After building or unpacking Horizon, you simply need to copy the native binary into a directory that is part of your PATH. Most unix-like systems have /usr/local/bin in PATH by default, so unless you have a preference or know better, we recommend you copy the binary there.
To test the installation, simply run horizon --help from a terminal. If the help for Horizon is displayed, your installation was successful. Note: some shells, such as zsh, cache PATH lookups. You may need to clear your cache (by using rehash in zsh, for example) before trying to run horizon --help.
Should you decide not to use one of our prebuilt releases, you may instead build Horizon from source. To do so, you need to install some developer tools:
A unix-like operating system with the common core commands (cp, tar, mkdir, bash, etc.)
A compatible distribution of Go (Go 1.13 or later)
