+## Required software
+
+* Terraform (tested on v0.12.24)
+* gcloud CLI
+* Docker (with daemon running)
+
+```
+Terraform v0.12.24
+
+Google Cloud SDK 290.0.1
+alpha 2019.05.17
+beta 2019.05.17
+core 2020.04.24
+```
+
+## Setup
+
+1. Authorize in gcloud CLI.
+
+This projects aims to allow as easy as possible setup. Default application login is not recommended for production use.
+
+```
+gcloud auth login
+gcloud config set account
+gcloud auth application-default login
+```
+
+2. Run make. While terraform is running, you will be asked to confirm applying changes. Answer wih `yes`.
+
+```bash
+make
+```
+
+3. Make sure you enable `Email/Password` authentication provider in Firebase as described in the `make` output.
+
+a. Open FireBase console: https://console.firebase.google.com
+b. Choose `Wild Workouts` project
+c. Go to `Authentication`
+d. Choose `Sign-in method` tab
+e. Click on `Email/Password`, switch to `Enabled` and click `Save`.
+
+## Cloud builds
+
+Go to https://console.cloud.google.com/cloud-build/builds to see your recent builds.
+
+## Destroy
+
+If you want to tear down the project, run `make destroy`.
+
+If you want to create it again, make sure to:
+* Use different project name.
+* Remove `terraform.tfstate` file.
