+# Find Executables Installed By Go
+
+When you install an executable using `go install`, it puts that executable in
+the `bin` directory designated by the `GOBIN` environment variable. If that env
+var isn't set, then it falls back to one of `$GOPATH/bin` or `$HOME/go/bin`.
+
+When I run `go help install`, it tells me as much:
+
+```
+Executables are installed in the directory named by the GOBIN environment
+variable, which defaults to $GOPATH/bin or $HOME/go/bin if the GOPATH
+environment variable is not set.
+```
+
+So, if I am to install something like [`tern`](https://github.com/jackc/tern),
+
+```bash
+$ go install github.com/jackc/tern/v2@latest
+```
+
+it is going to place that binary in `~/go/bin` for me.
+
+```bash
+$ which tern
+/Users/jbranchaud/go/bin/tern
+```
