+
+#### Install Dependencies 
+
+```bash
+yarn 
+```
+
+#### Build the lib
+```bash
+yarn build
+```
 
+#### Link the lib to an ESM that depends on this lib (i.e: openmrs-esm-form-builder)
+```bash
+cd path/to/openmrs-esm-form-builder
+
+yarn link path/to/openmrs-form-engine-lib
+```
+
+*The linking is what allows you to see your changes locally.*
+
+#### Start the dependant ESM locally as you would normally do 
+```bash
+yarn start
+```
