+
+## Installation
+
+```
+npm install is-ci --save
+```
+
+## Programmatic Usage
+
+```js
+const isCI = require('is-ci')
+
+if (isCI) {
+  console.log('The code is running on a CI server')
+}
+```
+
+## CLI Usage
+
+For CLI usage you need to have the `is-ci` executable in your `PATH`.
+There's a few ways to do that:
+
+- Either install the module globally using `npm install is-ci -g`
+- Or add the module as a dependency to your app in which case it can be
+  used inside your package.json scripts as is
+- Or provide the full path to the executable, e.g.
+  `./node_modules/.bin/is-ci`
+
+```
+is-ci && echo "This is a CI server"
+```
+
