 # Indivisible
 
-Indivisible is an optimized prime number generator and tester written in Rust.
+Indivisible is an optimized prime number generator and tester.
 
 ## Build & Installation
 
-To build the project you will require the Rust compiler and build
-system, `cargo`. At which point you simply run `cargo build` in the root
-directory of the project. To create an optimized release build append
-the `--release` flag to the previous command.
+Build a binary release using the following command:
 
-Once a release build has been compiled, you may install Indivisible and
-the manpage documentation by running the `install` script. In a similar
-manner, you can run the `uninstall` script to remove the previously
-installed binary and documentation.
+```console
+$ cargo build -r
+```
 
-## Usage
+Once compiled, you can install it using the `install` script. By default this
+will install to `/usr/local/{bin,share}`, but you can optionally change the
+`PREFIX` used as follows:
 
-The purpose of Indivisible is to find the nth prime and all the primes
-before it. The basic usage is `indivisible <n>` where `n` is the ordinal
-of the prime you'd like to find. To display all primes before `n`, you
-can run verbose mode by using the `--verbose` or simply `-v` option.
+```console
+$ PREFIX="~/.local" ./install
+```
 
-Since Indivisible generates primes using previously computed primes, you
-can also import prime numbers previously computed with the `--import` or
-`-i` option. To store already computed primes you are expected to use
-piping like any UNIX user would expect. Here is an example:
+Additionally there is an `uninstall` script available. If you have used a custom
+`PREFIX` this must also be specified to uninstall in the same manner. To see
+where you've installed it you can always use the following command:
 
-```bash
-# store first 100 primes in ./primes
-indivisible -v 100 > ./primes
-# appends next 400 primes
-indivisible -i ./primes -v 500 >> ./primes
-# display the 600th prime
-indivisible -i ./primes 600
+```console
+$ which indivisible
 ```
