Browse source 
* clarify link

* Add section headers

* console blocks

* grpc example json was not valid

* multi-tls update text

The preceding point 1 related to 4f2cb51ef8/ingress/controllers/nginx/examples/ingress.yaml
and the deployments referenced in 4f2cb51ef8/ingress/controllers/nginx/examples/README.md

They are not relevant to the current instructions.

* add whitespace around parens

* grammar

setup would be a proper noun, but it is not the intended concept, which is a state

* grammar

* is-only
* via

* Use bullets for choices

* ingress-controller

nginx is a distinct brand.

generally this repo talks about ingress-controller, although it is quite inconsistent about how...

* drop stray paren

* OAuth is a brand and needs an article here

also GitHub is a brand

* Indent text under numbered lists

* use e.g.

* Document that customer header config maps changes do not trigger updates

This should be removed if
https://github.com/kubernetes/ingress-nginx/issues/5238
is fixed.

* article

* period

* infinitive verb + period

* clarify that the gRPC server is responsible for listening for TCP traffic and not some other part of the backend application

* avoid using ; and reword

* whitespace

* brand: gRPC

* only-does is the right form

`for` adds nothing here

* spelling: GitHub

* punctuation

`;` is generally not the right punctuation...

* drop stray `to`

* sentence

* backticks

* fix link

* Improve readability of compare/vs

* Renumber list

* punctuation

* Favor Ingress-NGINX and Ingress NGINX

* Simplify custom header restart text

* Undo typo damage

# Custom Headers
## Caveats
Changes to the custom header config maps do not force a reload of the ingress-nginx-controllers.
### Workaround
To work around this limitation, perform a rolling restart of the deployment.
## Example
This example demonstrates configuration of the nginx ingress controller via
a ConfigMap to pass a custom list of headers to the upstream
server.

## Test
Check the contents of the ConfigMaps are present in the nginx.conf file using:
`kubectl exec ingress-nginx-controller-873061567-4n3k2 -n ingress-nginx -- cat /etc/nginx/nginx.conf`
