+  instructions](docs/INSTALL.md).
   
-  * **Go:** Installation instructions can be found [here](http://golang.org/doc/install). 
-  
-    It is recommended to add `$GOPATH/bin` to your `PATH` at this point.
-    **Note:** If you are building with `Go 1.5`, then you'll need to 
-    enable the vendor experiment by setting the `GO15VENDOREXPERIMENT` 
-    environment variable to `1`. If you're using `Go 1.6` or later, then
-    it is safe to skip this step.

-  * **Glide:** This project uses `Glide` to manage dependencies as well 
-    as to provide *reproducible builds*. To install `Glide`, execute the
-    following command (assumes you already have Go properly installed):
-    ```
-    $ go get -u github.com/Masterminds/glide
-    ```
-  * **btcd:** This project currently requires `btcd` with segwit support,
-    which is not yet merged into the master branch. Instead,
-    [roasbeef](https://github.com/roasbeef/btcd) maintains a fork with his
-    segwit implementation applied. To install, please see 
-    [the installation instructions](docs/INSTALL.md).
