CSV file:
+
+```sh
+xsv count data.csv
+```
+
+### Joining Two CSV Files
+
+To perform an inner join on two CSV files based on a common column:
+
+```sh
+xsv join column1 file1.csv column2 file2.csv
+```
+
+### Sample Data
+
+To randomly sample rows from a CSV file:
+
+```sh
+xsv sample 100 data.csv
+```
+
+### Analyzing Data
+
+To display basic statistics for each column in a CSV file:
+
+```sh
+xsv stats data.csv
+```
