Documentation: removed an extra step for testing etcd
removed an extra step for testing etce build that might confuse the user of the flow. minimal editing to the doc
## System requirements
-The etcd performance benchmarks run etcd on 8 vCPU, 16GB RAM, 50GB SSD GCE instances, but any relatively modern machine with low latency storage and a few gigabytes of memory should suffice for most use cases. Applications with large v2 data stores will require more memory than a large v3 data store since data is kept in anonymous memory instead of memory mapped from a file. than For running etcd on a cloud provider, we suggest at least a medium instance on AWS or a standard-1 instance on GCE.

## Test the installation
Check the etcd binary is built correctly by starting etcd and setting a key.
-Start etcd:
+### Starting etcd
+
+If etcd is built without using GOPATH, run the following:
```
$ ./bin/etcd
```
+If etcd is built using GOPATH, run the following:
+
+```
+$ $GOPATH/bin/etcd
