 The Prometheus monitoring mixin for Jaeger provides a starting point for people wanting to monitor Jaeger using Prometheus, Alertmanager, and Grafana. To use it, you'll need [`jsonnet`](https://github.com/google/go-jsonnet) and [`jb` (jsonnet-bundler)](https://github.com/jsonnet-bundler/jsonnet-bundler). They can be installed using `go get`, as follows:
 
 ```console
-$ mkdir -p ~/bin && curl -sL https://github.com/google/go-jsonnet/releases/download/v0.17.0/go-jsonnet_0.17.0_Linux_x86_64.tar.gz | tar -C ~/bin/ -xzf -
-$ curl -sLo ~/bin/jb https://github.com/jsonnet-bundler/jsonnet-bundler/releases/download/v0.4.0/jb-linux-amd64
-$ chmod +x ~/bin/jb

+chmod +x ~/bin/jb
 ```
 
 Your monitoring mixin can then be initialized as follows:
 
 ```console
-$ jb init
-$ jb install \
+jb init
+jb install \
   github.com/jaegertracing/jaeger/monitoring/jaeger-mixin@master \

 The manifest files can be generated via the `jsonnet` command below. Once the command finishes, the file `manifests/dashboards-jaeger.json` should be available and can be loaded directly into Grafana.

 The manifest files can be generated via `jsonnet` and passed directly to `kubectl`:
 
 ```console
-$ jsonnet -J vendor -cm manifests/ monitoring-setup.jsonnet
-$ kubectl apply -f manifests/
+jsonnet -J vendor -cm manifests/ monitoring-setup.jsonnet

 The resulting manifests will include everything that is needed to have a Prometheus, Alertmanager, and Grafana instances. Whenever a new alert rule is needed, or a new dashboard has to be defined, change your `monitoring-setup.jsonnet`, re-generate and re-apply the manifests.
 
 Make sure your Prometheus setup is properly scraping the Jaeger components, either by creating a `ServiceMonitor` (and the backing `Service` objects), or via `PodMonitor` resources, like:
 
 ```console
-$ kubectl apply -f - <<EOF
+kubectl apply -f - <<EOF
