+## Quickstart
+
+### Dependencies
+
+To install dependencies, after cloning the repository, run:
+
+```bash
+npm ci
+```
+
+### Build
+
+To build the application, run:
+
+```bash
+npm run build
+```
+
+### Usage
+
+To execute the application run:
+
+```bash
+npm start -- -i example.yaml
+```
+
+### Clean
+
+To clean output & build path run:
+
+```bash
+npm run clean
+```
+
+You can find all the options in our [README](./README.md) file
+
+### Putting all together
+
+When you are developing a new feature you must clean output & build path, rebuild the app and execute it. So this is a good command to _remember_:
+
+```bash
+npm run clean && npm start -- -i input/file.yaml
+```
+
 ## Pull request process
 
 1. Ensure any install or build dependencies are solved before doing a build.
