 `realize` watches the directory for changes and rebuilds the cli whenever a new
 change happens. The cli is installed to `$GOPATH/bin/hasura`, which should
 already be in your `PATH`. The config is located at `.realize/realize.yaml`.
+
+## Tests
+
+When you're adding a new feature, it is encouraged to add integration tests (unit tests also if possible) for the functions/api. You should run all the test and make sure everything passes before submitting the PR.
+
+The tests expect a GraphQL Engine server instance to be running. You can point the tests to any GraphQL Engine server but please note that **the database should be empty**. The easiest way to do this is to run an Postgres and GraphQL Engine using [Docker Compose](https://github.com/hasura/graphql-engine-install-manifests). Once the server is running, you can run the tests by executing the make command:
+
+```bash
+HASURA_GRAPHQL_TEST_ENDPOINT=http://localhost:8080 make test
+```
+
+## Builds
+
+To build a binary, execute the following command:
+
+```bash
+# make deps to install all go packages
+make build
+```
+
+This will output cross-platform binaries to `_output` directory.
