+## Custom Rules
+In additional the default set of rules, custom rules can provided as node modules; the mechanism is similar that used by tools such as eslint.
+
+An example is provided in [`custom_rules`](./custom_rules), and will be used in the examples below. Notes on writing rules are also in the [README.md](./custom_rules/README.md)
+
+### Configuring
+
+In the `.tektonrc.yaml` file add an object with names of the rules and node module that provides it.
+To load rules exported by the module `custom_rules`, and named under `my_rules` add the `custom` field to the yaml file.
+
+```yaml
+---
+rules:
+  ....
+external:tasks:
+  ...
+custom: 
+ my_rules: custom_rules 
+ # For debug and test, refer directly to the js file
+ # my_rules: ../customer_rules/my_rules.js
+```
+
+### Reporting
+
+A module may report more than one rule. There is one rule in the example, and this flags up any task that starts with the work 'Task' (not meant to be serious rule, but an example!)
+
+Running on the `example-task.yaml` file with the example configured adds a 4th report
+
+```
+./example-task.yaml
+  10:14  warning  Invalid image: 'busybox'. Specify the image tag instead of using ':latest'          no-latest-image
+   9:31  error    Undefined param 'contextDir' at .spec.steps[0].command[2] in 'Task-without-params'  no-undefined-param
+  11:19  error    Undefined param 'contextDir' at .spec.steps[0].workingDir in 'Task-without-params'  no-undefined-param
+   1:1   error    Tasks should not start with word 'Task'                                             my_rules#no-tasks-called-task
+
+✖ 4 problems (3 errors, 1 warning)
+```
+
+Within the representation of the rule name here `my_rules#no-tasks-called-task`; if you want to turn off this rule, then you can adjust the list of rules in the `.tektonrc.yaml` as for another rule
+
+```
+rules:
+  ...
+  my_rules#no-tasks-called-task: off
+```

+# Tekton Lint custom rules
+
+- Create a regular node module
+- Default export from this of an object
+```js
+module.exports = {
+    rules: [
+        {
+            name: 'no-tasks-called-task',
+            reportDefault: 'error',
+            ruleFn: forbidTasksWithTaskInTheName
+        }
+    ]
+}
+```
+    - Must contain a field called `rules` that is a array of objects
+    - Each 'rule' object, must hava name (kebab case preferred)
+    - Default report type (off/error/warning)
+    - Reference to the rules function
+
+- Rules are implemented in a function
+
+```js
+// Example rule to check a name of a task, note this isn't meant
+// to be a serious rule - rather as an example
+const forbidTasksWithTaskInTheName = (docs, tekton, report) => {
+
+    // try to always code defensively
+    if (tekton.tasks) {
+        for (const t of Object.values(tekton.tasks)) {
+            if (t.metadata.name.startsWith("Task")) {
+                report("Tasks should not start with word 'Task'", t)
+            }
+        }
+    }
+};
+```
+
+    - `docs` are the full yaml docs
+    - `tekton` is the object with the parsed elements of the yaml files
+    - `report` is a fn to report rule breaks
+
+
+## Development Notes:
+
+- As well as the yaml files from the project being tested, the rule will also see the cached elements
+- try and code as defensively as possible, eg a set of files might not have Tasks
