+# stub.sh [![Build Status](https://api.travis-ci.org/jimeh/stub.sh.svg)](https://travis-ci.org/jimeh/stub.sh)
 
-A set of stubbing helpers for use in bash script tests. Supports stubbing and
+Helpers for bash script testing to stub/fake binaries and functions. Includes
-restoring both binaries and bash functions.
+support for validating number of stub calls, and/or if stub has been called
+with specific arguments.
 
 Particularly useful when used in combination with the simple and elegant
 [assert.sh](https://github.com/lehmannro/assert.sh) test framework.
 
+## Installation
+
+The `stub.sh` script can be installed in several ways:
+
+- Downloading the "raw" `stub.sh` file from Github
+- Using `bpkg`
+
+### Downloading the `stub.sh` file
+
+```sh
+curl -LO 'https://github.com/jimeh/stub.sh/raw/master/stub.sh'
+```
+
+(Or manually open https://github.com/jimeh/stub.sh/raw/master/stub.sh in a webbrowser).
+
+### Using bpkg
+
+[BPKG](http://www.bpkg.io/) is a lightweight package manager for bash.
+
+`stub.sh` is available as [bpkg](http://www.bpkg.io/) package:
+
+```sh
+bpkg install jimeh/stub.sh
+```
+
+This will install `stub.sh` at `./deps/stub.sh/stub.sh` in the directory that `bpkg` has been run in.
+
+To install globally run: `bpkg install -g jimeh/stub.sh`
