-# ms
+# @prsm/ms
 
 [![NPM version](https://img.shields.io/npm/v/@prsm/ms?color=a1b858&label=)](https://www.npmjs.com/package/@prsm/ms)
 
-Confusingly, not just for converting milliseconds.
+A lightweight utility for parsing and converting time strings to milliseconds and other time units.
+
+## Installation
+
+```bash
+npm install @prsm/ms
+# or
+yarn add @prsm/ms
+# or
+pnpm add @prsm/ms
+```
+
+## Usage
+
+### Basic Usage
 
 ```typescript
 import ms from "@prsm/ms";
 
+// Convert complex time expressions to milliseconds
+ms("1day 2hrs 30min"); // 95400000
+ms("15mins 12s"); // 912000
+ms("1w 3d 12h"); // 907200000
+
+// Negative values
+ms("-30min"); // -1800000
+
+// Numbers are passed through
 ms(100); // 100
-ms("100"); // 100
 
-ms("10s"); // 10_000
-ms("10sec"); // 10_000
-ms("10secs"); // 10_000
-ms("10second"); // 10_000
-ms("10,000,000seconds"); // 10_000_000_000
+// Format flexibility
+ms("1,000 seconds"); // 1000000
+ms("2_000ms"); // 2000
+```
 
-ms("0h"); // 0
+### Options
+
+```typescript
+// Disable rounding (default: true)
 ms("10.9ms"); // 11
 ms("10.9ms", { round: false }); // 10.9
 
-ms("1000.9ms", { round: false, unit: "s" }); // 1.0009
+// Convert to different units (default: "ms")
 ms("1000.9ms", { unit: "s" }); // 1
-
-// All supported unit aliases:
-// ms, msec, msecs, millisec, milliseconds
-// s, sec, secs, second, seconds
-// m, min, mins, minute, minutes
-// h, hr, hrs, hour, hours
-// d, day, days
-// w, wk, wks, week, weeks
+ms("1000.9ms", { round: false, unit: "s" }); // 1.0009
+ms("60s", { unit: "m" }); // 1
+ms("60m", { unit: "h" }); // 1
 ```
+
+### Unit Conversion
+
+```typescript
+// Convert between different time units
+ms("1h", { unit: "ms" }); // 3600000
+ms("90min", { unit: "h" }); // 1.5
+ms("1d", { unit: "h" }); // 24
+ms("1w", { unit: "d" }); // 7
+
+// Precision control
+ms("90.5min", { unit: "h" }); // 2 (rounded by default)
+ms("90.5min", { unit: "h", round: false }); // 1.5083333333333333
+```
+
+### Default Values
+
+```typescript
+// Provide default values for invalid inputs
+ms("", 500); // 500
+ms(null, "1s"); // 1000
+ms("invalid", "5m"); // 300000
+```
+
