If the MD5 code is inconsistent with the installation package's MD5 code displayed on the official website, although the installation is successful, there is the possibility that the installation file is tampered with!

# Installation Fail

Execute topio -v in any directory to verify whether the installation was successful.

If the following is output, the installation is failed.

-bash: topio: command not found

If the installation fails, please redo the installation steps.

# Configure Environment Variables (optional)

After TOPIO is installed, configure environment variables with the following command, to set "/opt/topnetwork" to your authority directory.

echo "export TOPIO_HOME=/opt/topnetwork" >> ~/.bashrc && source ~/.bashrc

If you do not configure environment variables, you will use the system default directory as the working directory of TOPIO:

root user: the default directory is "/root/topnetwork";

For non-root users: the default directory is "/home/user/topnetwork", where "user" is your user name to log in to the server.
