+Verify your `$GOPATH` is correctly set before continuing.
+
+### Setup this Repository
+
+Go is bit picky about where you store your repositories.
+
+The convention is to store:
+- the source code inside the `$GOPATH/src`
+- the compiled program binaries inside the `$GOPATH/bin`
+
+You can `clone` the repository or use `go get` to install it.
+
+#### Using Git
+```bash
+mkdir -p $GOPATH/src/github.com/web3coach
+cd $GOPATH/src/github.com/web3coach
+
+git clone [email protected]:web3coach/the-blockchain-way-of-programming-newsletter-edition.git
+```
+
+PS: Make sure you actually clone it inside the `src/github.com/web3coach` directory, not your own, otherwise it won't compile. Go rules.
+
+#### Using Go Get
+```bash
+go get -u github.com/web3coach/the-blockchain-way-of-programming-newsletter-edition
+```
