+
+### Windows Users
+
+`node-blink1` depends on `node-hid`, a native module that uses `node-gyp` to
+build.  `node-gyp` requires Python 2.7.3 in the PATH, and if you have Python 3
+installed, you may have to modify your PATH for `node-gyp` to locate it.
+
+See [issue #3](https://github.com/sandeepmistry/node-blink1/issues/3) for
+details.
+
+### Linux Users
+
+If you encounter the following error while installing, you'll need new install
+of `libusb`.
+
+```
+libusb.h: No such file or directory compilation terminated.
+```
+
+For Debian and Ubuntu, install the package `libusb-1.0-0.dev`.
+
+See [issue #4](https://github.com/sandeepmistry/node-blink1/issues/4) for
