+# Build Process
+
+## Build Configurations
+
+The project is configured to create 3 different variations of the app:
+* Development - the app that can be run on the developer's simulator or a development device, it's using the staging environment.
+* Staging - the app that is available in TestFlight and that is using the staging backend environment.
+* Production - the app that is available in TestFlight and that is using the production backend environment.
+
+## Continuous Integration
+
+The CI pipelines are configured in the `Jenkinsfile`. 
+
+There are 2 kinds of builds: a test build and archive build.
+
+### Test Build
+
+The test build runs all of the Unit Tests using the Staging environment. 
+The build is triggerred for every pull request push event.
+The script for this build is in the `bin/test.sh`.
+During the unit test, the coverage report is collected and uploaded to the codecov.io tool's website.
+
+### Archive Build
+
+The archive build produces the app in Staging and Production configurations and uploads them to the TestFlight (App Store). 
+The archive build runs when a pull request is merged to the `main` or `release/*` branch.
+The script for this build is in the `bin/archive.sh`.
