+# Manta's zombienet examples
+
+## Docs and examples
+- docs: https://paritytech.github.io/zombienet/
+- examples: 
+    - https://github.com/paritytech/zombienet/tree/main/examples
+    - https://github.com/paritytech/cumulus/tree/master/zombienet
+    - https://github.com/paritytech/polkadot/tree/master/zombienet_tests
+
+## Install zombienet
+
+According to your platform, download the latest pre-compiled binary from [zombinet](https://github.com/paritytech/zombienet/releases) repository.
+
+## Start network
+
+### Start one paracahin network locally by zombienet
+1. Go to [small-network](./small-network.toml), make the `command` point to the polkadot binary and manta binary.
+2. Start the network.
+    ```shell
+    zombienet spawn --provider native small-network.toml
+    ```
+    After a while, the network will be started.
+
+### Start two parachains
+1. Go to [two-parachains](./two-parachains.toml), make the `command` point to the polkadot binary and manta binary.
+2. Start the network.
+    ```shell
+    zombienet spawn --provider native two-parachains.toml
+    ```
+    After a while, two paracahins(`2084` and `2104`) will be started.
+
+## Testing
+
+Zombienet supports testing as well, but you have to write test cases with a special dsl: `zndsl`. 
+Please take a look at this [doc](https://paritytech.github.io/zombienet/cli/test-dsl-definition-spec.html) to see more details about how to write test cases.
+
+### Runtime upgrade(not ready)
+1. Go to [runtime-upgrade](./runtime-upgrade.toml), make the `command` point to the polkadot binary and manta binary. And go to [runtime upgrade test case](./runtime-upgrade.zndsl), make sure `line 6` point to the correct wasm binary.
+2. Run runtime upgrade.
+    ```shell
+    zombienet -f --provider native test runtime-upgrade.zndsl
+    ```
+    This test case would take minutes to be finished.
+
+### Run you own customized test script
+1. Go to [custom-script](./custom-script.toml), make the `command` point to the polkadot binary and manta binary. 
+2. Define and implement a function named `run` in your script.
+    ```ts
+    async function run(nodeName, networkInfo, args) {
+        return 2084;
+    }
+    ```
+3. Go to the [custom-script test case](./custom-script.zndsl), make sure `line 8` point to your script, and compare the expected value.
+    ```
+    Dave: js-script ./custom-script.js return is equal to 2084 within 300 seconds
+    ```
+4. Start the test.
+    ```shell
+    zombienet -f --provider native test custom-script.zndsl
+    ```
+
+## Tips:
+1. When run the network, please do not use the same node name for relaychain and parachain.
+For example: if one relaychain node takes `Alice`, so you cannot use `Alice` for any parachain nodes, but you can use `alice`.
+2. Please be careful the node name in your test case, you must understand what you want to test.
+For example, if one relaychain node takes `Alice` as node, you can use `alice` for one of paracahin nodes, the `Alice` will test relaychain node, but `alice` is for parachain only.
+    ```
+    alice: parachain 2084 is registered within 225 seconds
+    Alice: reports block height is at least 5 within 250 seconds
+    ```
+    The first line will check parachain's block production, the second line will check relaychain's.
+    Because relaychain and parachain use the same node name, the zombienet's test framework won't know who is `Alice`.
