 1. Use the Go tools to install Hound. The binaries `houndd` (server) and `hound` (cli) will be installed in your $GOPATH/bin directory. Your $GOPATH should be in your $PATH (`echo $PATH` to check).
 
+  ```
+  go get github.com/hound-search/hound/cmds/...
+  ```
 
-```
-go get github.com/hound-search/hound/cmds/...
-```
+  If the above doesn't work for you, try to install hound manually with the following:
+
+  ```
+  git clone https://github.com/hound-search/hound.git
+  cd hound
+  go build ./cmds/hound
+  go build ./cmds/houndd
+  sudo mv hound houndd ~/go/bin/
+  ```
+
+  You might have to change the path of the last command if you installed Go somewhere else on your system.

+2. Create a config.json file in your `$GOPATH/bin` and use it to list your repositories. Check out our [example-config.json](config-example.json)
 to see how to set up various types of repositories. For example, we can configure Hound to search its own source code using 
 the config found in [default-config.json](default-config.json):
 
-```json
-{
-  "dbpath" : "db",
-  "repos" : {
-    "Hound" : { "url" : "https://github.com/etsy/hound.git" }
+  ```json
