-## Zombienet Testing
-
-Zombienet is used to launch a complete network including a relay chain, and two parachains. It will create HRMP channels betweens the launched parachains allowing the testing environment to send XCM messages and transfer assets.
-
-### **Requirements**:
-
-**Zombienet Binary**: You can download the appropriate binary from the zombienet repository [here](https://github.com/paritytech/zombienet/releases). Ensure that it is in the root of this directory. Note: For macos users if permission is denied to run the binary you can `chmod 755 <file_name>` to allow permissions.
-
-**Test Network Binaries**: You will need the following binaries depending on whether you want to run a small or medium network:
-
-- polkadot: You can find the releases [here](https://github.com/paritytech/polkadot-sdk/releases). (Needed for small, or medium network)
-- trappist-collator: This binary is compiled along with polkadot above. You can find it [here](https://github.com/paritytech/trappist). (Needed for medium network)
-- polkadot-parachain (ie: cumulus): You can find the releases [here](https://github.com/paritytech/polkadot-sdk/releases). (Needed for small, or medium network)
-
-NOTES:
-
-- When it comes to picking a version for both `cumulus` and `polkadot` ensure they are the same. Cumulus will have an extra 0 at the end though. Ex: v0.9.37 (polkadot) -> v0.9.370 (cumulus)
-
-- You can retrieve the binaries via the release, or by compiling yourself. It's recommended to compile it yourself.
-
-Copy each binary that is necessary into the root `<root>/bin` folder.
-
-### Running Zombienet
-
-From the root directory run `./<zombienet_binary_name> -p native spawn ./zombienet/<network_file>.toml | tee zombienet.log`
-
-### Create an asset
+## E2E Testing
 
-From the root directory run `yarn start:zombienet-post-script`. You can run this right after running your zombienet network.
+You can access the E2E tests and their documentation [here](./e2e-tests/).

 ## E2E Tests
 
-End-to-end tests that run on a zombienet testnet.
+End-to-End tests that run using Chopsticks.
 
-**NOTE: tested using polkadot v1.4.0**
-
-### Setup
-
-To setup the testing environment you need to first download the `polkadot`, `polkadot-execute-worker`, `polkadot-prepare-worker` and `polkadot-parachain` from the `polkadot-sdk` [release page](https://github.com/paritytech/polkadot-sdk/releases/latest), as well as the `trappist-node` from its [release page](https://github.com/paritytech/trappist/releases/latest), and place them in the `../zombienet/bin/` folder.
-
-You also need to have the latest `zombienet` executable in the `../zombienet/` folder, which you can download from [here](https://github.com/paritytech/zombienet/releases/latest).
-
-### Launching zombienet
-
-To launch the zombienet run the following commands:
+To run the end-to-end tests run the command:
 
 ```bash
-$ yarn build && yarn e2e:build
+$ yarn build && yarn build:e2e
 ```
 
 Then run:
 
 ```bash
-$ yarn e2e:zombienet
+$ yarn test:e2e
 ```
-
-And this will launch the zombienet using the config file located in the `../zombienet/` directory. Once it finished its setup, you can proceed to the following step.
-
-### Launching the tests
-
-For testing, we provide 4 options:
-
-- Testing liquidity tokens transfers with the command `yarn e2e:liquidity-assets`.
-- Testing foreign assets transfers with the command `yarn e2e:foreign-assets`.
-- Testing local transferss with the command `yarn e2e:local`.
-- Testing assets transfers with the command `yarn e2e:assets`.
-
-Each of these commands will run the appropiate script to setup the basics, located in `../scripts/`. Wait for it to finish setting up the testing environment, and then go through the tests indicated in the `./tests/index.ts` file for the chosen option.
-
-After each testing suite has been completed, it's recommended to restart the zombienet before running another test suite.
