+# Speakeasy
+
+This package provides cross-platform Go (#golang) helpers for taking user input
+from the terminal while not echoing the input back (similar to `getpasswd`). The
+package uses syscalls to avoid any dependence on cgo, and is therefore
+compatible with cross-compiling.
+
+[![GoDoc](https://godoc.org/github.com/bgentry/speakeasy?status.png)][godoc]
+
+## Unicode
+
+Multi-byte unicode characters work successfully on Mac OS X. On Windows,
+however, this may be problematic (as is UTF in general on Windows). Other
+platforms have not been tested.
+
+## License
+
+The code herein was not written by me, but was compiled from two separate open
+source packages. Unix portions were imported from [gopass][gopass], while
+Windows portions were imported from the [CloudFoundry Go CLI][cf-cli]'s
+[Windows terminal helpers][cf-ui-windows].
+
+The [license for the windows portion](./LICENSE_WINDOWS) has been copied exactly
+from the source (though I attempted to fill in the correct owner in the
+boilerplate copyright notice).
