+# Using Kapitan to generate Terraform configuration
+
+kapitan can be used to generate `*.tf.json` with jsonnet and jinja2.
+
+Running `kapitan compile` in this directory would produce 3 terraform projects named `project1`, `project2`, and `project3`:
+
+```
+$ docker run -t --rm -v $(pwd):/src:delegated deepmind/kapitan compile
+Compiled project3 (0.32s)
+Compiled project1 (0.39s)
+Compiled project2 (0.41s)
+
+$ tree compiled
+compiled
+├── project1
+│   └── manifests
+│       ├── dns.tf.json
+│       ├── output.tf.json
+│       └── provider.tf.json
+├── project2
+│   └── manifests
+│       ├── container.tf.json
+│       ├── output.tf.json
+│       └── provider.tf.json
+└── project3
+    └── manifests
+        ├── container.tf.json
+        ├── output.tf.json
+        └── provider.tf.json
+
+6 directories, 9 files
+```
+
+You can now run `terraform` commands as usual:
+
+```
+$ cd compiled/project1/manifests
+
+$ terraform init
+$ terraform plan
+$ terraform apply
+```
