+ There are various ways in which you can install staticcheck,
+ but they all boil down to obtaining the command located at <code>honnef.co/go/tools/cmd/staticcheck</code>
+</p>
+
+<p>
+ If you use Go modules, you can simply run <code>go get honnef.co/go/tools/cmd/staticcheck</code> to obtain the latest released version.
+ If you're still using a GOPATH-based workflow, then the above command will instead fetch the master branch.
+ It is suggested that you explicitly check out the latest release branch instead, which is currently <code>2019.2</code>.
+ One way of doing so would be as follows:
+</p>
+
+<pre><code>cd $GOPATH/src/honnef.co/go/tools/cmd/staticcheck
+git checkout 2019.2
+go get
+go install
+</code></pre>
+

+ Alternatively, you can <a href="https://github.com/dominikh/go-tools/releases">download pre-compiled binaries from GitHub.</a>
+</p>
+
+<p>
+ If you'd like to be notified of new releases, you can use GitHub's
+ <a href="https://help.github.com/en/articles/watching-and-unwatching-releases-for-a-repository"><em>Releases only</em> watches</a>.
