+# Static binary 
+
+Linux and Windows (WSL2) users can get the static binary [here][staticbin]. If you choose to use the static binary instead of installing through Nix (see [[install]]), note the following:
+
+- You will have to *manually* install the runtime dependencies such as `fzf`, `bat`, `envsubst`, etc. yourself.
+- The static binary corresponds to the last stable release, which generally lags behind the development version (which the Nix install at [[install]] method uses).
