+# Simple CI/CD package for any application
+
+Integrate a simple CI/CD process into your application without the hassle.
+
+_**NOTE:** This package needs `node` installed to work_
+
+## Requirements
+
+-   **Node JS Runtime and NPM:** You need to have `NodeJS` and `npm` installed on the target machine for this package to work.
+-   **`nodecid.config.json` file:** This package depends on a configuration file located in the root directory of your application.
+
+## Installation
+
+To install this package globally just run:
+
+```shell
+npm install -g nodecid
+```
+
+To run the package directly run:
+
+```shell
+npx nodecid
+```
+
+This will download the package and run the binaries directly. After the first run it won't download the package again.
+
+## Usage
+
+To run the package after installing it globally just run:
+
+```shell
+nodecid
+```
+
+Remember you must have a `nodecid.config.json` file located in your root directory else this will throw an error.
+
+### Configuration
+
+Your `nodecid.config.json` file should look like this:
+
+```json
+{
+    "start": "node index.js",
+    "preflight": ["npm run test", "npm run build"]
+}
+```
+
+or
+
+```json
+{
+    "start": "node index.js",
+    "preflight": "./preflight.sh"
+}
+```
+
+Your `preflight` parameter can wither be an array of commands, or path to a shell script. This will run before every `start` commands.
+
+Optionally you could include a `redeploy_path` in your config file:
+
+```json
+{
+    "start": "node index.js",
+    "preflight": "./preflight.sh",
+    "redeploy_path": "./REDEPLOY"
+}
+```
+
+This will look for the file named `REDEPLOY` in your rood directory and watch that file. If the file is changed the application will be restarted, ie it will run the `preflight` command(s) and `start` command. If you ommit the `redeploy_path` a file named `REDEPLOY` will be created in your root directory.
+
+You can change the name and path of the `redeploy_path`, just make sure the path is correct and the file name exists in the named path. Example:
+
+```json
+{
+    "start": "node index.js",
+    "preflight": "./preflight.sh",
+    "redeploy_path": "./deploy/trigger.txt"
+}
+```
+
+_NOTE:_ This also works for other languages, example:
+
+```json
+{
+    "start": "python app.py",
+    "preflight": "./preflight.sh"
+}
+```
+
+This app just runs whatever command you send it in an isolated child process, the command will be run as if being run in a terminal.
+
+### Redeployment
+
+For continuos deployment and integration there needs to be a text file located in your project which the application can watch. Any time the content of this file is changed the application will rebuild and rerun your `start` command.
