+# CONTRIBUTE
+We welcome code contributions from the community.
+Please read and follow the guidelines below.
+
+## Communication
+* Before starting work on a major feature, please reach out to us via [GitHub](https://github.com/up9inc/mizu), [Slack](https://join.slack.com/share/zt-u6bbs3pg-X1zhQOXOH0yEoqILgH~csw), [email](mailto:mizu@up9.com), etc. We will make sure no one else is already working on it. A _major feature_ is defined as any change that is > 100 LOC altered (not including tests), or changes any user-facing behavior
+* Small patches and bug fixes don't need prior communication.
+
+## Contribution requirements
+* Code style - most of the code is written in Go, please follow [these guidelines](https://golang.org/doc/effective_go)
+* Go-tools compatible (`go get`, `go test`, etc)
+* Unit-test coverage can’t go down ..
+* Code must be usefully commented. Not only for developers on the project, but also for external users of these packages
+* When reviewing PRs, you are encouraged to use Golang's [code review comments page](https://github.com/golang/go/wiki/CodeReviewComments)

-In case no config file found, defaults will be used. <br />
-In case of partial configuration defined, all other fields will be used with defaults. <br />

 To get the default config params run `mizu config` <br />
 To generate a new config file with default values use `mizu config -r`
 
-Mizu has several undocumented flags which can be set by using --set flag (e.g., `mizu tap --set dump-logs=true`)
-* **mizu-resources-namespace**: Type - String, See [Namespace-Restricted Mode](#namespace-restricted-mode)
-* **telemetry**: Type - Boolean, Reports telemetry
-* **dump-logs**: Type - Boolean, At the end of the execution it creates a zip file with logs (in .mizu folder)
-* **kube-config-path**: Type - String, Setting the path to kube config (which isn't in standard path)
+### Telemetry
+
+By default, mizu reports usage telemetry. It can be disabled by adding a line of `telemetry: false` in the `${HOME}/.mizu/config.yaml` file
+
 
 ## Advanced Usage
 
 ### Namespace-Restricted Mode
 
-Some users have permission to only manage resources in one particular namespace assigned to them.

 to the namespace set by `mizu-resources-namespace`. The user must set the tapped namespace to the same namespace by

+This feature allows you to define set of simple rules, and test the API against them.
+Such validation may test response for specific JSON fields, headers, etc.

+# API rules validation
+
+This feature allows you to define set of simple rules, and test the API against them.
+Such validation may test response for specific JSON fields, headers, etc.
+
+## Examples
+
+
+Example 1: HTTP request (REST API call) that didn’t pass validation is highlighted in red
+
+![Simple UI](../assets/validation-example1.png)
+
+- - -
+
+
+Example 2: Details pane shows the validation rule details and whether it passed or failed
+
+![Simple UI](../assets/validation-example2.png)
+
+
+## How to use
+To use this feature - create simple rules file (see details below) and pass this file as parameter to `mizu tap` command. For example, if rules are stored in file named `rules.yaml` — run the following command:
+
+
+```shell
+mizu tap --test-rules rules.yaml PODNAME
+```
+
+
+
+## Rules file structure
+
+The structure of the test-rules-file is:
+
+* `name`: string, name of the rule
+* `type`: string, type of the rule, must be `json` or `header` or `latency`
+* `key`: string, [jsonpath](https://code.google.com/archive/p/jsonpath/wikis/Javascript.wiki) used only in `json` or `header` type
+* `value`: string, [regex](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) used only in `json` or `header` type
+* `service`: string, [regex](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) service name to filter
+* `path`: string, [regex](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) URL path to filter
+* `latency`: integer, time in ms of the expected latency.
+
+
+### For example:
+
+```yaml
+rules:
+- name: holy-in-name-property
+  type: json
+  key: "$.name"
+  value: "Holy"
+  service: "catalogue.*"
+  path: "catalogue.*"
+- name: content-length-header
+  type: header
+  key: "Content-Le.*"
+  value: "(\\d+(?:\\.\\d+)?)"
+- name: latency-test
+  type: latency
+  latency: 1
+  service: "carts.*"
+```

+### Explanation:
+
+* First rule `holy-in-name-property`:
+
+  > This rule will be applied to all request made to `catalogue.*` services with `catalogue.*` on the URL path with a json response containing a `$.name` field. If the value of `$.name` is `Holy` than is marked as success, marked as failure otherwise.
+
+* Second rule `content-length-header`:
+
+  > This rule will be applied to all request that has `Content-Le.*` on header. If the value of `Content-Le.*` is `(\\d+(?:\\.\\d+)?)` (number), will be marked as success, marked as failure otherwise.
+
+* Third rule `latency-test`:
+
+  > This rule will be applied to all request made to `carts.*` services. If the latency of the response is greater than `1` will be marked as failure, marked as success otherwise.

+Reads a frame from an input stream and returns an interface that can be cast into
+one of the following:
+
+   MethodFrame
+   PropertiesFrame
+   BodyFrame
+   HeartbeatFrame
+
+2.3.5  frame Details
+
+All frames consist of a header (7 octets), a payload of arbitrary size, and a
+'frame-end' octet that detects malformed frames:
+
+  0      1         3             7                  size+7 size+8

+  +------+---------+-------------+  +------------+  +-----------+
+   octet   short         long         size octets       octet
+
+To read a frame, we:
+  1. Read the header and check the frame type and channel.
+	2. Depending on the frame type, we read the payload and process it.
+  3. Read the frame end octet.
+
+In realistic implementations where performance is a concern, we would use
+“read-ahead buffering” or
+
+“gathering reads” to avoid doing three separate system calls to read a frame.
