+# Building Nighthawk
+
+While GetNighthawk distribution are a convenient way of using Nighthawk, you can also build Nighthawk and run it from source.
+
+## Clone the Nighthawk repo
+
+Using GitHub CLI:
+
+```
+gh repo clone envoyproxy/nighthawk
+```
+
+Using HTTPS:
+
+```
+git clone https://github.com/envoyproxy/nighthawk.git
+```
+
+## Install Dependencies
+
+On Ubuntu, run the following:
+
+```console
+sudo apt-get install \
+    autoconf \
+    automake \
+    cmake \
+    curl \
+    libtool \
+    make \
+    ninja-build \
+    patch \
+    python3-pip \
+    unzip \
+    virtualenv
+```
+
+Install [Golang](https://golang.org/) on your machine. This is required as part of building [BoringSSL](https://boringssl.googlesource.com/boringssl/+/HEAD/BUILDING.md) and also for [Buildifer](https://github.com/bazelbuild/buildtools) which is used for formatting bazel BUILD files.
+
+## Building Nighthawk
+
+Run:
+
+```
+bazel build -c opt //:nighthawk
+```

+title: Running Performance Tests

+
+[Meshery](https://meshery.io/) uses Nighthawk as one of its load generators to run performance benchmarking. Meshery is the canonical implementation of [Service Mesh Performance](https://smp-spec.io/), CNCF's service mesh performance benchmarking specification.
+
+# Performance Benchmarking Using mesheryctl
+
+`mesheryctl` is the command line interface of Meshery. `mesheryctl` along with other load generators,  `mesheryctl` can use Nighthawk to run performance benchmarks.
+
+
+## Install mesheryctl
+
+Check this [quick start guide](https://meshery.io/#getting-started) on how to install mesheryctl.
+
+```
+mesheryctl -h
+```
+
+```
+Meshery is the service mesh management plane, providing lifecycle, performance, and configuration management of service meshes and their workloads.
+
+Usage:
+  mesheryctl [command]
+
+Available Commands:
+  app         Service Mesh Apps Management
+  completion  generate the autocompletion script for the specified shell
+  exp         Experimental commands for mesheryctl
+  help        Help about any command
+  mesh        Service Mesh Lifecycle Management
+  pattern     Service Mesh Patterns Management
+  perf        Performance Management
+  system      Meshery Lifecycle Management
+  version     Version of mesheryctl
+
+Flags:
+      --config string   path to config file (default "/Users/navendu/.meshery/config.yaml")
+  -h, --help            help for mesheryctl
+  -v, --verbose         verbose output
+
+Use "mesheryctl [command] --help" for more information about a command.
+```
+
+## Run a performance test
+
+See [this guide](https://docs.meshery.io/reference/mesheryctl#service-mesh-performance-management) for reference to mesheryctl commands.
+
+The command below runs a performance benchmark test with Nighthawk with the test configuration provided through flags.
+
+```
+mesheryctl perf apply --profile istio-soak-test --concurrent-requests 1 --duration 15s --load-generator nighthawk --mesh istio --url http://localhost:2323
+```
+
+You can also run performance tests with SMP compatible test configuration files like the one shown below.
+
+```yaml
+smp_version: v0.0.1
+id: d3ac6bf7-e35e-40c0-8669-5e13c9657286
+name: istio-soak-test
+labels: {}
+clients:
+- internal: false
+  load_generator: nighthawk
+  protocol: 1
+  connections: 2
+  rps: 10
+  headers: {}
+  cookies: {}
+  body: ""
+  content_type: ""
+  endpoint_urls:
+  - http://localhost:2323
+duration: "15s"
+```
+
+You can then use `mesheryctl` to run the test using this configuration file as shown below.
+
+```
+mesheryctl perf apply -f perf-test.yaml
+```
+
+Check the [Meshery usage guides](https://docs.meshery.io/guides) for more information on running performance benchmarks.

+GetNighthawk provides a [Go package](https://github.com/layer5io/getnighthawk/tree/master/pkg/client) which the users can leverage to use Nighthawk.
+
+GetNighthawk also provides a gRPC Go stub which can be used to interact with a running service.
+
+[Client and Server binaries](https://github.com/layer5io/getnighthawk/tree/master/apinighthawk/bin) of Nighthawk are also built and ready to be used.
+
+GetNighthawk also provides a Docker image that can be pulled from here.
