 You can install `hrp` with one shell command, which will download the latest version's released binary and install to the current system.
 
 ```bash
-$ curl -sL https://raw.githubusercontent.com/httprunner/hrp/main/cli/scripts/install.sh | bash
+# install via curl
+$ bash -c "$(curl -ksSL https://raw.githubusercontent.com/httprunner/hrp/main/cli/scripts/install.sh)"
+# install via wget
+$ bash -c "$(wget https://raw.githubusercontent.com/httprunner/hrp/main/cli/scripts/install.sh -O -)"
 ```
 
 If you are a golang developer, you can also install `hrp` with `go get`.
