-##### OpenSSL
-
-To build go-ipfs with OpenSSL support, append `GOTAGS=openssl` to your `make` invocation. Building with OpenSSL should significantly reduce the background CPU usage on nodes that frequently make or receive new connections.
-
-Note: OpenSSL requires CGO support and, by default, CGO is disabled when cross-compiling. To cross-compile with OpenSSL support, you must:
-
-1. Install a compiler toolchain for the target platform.
-2. Set the `CGO_ENABLED=1` environment variable.
-
 #### Troubleshooting
 
 - Separate [instructions are available for building on Windows](docs/windows.md).
