 For changes to its dependencies, the `dep` dependency management tool is required.
 
 ### Method 1: Using `Docker` and `Makefile`
 
 Run make with the `binary` target.

+```bash
+make binary

+
 This will create binaries for the Linux platform in the `dist` folder.
 
 In case when you run build on CI, you may probably want to run docker in non-interactive mode. To achieve that define `DOCKER_NON_INTERACTIVE=true` environment variable.

+## What does the "field not found" error mean?
+
+```shell
+error: field not found, node: -badField-

+
+The "field not found" error occurs, when an unknown property is encountered in the dynamic or static configuration.
+
+One easy way to check whether a configuration file is well-formed, is to validate it with:
+
+- [JSON Schema of the static configuration](https://json.schemastore.org/traefik-v2.json)
+- [JSON Schema of the dynamic configuration](https://json.schemastore.org/traefik-v2-file-provider.json)
+
+## Why are some resources (routers, middlewares, services...) not created/applied?
+
+As a common tip, if a resource is dropped/not created by Traefik after the dynamic configuration was evaluated,
+one should look for an error in the logs.
+
+If found, the error obviously confirms that something went wrong while creating the resource,
+and the message should help in figuring out the mistake(s) in the configuration, and how to fix it.

+
+```yaml
+traefik.consulcatalog.canary=true
+```
+
+When ConsulCatalog, in the context of a Nomad orchestrator,
+is a provider (of service registration) for Traefik,
+one might have the need to distinguish within Traefik between a [Canary](https://learn.hashicorp.com/tutorials/nomad/job-blue-green-and-canary-deployments#deploy-with-canaries) instance of a service, or a production one.
+For example if one does not want them to be part of the same load-balancer.
+
+Therefore, this option, which is meant to be provided as one of the values of the `canary_tags` field in the Nomad [service stanza](https://www.nomadproject.io/docs/job-specification/service#canary_tags),
+allows Traefik to identify that the associated instance is a canary one.
+
 #### Port Lookup
 
 Traefik is capable of detecting the port to use, by following the default consul Catalog flow.
