+
+## Development
+
+This repository uses [`just`](https://github.com/casey/just) for
+orchestrating commands. To install, run `cargo install just`. Before
+submitting a PR, update the schema files by running:
+
+```
+just schema
+```
+
+To pass CI, your changes will need to pass the following checks:
+
+```
+just build
+just test
+just lint
+just integration-test
+```
+
+To track gas usage over time and run some tests against a real chain
+we use [de-husk](https://github.com/de-husk)'s
+[cosm-orc](https://github.com/de-husk/cosm-orc) library. To add a
+test, edit or create a file in `ci/integration-tests/src/tests`. Any
+test written in that way will be included in gas measurements. A
+significant deviation in gas usage between two changes for a test will
+cause a comment to be added to the relevant PR.

+# Integration Tests
+
+e2e integration tests with gas profiling.
+
+`cd ci/integration_tests && cargo t` to run all tests.
+
+`cargo t fn_test_name` to run individual integration tests.
+
+## Adding New Integration Tests
+
+Add new tests in `src/tests`:
+```rust
+#[test_context(Chain)]
+#[test]
+#[ignore]
+fn new_dao_has_no_items(chain: &mut Chain) {
+    let res = create_dao(
+        chain,
+        None,
+        "ex_create_dao",
+        chain.users["user1"].account.address.clone(),
+    );
+    let dao = res.unwrap();
+
+    // use the native rust types to interact with the contract
+     let res = chain
+        .orc
+        .query(
+            "cw_core",
+            &cw_core::msg::QueryMsg::GetItem {
+                key: "meme".to_string(),
+            },
+        )
+        .unwrap();
+    let res: GetItemResponse = res.data().unwrap();
+
+    assert_eq!(res.item, None);
+}
+```
+
+We are currentlying [ignoring](https://doc.rust-lang.org/book/ch11-02-running-tests.html#ignoring-some-tests-unless-specifically-requested) all integration tests by adding the `#[ignore]` annotation to them, because we want to skip them when people run `cargo test` from the workspace root.
+
+Run `cargo c` to compile the tests.
