+# Contributing
+
+So you want to help? That's great!
+
+![Image of happy people jumping with excitement](https://media.giphy.com/media/BlVnrxJgTGsUw/giphy.gif)
+
+Here are a few things to know to get you started on the right path.
+
+## Committing code
+
+We make all changes via pull requests. As we have many pull requests from developers new to mermaid, the current approach is to have *knsv, Knut Sveidqvist* as a main reviewer of changes and merging pull requests. More precisely like this:
+
+* Large changes reviewed by knsv or other developer asked to review by knsv
+* Smaller low-risk changes like dependecies, documentation etc can be merged by active collaborators
+* documentation (updates to the docs folder is also allowed via direct commits)
+
+To commit code, create a branch, let it start with the type like feature or bug followed by the issue number for reference and some describing text.
+
+One example:
+
+`feature/945_state_diagrams`
+
+Another:
+
+`bug/123_nasty_bug_branch`
+
+## Committing documentation
+
+Less strict here, it is ok to commit directly in the develop branch if you are a collaborator.
+
+## Branching
+
+Going forward we will use a git flow inspired approach to branching. So development is done in develop, to do the development in the develop.
+
+Once development is done we branch a release branch from develop for testing.
+
+Once the release happens we merge the release branch to master and kill the release branch.
+
+This means... **branch off your pull request from develop**
+
+## Content of a pull request
+
+A new feature has been born. Great! But without the steps below it might just ... fade away ...
+
+### **Add unit tests for the parsing part**
+
+This is important so that, if someone else does a change to the grammar that does not know about this great feature, gets notified early on when that change breaks the parser. Another important aspect is that without proper parsing tests refactoring is pretty much impossible.
+
+### **Add e2e tests**
+
+This tests the rendering and visual apearance of the diagram. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
+
+To start working with the e2e tests, run `yarn dev` to start the dev server, after that start cypress by running `cypress open` in the mermaid folder. (Make sure you have path to cypress in order, the binary is located in node_modules/.bin).
+
+The rendering tests are very straightforward to create. There is a function imgSnapshotTest. This function takes a diagram in text form, the mermaid options and renders that diagram in cypress.
+
+When running in ci it will take a snapshot of the rendered diagram and compare it with the snapshot from last build and flag for review it if it differs.
+
+This is what a rendering test looks like:
+```
+  it('should render forks and joins', () => {
+    imgSnapshotTest(
+      `
+    stateDiagram
+    state fork_state <<fork>>
+      [*] --> fork_state
+      fork_state --> State2
+      fork_state --> State3
+
+      state join_state <<join>>
+      State2 --> join_state
+      State3 --> join_state
+      join_state --> State4
+      State4 --> [*]
+    `,
+      { logLevel: 0 }
+    );
+    cy.get('svg');
+  });
+  ```
+
+
+### **Add documentation for it**
+
+Finally, if it is not in the documentation, no one will know about it and then **no one will use it**. Wouldn't that be sad? With all the effort that was put into the feature?
+
+The docs are located in the docs folder and are ofc written in markdown. Just pick the right section and start typing. If you want to add to the structure as in adding a new section and new file you do that via the _navbar.md.
+
+The changes in master is reflected in http://mermaid-js.github.io/mermaid/ once released the updates are commited to https://mermaid-js.github.io/#/
+
+## Last words
+
+Don't get daunted if it is hard in the beginning. We have a great community with only encouraging words. So if you get stuck, ask for help and hints in the slack forum. If you want to show off something good, show it off there.

+## New diagram
+
+This version comes with a new diagram type, user journey diagrams.
+
+## New diagrams in 8.4
+
+With version 8.4 class diagrams have got some new features, bug fixes and documentation. Another new feature in 8.4 is the new diagram type, state diagrams.
+
+![Image show the two new diagram types](./docs/img/new-diagrams.png)
 
 ## Special note regarding version 8.2
 
 In version 8.2 a security improvement was introduced. A securityLevel configuration was introduced which sets the level of trust to be used on the parsed diagrams.
 
-* **`strict`**: (default) tags in text are encoded, click functionality is disabled
-* `loose`: tags in text are allowed, click functionality is enabledClosed issues:
+- **true**: (default) tags in text are encoded, click functionality is disabled
+- false: tags in text are allowed, click functionality is enabled
+
+Closed issues:
 
 ⚠️ **Note** : This changes the default behaviour of mermaid so that after upgrade to 8.2, if the securityLevel is not configured, tags in flowcharts are encoded as tags and clicking is prohibited.
 
-If your application is taking responsibility for the diagram source security you can set the securityLevel accordingly. By doing this clicks and tags are again allowed.
+If your application is taking resposibility for the diagram source security you can set the securityLevel accordingly. By doing this clicks and tags are again allowed.
 
 ```javascript
-    mermaidAPI.initialize({
-        securityLevel: 'loose'
-    });
+mermaidAPI.initialize({
+    securityLevel: 'loose'
+});

+For more information and help in getting started, please view our [documentation](http://mermaid-js.github.io/mermaid/) and start simplifying yours. Play with our [live editor](https://mermaidjs.github.io/mermaid-live-editor/) or jump straight to the [installation and usage](http://mermaid-js.github.io/mermaid/#/usage).

-
-Generation of diagrams and flowcharts from text in a similar manner as markdown.
-
-Ever wanted to simplify documentation and avoid heavy tools like Visio when explaining your code?
-
-This is why mermaid was born, a simple markdown-like script language for generating charts from text via javascript.
-
-**Mermaid was nominated and won the JS Open Source Awards (2019) in the category _The most exciting use of technology_!!! Thanks to all involved, people committing pull requests, people answering questions and special thanks to Tyler Long who is helping me maintain the project.**

-# Request for assistance
-
-Things are piling up and I have hard time keeping up. To remedy this
-it would be great if we could form a core team of developers to cooperate
-with the future development mermaid.
-
-As part of this team you would get write access to the repository and would
-represent the project when answering questions and issues.
-
-Together we could continue the work with things like:
-* adding more types of diagrams like mindmaps, ert diagrams etc
-* improving existing diagrams
-
-Don't hesitate to contact me if you want to get involved.
-
-
-# For contributors
-
-## Setup
-
-    yarn install
-
-
-## Build
-
-    yarn build:watch
-
-
-## Lint
-
-    yarn lint
-
-We use [JavaScript Standard Style](https://github.com/feross/standard).
-We recommend you installing [editor plugins](https://github.com/feross/standard#are-there-text-editor-plugins) so you can get real time lint result.
-
-
-## Test
-
-    yarn test
-
-Manual test in browser:
-
-    open dist/index.html
-
-
-## Release
-
-For those who have the permission to do so:
-
-Update version number in `package.json`.
-
-    npm publish
-
-Command above generates files into the `dist` folder and publishes them to npmjs.org.

+# Class diagrams
+
+> "In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects."
+ Wikipedia
+
+The class diagram is the main building block of object-oriented modeling. It is used for general conceptual modeling of the structure of the application, and for detailed modeling translating the models into programming code. Class diagrams can also be used for data modeling. The classes in a class diagram represent both the main elements, interactions in the application, and the classes to be programmed.
+
+Mermaid can render class diagrams.
+
+```
+ classDiagram
+      Animal <|-- Duck
+      Animal <|-- Fish
+      Animal <|-- Zebra
+      Animal : +int age
+      Animal : +String gender
+      Animal: +isMammal()
+      Animal: +mate()
+      class Duck{
+          +String beakColor
+          +swim()
+          +quack()
+      }
+      class Fish{
+          -int sizeInFeet
+          -canEat()
+      }
+      class Zebra{
+          +bool is_wild
+          +run()
+      }
+
+```
+```mermaid

+      }
+
+```
+
+## Syntax
+
+### Class
+
+UML provides mechanisms to represent class members, such as attributes and methods, and additional information about them.
+A single instance of a class in the diagram contains three compartments:
+ - The top compartment contains the name of the class. It is printed in bold and centered, and the first letter is capitalized. It may also contain optional annotation text describing the nature of the class.
+ - The middle compartment contains the attributes of the class. They are left-aligned and the first letter is lowercase.
+ - The bottom compartment contains the operations the class can execute. They are also left-aligned and the first letter is lowercase.
+
+```
+classDiagram
+    class BankAccount
+    BankAccount : +String owner
+    BankAccount : +Bigdecimal balance
+    BankAccount : +deposit(amount)
+    BankAccount : +withdrawl(amount)
+```
+```mermaid
+classDiagram
+    class BankAccount
+    BankAccount : +String owner
+    BankAccount : +BigDecimal balance
+    BankAccount : +deposit(amount)
+    BankAccount : +withdrawl(amount)
+```
+## Define a class
+
+There are two ways to define a class:
+- Explicitly defining a class using keyword **class** like `class Animal`. This defines the Animal class
+- Define two classes via a **relationship** between them `Vehicle <|-- Car`. This defines two classes Vehicle and Car along with their relationship.
+
+```
+classDiagram
+    class Animal
+    Vehicle <|-- Car
+```
+```mermaid
+classDiagram
+    class Animal
+    Vehicle <|-- Car
+```
+
+Naming convention: a class name should be composed of alphanumeric (unicode allowed) and underscore characters.
+
+## Defining Members of a class
+
+UML provides mechanisms to represent class members, such as attributes and methods, and additional information about them.
+
+Mermaid distinguishes between attributes and functions/methods based on if the **parenthesis** `()` are present or not. The ones with `()` are treated as functions/methods, and others as attributes.
+
+
+There are two ways to define the members of a class, and regardless of whichever syntax is used to define the members, the output will still be same. The two different ways are :
+- Associate a member of a class using **:** (colon) followed by member name, useful to define one member at a time. For example:
+
+ ```
+  class BankAccount
+  BankAccount : +String owner
+  BankAccount : +BigDecimal balance
+  BankAccount : +deposit(amount)
+  BankAccount : +withdrawal(amount)
+  ```
+
+  ```  mermaid
+    classDiagram
+    class BankAccount
+    BankAccount : +String owner
+    BankAccount : +BigDecimal balance
+    BankAccount : +deposit(amount)
+    BankAccount : +withdrawl(amount)
+  ```
+
+- Associate members of a class using **{}** brackets, where members are grouped within curly brackets. Suitable for defining multiple members at once. For example:
+```
+class BankAccount{
+    +String owner
+    +BigDecimal balance
+    +deposit(amount) bool
+    +withdrawl(amount)
+}
+```
+```mermaid
+  classDiagram
+    class BankAccount{
+        +String owner
+        +BigDecimal balance
+        +deposit(amount) bool
+        +withdrawl(amount) int
+}
+```
+
+#### Return Type
+Optionally you can end the method/function definition with the data type that will be returned (note: there must be a space between the final `)` of the method definition and return type
+example:
+```
+class BankAccount{
+    +String owner
+    +BigDecimal balance
+    +deposit(amount) bool
+    +withdrawl(amount) int
+}
+```
+```mermaid
+    classDiagram
+    class BankAccount{
+        +String owner
+        +BigDecimal balance
+        +deposit(amount) bool
+        +withdrawl(amount) int
+}
+```
+
+#### Generic Types
+Members can be defined using generic types, such as `List<int>`, for fields, parameters and return types by enclosing the type within `~` (**tilde**). Note: **nested** type declarations (such as `List<List<int>>`) are not currently supported
+
+This can be done as part of either class definition method:
+
+```
+classDiagram
+class Square~Shape~{
+    int id
+    List~int~ position
+    setPoints(List~int~ points)
+    getPoints() List~int~
+}
+
+Square : -List~string~ messages
+Square : +setMessages(List~string~ messages)
+Square : +getMessages() List~string~
+```
+
+```mermaid
+classDiagram
+class Square~Shape~{
+    int id
+    List~int~ position
+    setPoints(List~int~ points)
+    getPoints() List~int~
+}
+
+Square : -List~string~ messages
+Square : +setMessages(List~string~ messages)
+Square : +getMessages() List~string~
+```
+
+#### Return Type
+Optionally you can end the method/function definition with the data type that will be returned
+
+#### Visibility
+To specify the visibility of a class member (i.e. any attribute or method), these notations may be placed before the member's name, but it is optional:
+
+- `+`	Public
+- `-`	Private
+- `#`	Protected
+- `~`	Package/Internal
+
+>_note_ you can also include additional _classifers_ to a method definition by adding the following notations to the end of the method, i.e.: after the `()`:
+> - `*` Abstract e.g.: `someAbstractMethod()*`
+> - `$` Static e.g.: `someStaticMethod()$`
+
+
+## Defining Relationship
+A relationship is a general term covering the specific types of logical connections found on class and object diagrams.
+```
+[classA][Arrow][ClassB]:LabelText
+```
+
+There are different types of relations defined for classes under UML which are currently supported:
+
+Type | Description
+---   | ---
+<\|-- | Inheritance
+*--   | Composition
+o--   | Aggregation
+-->   | Association
+--    | Link (Solid)
+..>   | Dependency
+..\|> | Realization
+..    | Link (Dashed)
+
+```
+classDiagram
+classA <|-- classB
+classC *-- classD
+classE o-- classF
+classG <-- classH
+classI -- classJ
+classK <.. classL
+classM <|.. classN
+classO .. classP
+
+```
+
+```mermaid
+classDiagram
+classA <|-- classB
+classC *-- classD
+classE o-- classF
+classG <-- classH
+classI -- classJ
+classK <.. classL
+classM <|.. classN
+classO .. classP
+
+```
+We can use the labels to describe nature of relation between two classes. Also, arrowheads can be used in opposite directions as well :
+```
+classDiagram
+classA --|> classB : Inheritance
+classC --* classD : Composition
+classE --o classF : Aggregation
+classG --> classH : Association
+classI -- classJ : Link(Solid)
+classK ..> classL : Dependency
+classM ..|> classN : Realization
+classO .. classP : Link(Dashed)
+
+```
+
+```mermaid
+classDiagram
+classA --|> classB : Inheritance
+classC --* classD : Composition
+classE --o classF : Aggregation
+classG --> classH : Association
+classI -- classJ : Link(Solid)
+classK ..> classL : Dependency
+classM ..|> classN : Realization
+classO .. classP : Link(Dashed)
+
+
+```
+## Labels on Relations
+
+It is possible to add a label text to a relation:
+```
+[classA][Arrow][ClassB]:LabelText
+```
+```
+classDiagram
+classA <|-- classB : implements
+classC *-- classD : composition
+classE o-- classF : association
+```
+```mermaid
+classDiagram
+classA <|-- classB : implements
+classE o-- classF : association
+
+```
+## Cardinality / Multiplicity on relations
+Multiplicity or cardinality in class diagrams indicates the number of instances of one class linked to one instance of the other class. For example, one company will have one or more employees, but each employee works for just one company.
+
+Multiplicity notations are placed near the ends of an association.
+
+The different cardinality options are :
+- `0..1`        Zero or one
+- `1`           Only 1
+- `0..1`	    Zero or One
+- `1..*`        One or more
+- `*`           Many
+- `n`           n {where n>1}
+- `0..n`        zero to n {where n>1}
+- `1..n`        one to n {where n>1}
+
+Cardinality can be easily defined by placing cardinality text within qoutes `"` before(optional) and after(optional) a given arrow.
+```
+[classA] "cardinality1" [Arrow] "cardinality2" [ClassB]:LabelText
+```
+```
+classDiagram
+    Customer "1" --> "*" Ticket
+    Student "1" --> "1..*" Course
+    Galaxy --> "many" Star : Contains
+```
+```mermaid
+classDiagram
+    Customer "1" --> "*" Ticket
+    Student "1" --> "1..*" Course
+    Galaxy --> "many" Star : Contains
+```
+## Annotations on classes
+
+It is possible to annotate classes with a specific marker text which is like meta-data for the class, giving a clear indication about its nature. Some common annotations examples could be:
+- `<<Interface>>`   To represent an Interface class
+- `<<abstract>>`      To represent an abstract class
+- `<<Service>>`     To represent a service class
+- `<<enumeration>>` To represent an enum
+
+Annotations are defined within the opening `<<` and closing `>>`. There are two ways to add an annotation to a class and regardless of the syntax used output will be same. The two ways are :
+- In a ***separate line*** after a class is defined. For example:
+```
+classDiagram
+class Shape
+<<interface>> Shape
+```
+
+```mermaid
+classDiagram
+class Shape
+<<interface>> Shape
+Shape : noOfVertices
+Shape : draw()
+```
+- In a ***nested structure*** along with class definition. For example:
+
+```
+classDiagram
+class Shape{
+    <<interface>>
+    noOfVertices
+    draw()
+}
+class Color{
+    <<enumeration>>
+    RED
+    BLUE
+    GREEN
+    WHITE
+    BLACK
+}
+
+```
+
+```mermaid
+classDiagram
+class Shape{
+    <<interface>>
+    noOfVertices
+    draw()
+}
+class Color{
+    <<enumeration>>
+    RED
+    BLUE
+    GREEN
+    WHITE
+    BLACK
+}
+```
+
+## Comments
+
+Comments can be entered within a class diagram, which will be ignored by the parser.  Comments need to be on their own line, and must be prefaced with `%%` (double percent signs). Any text after the start of the comment to the next newline will be treated as a comment, including any class diagram syntax
+
+```
+classDiagram
+%% This whole line is a comment classDiagram class Shape <<interface>>
+class Shape{
+    <<interface>>
+    noOfVertices
+    draw()
+}
+
+```
+
+## Interaction
+
+It is possible to bind a click event to a node, the click can lead to either a javascript callback or to a link which will be opened in a new browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.
+
+You would define these actions on a separate line after all classes have been declared.
+
+```
+action className "reference" "tooltip"
+```
+
+* _action_ is either `link` or `callback`, depending on which type of interaction you want to have called
+* _className_ is the id of the node that the action will be associated with
+* _reference_ is either the url link, or the function name for callback. (note: callback function will be called with the nodeId as parameter).
+* (_optional_) tooltip is a string to be displayed when hovering over element (note: The styles of the tooltip are set by the class .mermaidTooltip.)
+
+### Examples:
+
+*URL Link:*
+
+```
+classDiagram

+## Styling
+
+Styling of the class diagram is done by defining a number of css classes.  During rendering these classes are extracted from the file located at src/themes/class.scss

+# Entity Relationship Diagrams
+
+> An entity–relationship model (or ER model) describes interrelated things of interest in a specific domain of knowledge. A basic ER model is composed of entity types (which classify the things of interest) and specifies relationships that can exist between entities (instances of those entity types). Wikipedia.
+
+Note that practitioners of ER modelling almost always refer to *entity types* simply as *entities*.  For example the CUSTOMER entity type would be referred to simply as the CUSTOMER entity.  This is so common it would be inadvisable to do anything else, but technically an entity is an abstract *instance* of an entity type, and this is what an ER diagram shows - abstract instances, and the relationships between them.  This is why entities are always named using singular nouns.
+
+Mermaid can render ER diagrams
+```
+erDiagram
+    CUSTOMER ||--o{ ORDER : places
+    ORDER ||--|{ LINE-ITEM : contains
+    CUSTOMER }|..|{ DELIVERY-ADDRESS : uses 
+```
+```mermaid
+erDiagram
+    CUSTOMER ||--o{ ORDER : places
+    ORDER ||--|{ LINE-ITEM : contains
+    CUSTOMER }|..|{ DELIVERY-ADDRESS : uses 
+```
+
+Entity names are often capitalised, although there is no accepted standard on this, and it is not required in Mermaid.
+
+Relationships between entities are represented by lines with end markers representing cardinality.  Mermaid uses the most popular crow's foot notation. The crow's foot intuitively conveys the possibility of many instances of the entity that it connects to.
+
+## Status
+
+ER diagrams are a new feature in Mermaid and are **experimental**.  There are likely to be a few bugs and constraints, and enhancements will be made in due course.  Currently you can only define entities and relationships, but not attributes.
+
+## Syntax
+
+### Entities and Relationships
+
+Mermaid syntax for ER diagrams is compatible with PlantUML, with an extension to label the relationship.  Each statement consists of the following parts, all of which are mandatory:
+```
+    <first-entity> <relationship> <second-entity> : <relationship-label>
+```
+Where:
+
+- `first-entity` is the name of an entity.  Names must begin with an alphabetic character and may also contain digits and hyphens
+- `relationship` describes the way that both entities inter-relate.  See below.
+- `second-entity` is the name of the other entity
+- `relationship-label` describes the relationship from the perspective of the first entity.
+
+For example:
+
+```
+    PROPERTY ||--|{ ROOM : contains
+```
+
+This statement can be read as *a property contains one or more rooms, and a room is part of one and only one property*. You can see that the label here is from the first entity's perspective: a property contains a room, but a room does not contain a property.  When considered from the perspective of the second entity, the equivalent label is usually very easy to infer. (Some ER diagrams label relationships from both perspectives, but this is not supported here, and is usually superfluous).
+
+### Relationship Syntax
+
+The `relationship` part of each statement can be broken down into three sub-components: 
+
+- the cardinality of the first entity with respect to the second, 
+- whether the relationship confers identity on a 'child' entity
+- the cardinality of the second entity with respect to the first
+
+Cardinality is a property that describes how many elements of another entity can be related to the entity in question.  In the above example a `PROPERTY` can have one or more `ROOM` instances associated to it, whereas a `ROOM` can only be associated with one `PROPERTY`.  In each cardinality marker there are two characters.  The outermost character represents a maximum value, and the innermost character represents a minimum value.  The table below summarises possible cardinalities.
+
+| Value (left) | Value (right) | Meaning                                                |
+|:------------:|:-------------:|--------------------------------------------------------|
+|     `\|o`    |       `o\|`   | Zero or one                                            |
+|     `\|\|`   |       `\|\|`  | Exactly one                                            |
+|     `}o`     |       `o{`    | Zero or more (no upper limit)                          |
+|     `}\|`    |       `\|{`   | One or more (no upper limit)                           |
+
+### Identification
+
+Relationships may be classified as either *identifying* or *non-identifying* and these are rendered with either solid or dashed lines respectively. This is relevant when one of the entities in question can not have independent existence without the other.  For example a firm that insures people to drive cars might need to store data on `NAMED-DRIVER`s. In modelling this we might start out by observing that a `CAR` can be driven by many `PERSON` instances, and a `PERSON` can drive many `CAR`s - both entities can exist without the other, so this is a non-identifying relationship that we might specify in Mermaid as: `PERSON }|..|{ CAR : "driver"`.  Note the two dots in the middle of the relationship that will result in a dashed line being drawn between the two entities.  But when this many-to-many relationship is resolved into two one-to-many relationships, we observe that a `NAMED-DRIVER` cannot exist without both a `PERSON` and a `CAR` - the relationships become identifying and would be specified using hyphens, which translate to a solid line: 
+
+```
+    CAR ||--o{ NAMED-DRIVER : allows
+    PERSON ||--o{ NAMED-DRIVER : is
+```
+### Other Things
+
+- If you want the relationship label to be more than one word, you must use double quotes around the phrase
+- If you don't want a label at all on a relationship, you must use an empty double-quoted string

+> A Gantt chart is a type of bar chart, first developed by Karol Adamiecki in 1896, and independently by Henry Gantt in the 1910s, that illustrates a project schedule and the amount of time it would take for any one project to finish. Gantt charts illustrate number of days between the start and finish dates of the terminal elements and summary elements of a project.
+ 
+ ## A note to users
+ Gannt Charts will record each scheduled task as one continuous bar that extends from the left to the right. The x axis represents time and the y records the different tasks and the order in which they are to be completed.   
+ 
+ It is important to remember that when a date, day or collection of dates specific to a task are "excluded", the Gannt Chart will accomodate those changes by extending an equal number of day, towards the right, not by creating a gap inside the task.
+ As shown here ![](https://github.com/NeilCuzon/mermaid/blob/develop/docs/img/Gantt-excluded-days-within.png)
+ 
+ However, if the excluded date/s is between two tasks that are set to start consecutively, the excluded dates will be skipped graphically and left blank, and the following task will begin after the end of the excluded date/s.   
+ As shown here ![](https://github.com/NeilCuzon/mermaid/blob/develop/docs/img/Gantt-long-weekend-look.png)
+ 
+ A Gantt chart is useful for tracking the amount of time it would take before a project is finished, but it can also be used to graphically represent "non-working days, with a few tweaks. 
+ 
+Mermaid can render Gantt diagrams as SVG, PNG or a MarkDown link that can be pasted into docs.
