+# Install hummingbot
+
+## 1. Environment
+
+- OS: Ubuntu 22.04
+- hummingbot: v1.13.0
+
+## 2. Install dependencies
+
+```shell
+sudo apt update -y
+sudo apt install -y build-essential curl git httpie jq wget
+```
+
+## 3. Install Miniconda3
+
+```shell
+cd ${HOME}
+wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
+chmod +x Miniconda3-latest-Linux-x86_64.sh
+./Miniconda3-latest-Linux-x86_64.sh -b -u
+./miniconda3/bin/conda init
+# Reload .bashrc to register "conda" command
+exec bash
+conda install -y conda-build
+```
+
+## 4. Install client
+
+### 4.1 Install client
+
+```shell
+cd ${HOME}
+git clone https://github.com/Carry-So/hummingbot.git
+cd hummingbot
+git checkout xdc-release-1.13.0
+./clean
+./install
+conda activate hummingbot

+```
+
+### 4.2 Start client
+
+Start hummingbot by run command:
+
+```shell
+cd ${HOME}/hummingbot
+bin/hummingbot.py
+```
+
+Setup your password when first login, refer to https://docs.hummingbot.org/operation/password/#creating-a-password.
+
+### 4.3 generate certificates
+
+Then run command `gateway generate-certs` in the input panel to generate self-signed certificates, refer to https://docs.hummingbot.org/gateway/installation/#generate-certs.

+
+## 5. Install gateway
+
+### 5.1 Install gateway
+
+```shell
+cd ${HOME}
+git clone https://github.com/Carry-So/hummingbot-gateway.git
+cd hummingbot-gateway
+git checkout xdc-release-1.13.0
+
+# Install dependencies
+yarn
+
+# Complile Typescript into Javascript
+yarn build
+```
+
+### 5.2 Setup gateway
+
+Run Gateway setup script, which helps you set configs and certificates:
+
+```shell
+cd ${HOME}/hummingbot
+./gateway-setup.sh
+```
+
+Below is the interactive process:
+
+```text
+===============  SETUP GATEWAY ===============
+
+
+Enter path to the Hummingbot certs folder >>> /home/liudan/hummingbot/certs
+
+   Confirm if this is correct:
+
+            Copy configs FROM: /home/liudan/hummingbot-gateway/src/templates
+              Copy configs TO: /home/liudan/hummingbot-gateway/conf
+
+              Copy certs FROM: /home/liudan/hummingbot/certs
+                Copy certs TO: /home/liudan/hummingbot-gateway/certs
+
+Do you want to proceed? [Y/N] >>> Y
+
+Files successfully copied from /home/liudan/hummingbot-gateway/src/templates to /home/liudan/hummingbot-gateway/conf
+
+Files successfully copied from /home/liudan/hummingbot/certs to /home/liudan/hummingbot-gateway/certs
+```
+
+### 5.3 Start gateway
+
+Start gateway using passphrase:
+
+```shell
+cd ${HOME}/hummingbot-gateway
+# yarn start --passphrase=daniel
+yarn start --passphrase=<passphrase>
+```
+
+### 5.4 Test connection
+
+The client should show: `Gateway: ONLINE` on the top of log pane(right) now. Run the command `gateway test-connection` in Hummingbot to test the connection. Now, you can type command `exit` in client to quit now. When you exit and restart client, it should automatically detect whether gateway is running and connect to it.

+- I created some test tokens on apothem blockchain with [factory contract 0xfD9F33ab143b1717D4784A420eE5A93A8CbBcABd](https://explorer.apothem.network/address/xdcfD9F33ab143b1717D4784A420eE5A93A8CbBcABd#readContract). Pleas mint enough test tokes to your test account on blockchain explorer.

+# Test xsswap exchange
+
+Test hummingbot gateway API with [xsswap exchange](https://app.xspswap.finance/pool)
+
+## Preparations
+
+### 1. Setup enviroment
+
+Setup enviroment according to [instructions](./setup-test-enviroment.md) before test.
+
+### 2. Trade pools
+
+I created some trade pools on xsswap and testnet:
+
+| Token1 | Token2 | Price(Token1/Token2) |
+| -----: | -----: | -------------------: |
+|  WBTC2 |  USDC2 |                20000 |
+|   YFI2 |  USDC2 |                 8000 |
+|   MKR2 |  USDC2 |                  600 |
+|  AAVE2 |  USDC2 |                   70 |
+|   UNI2 |  USDC2 |                    5 |
