-Building without OpenSSL support (that is, without indistinguishable TLS support) requires no extra steps. 
-To compile with OpenSSL support, follow these steps:
-
-1. You must have [Homebrew](http://brew.sh/) installed.
-
-2. `brew install openssl pkg-config`
-
-3. Find out where Homebrew put the `pkgconfig` files for OpenSSL -- the location depends on your Homebrew installation. Run this command:
-
-   ```
-   $ brew info openssl
-   ```
-   
-   Make note of the "build variable" path for `PKG_CONFIG_PATH`.
-   
-4. Set `PKG_CONFIG_PATH=<path discovered above>` when building, and provide the `-tags OPENSSL` flag. 
-   This can be easily done on the build command line like so:
-
-   ```
-   $ PKG_CONFIG_PATH=<path discovered above> go build -tags OPENSSL
-   ```
