 This is similiar to using a .tfswitchrc file, but you can specify a custom binary path for your terraform installation

 2. Add the path to your PATH. Ex: `export PATH=$PATH:/Users/warrenveerasingam/bin` (add this to your bash profile or zsh profile)
 3. Pass -b or --bin parameter with your custom path to install terraform. Ex: `tfswitch -b /Users/warrenveerasingam/bin/terraform 0.10.8 `

+4. Optionally, you can create a `.tfswitch.toml` file in your terraform directory(current directory) OR in your home directory(~/.tfswitch.toml). The toml file in the current directory has a higher precedence than toml file in the home directory

-```
