 ## Usage
 
 ```toml
 [dependencies]
-minstant = "0.1"
+fastant = "0.1"
 ```
 
 ```rust
-let start = minstant::Instant::now();
-
-// Code snipppet to measure
-
-let duration: std::time::Duration = start.elapsed();
+fn main() {
+    let start = fastant::Instant::now();
+    let duration: std::time::Duration = start.elapsed();
+}
 ```
 
-
 ## Motivation
 
-This library is used by a high performance tracing library [`minitrace-rust`](https://github.com/tikv/minitrace-rust). The main purpose is to use [TSC](https://en.wikipedia.org/wiki/Time_Stamp_Counter) on x86 processors to measure time at high speed without losing much accuracy.

 ## Platform Support
 
-Currently, only the Linux on `x86` or `x86_64` is backed by [TSC](https://en.wikipedia.org/wiki/Time_Stamp_Counter). On other platforms, `minstant` falls back to `std::time`. If TSC is unstable, it will also fall back to `std::time`.
+Currently, only the Linux on `x86` or `x86_64` is backed by Time Stamp Counter (TSC). On other platforms, Fastant falls back to `std::time`. If TSC is unstable, it will also fall back to `std::time`.
 
 If speed is privileged over accuracy when fallback occurs, you can use `fallback-coarse` feature to use coarse time:
 
 ```toml
 [dependencies]
-minstant = { version = "0.1", features = ["fallback-coarse"] }
-```

-Benchmark platform is `Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz` on CentOS 7.
