+# 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.

-## Special note regarding version 8.2
+:trophy: _"The most exciting use of technology"_ - [JS Open Source Awards (2019)](https://osawards.com/javascript/#nominees)
 
-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:
-
-⚠️ **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 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'
-    });
-```
-
-**🖖 Keep a steady pulse: mermaid needs more Collaborators [#866](https://github.com/knsv/mermaid/issues/866)**
-
-![banner](./img/header.png)
-
-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 nomiated and won the JS Open Source Awards (2019) in the catory The most existing 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.
-
-

 In version 8.2 a security improvement was introduced. A securityLevel configuration was introduced wich sets the level of trust to be used on the parsed diagrams.

+# 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.

+## 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.
+
+#### 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 is it optional:
+
+- `+`	Public
+- `-`	Private
+- `#`	Protected
+- `~`	Package
+
+Mermaid distinguishes between attributes and functions/methods based on if the **parenthesis** `()` are present or not. The one with `()` are treated as functions/methods, and others as attributes.
+
+There are two ways to define the members of a class, and regardless of the 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 : +withdrawl(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)
+    +withdrawl(amount)
+}
+```
+```mermaid
+    classDiagram
+    class BankAccount{
+        +String owner
+        +BigDecimal balance
+        +deposit(amount)
+        +withdrawl(amount)
+}```
+
+## 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 
+
+<!--- TODO ..>  Dependency--->
+```
+classDiagram
+classA <|-- classB
+classC *-- classD
+classE o-- classF
+classG <-- classH
+classI <.. classJ
+classK .. classL
+
+```
+
+```mermaid
+classDiagram
+classA <|-- classB
+classC *-- classD
+classE o-- classF
+classG <-- classH
+classI <.. classJ
+classK .. classL
+
+```
+We can use the arrowheads in opposite directions as well :
+```
+classDiagram
+classA --|> classB
+classC --* classD
+classE --o classF
+classG <--> classH
+classI ..> classJ
+classK .. classL
+
+```
+
+```mermaid
+classDiagram
+classA --|> classB
+classC --* classD
+classE --o classF
+classG <--> classH
+classI ..> classJ
+classK .. classL
+
+
+```
+## 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`        zeor 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
+}
+```
+
+
+
+## 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
+
+### Styling Classes used
+
+Class               | Description
+---                 | ---

+g.classGroup rect   | Styles for class diagram rectangle 
+g.classGroup line   | Styles for class diagram line
+.classLabel .box    | Styles for class label box
+.classLabel .label  | Styles for class label text
+composition         | Styles for componsition arrow head and arrow line
+aggregation         | Styles for aggregation arrow head and arrow line(dashed or solid)
+dependency          | Styles for dependency arrow head and arrow line

+# Pie chart diagrams

+> A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801

+# State diagrams
+
+> "A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems. State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction." Wikipedia
+
+Mermaid can render state diagrams. The syntax tries to be compliant with the syntax used in plantUml as this will make it easier for users to share diagrams between mermaid and plantUml.
+
+```markdown
+stateDiagram
+    [*] --> Still
+    Still --> [*]
+
+    Still --> Moving
+    Moving --> Still
+    Moving --> Crash
+    Crash --> [*]
+```
+
+```mermaid
+stateDiagram
+    [*] --> Still
+    Still --> [*]
+
+    Still --> Moving
+    Moving --> Still
+    Moving --> Crash
+    Crash --> [*]
+```
+
+In state diagrams systems are described in terms of its states and how the systems state can change to another state via a transitions. The example diagram above shows three states **Still**, **Moving** and **Crash**. You start in the state of Still. From Still you can change the state to Moving. In Moving you can change the state either back to Still or to Crash. There is no transition from Still to Crash.
+
+## States
+
+A state can be declares in multiple ways. The simplest way is to define a state id as a description.
+
+```markdown
+stateDiagram
+    s1
+```
+
+```mermaid
+stateDiagram
+    s1
+```
+
+Another way is by using the state keyword with a description as per below:
+
+```markdown
+stateDiagram
+    state "This is a state description" as s2
+```
+
+```mermaid
+stateDiagram
+    state "This is a state description" as s2
+```
+
+Another way to define a state with a description is to define the state id followed by a colon and the description:
+
+```markdown
+stateDiagram
+    s2 : This is a state description
+```
+
+```mermaid
+stateDiagram
+    s2 : This is a state description
+```
+
+## Transitions
+
+Transitions are path/edges when one state passes into another. This is represented using text arrow, "\-\-\>".
+
+When you define a transition between two states and the states are not already defined the undefined states are defined with the id from the transition. You can later add descriptions to states defined this way.
+
+```markdown
+stateDiagram
+    s1 --> s2
+```
+
+```mermaid
+stateDiagram
+    s1 --> s2
+```
+
+It is possible to add text to a transition. To describe what it represents.
+
+```markdown
+stateDiagram
+    s1 --> s2: A transition
+```
+
+```mermaid
+stateDiagram
+    s1 --> s2: A transition
+```
+
+## Start and End
+
+There are two special states indicating the start and stop of the diagram. These are written with the [\*] syntax and the direction of the transition to it defines it either as a start or a stop state.
+
+```markdown
+stateDiagram
+    [*] --> s1
+    s1 --> [*]
+```
+
+```mermaid
+stateDiagram
+    [*] --> s1
+    s1 --> [*]
+```
+
+## Composite states
+
+In a real world use of state diagrams you often end up with diagrams that are multi-dimensional as one state can
+have several internal states. These are called composite states in this terminology.
+
+In order to define a composite state you need to use the state keyword followed by and id and the body of the composite state between \{\}. See the example below:
+
+```markdown
+stateDiagram
+    [*] --> First
+    state First {
+        [*] --> second
+        second --> [*]
+    }
+```
+
+```mermaid
+stateDiagram
+    [*] --> First
+    state First {
+        [*] --> second
+        second --> [*]
+    }
+```
+
+You can do this in several layers:
+
+```markdown
+stateDiagram
+    [*] --> First
+
+    state First {
+        [*] --> Second
+
+        state Second {
+            [*] --> second
+            second --> Third
+
+            state Third {
+                [*] --> third
+                third --> [*]
+            }
+        }
+    }
+```
+
+```mermaid
+stateDiagram
+    [*] --> First
+
+    state First {
+        [*] --> Second
+        state Second {
+            [*] --> second
+            second --> Third
+
+            state Third {
+                [*] --> third
+                third --> [*]
+            }
+        }
+    }
+```
+
+You can also define transitions also between composite states:
+
+```markdown
+stateDiagram
+    [*] --> First
+    First --> Second
+    First --> Third
+
+    state First {
+        [*] --> fir
+        fir --> [*]
+    }
+    state Second {
+        [*] --> sec
+        sec --> [*]
+    }
+    state Third {
+        [*] --> thi
+        thi --> [*]
+    }
+```
+
+```mermaid
+stateDiagram
+    [*] --> First
+    First --> Second
+    First --> Third
+
+    state First {
+        [*] --> fir
+        fir --> [*]
+    }
+    state Second {
+        [*] --> sec
+        sec --> [*]
+    }
+    state Third {
+        [*] --> thi
+        thi --> [*]
+    }
+```
+
+*You can not define transitions between internal states belonging to different composite states*
+
+## Forks
+
+It is possible to specify a fork in the diagram using <<fork>> <<join>>.
+
+```markdown
+   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 --> [*]
+```
+
+```mermaid
+   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 --> [*]
+
+```
+
+## Notes
+
+Sometimes nothing says it better then a Post-it note. That is also the case in state diagrams.
+
+Here you can choose to put the note to the *right of* or to the *left of* a node.
+
+```markdown
+    stateDiagram
+        State1: The state with a note
+        note right of State1
+            Important information! You can write
+            notes.
+        end note
+        State1 --> State2
+        note left of State2 : This is the note to the left.
+```
+
+```mermaid
+    stateDiagram
+    State1: The state with a note
+    note right of State1
+      Important information! You can write
+      notes.
+    end note
+    State1 --> State2
+    note left of State2 : This is the note to the left.
+
+```
+
+## Concurrency
+
+As in plantUml you can specify concurrency using the -- symbol.
+
+```markdown
+    stateDiagram
+        [*] --> Active
+
+        state Active {
+            [*] --> NumLockOff
+            NumLockOff --> NumLockOn : EvNumLockPressed
+            NumLockOn --> NumLockOff : EvNumLockPressed
+            --
+            [*] --> CapsLockOff
+            CapsLockOff --> CapsLockOn : EvCapsLockPressed
+            CapsLockOn --> CapsLockOff : EvCapsLockPressed
+            --
+            [*] --> ScrollLockOff
+            ScrollLockOff --> ScrollLockOn : EvCapsLockPressed
+            ScrollLockOn --> ScrollLockOff : EvCapsLockPressed
+        }
+```
+
+```mermaid
+    stateDiagram
+        [*] --> Active
+
+        state Active {
+            [*] --> NumLockOff
+            NumLockOff --> NumLockOn : EvNumLockPressed
+            NumLockOn --> NumLockOff : EvNumLockPressed
+            --
+            [*] --> CapsLockOff
+            CapsLockOff --> CapsLockOn : EvCapsLockPressed
+            CapsLockOn --> CapsLockOff : EvCapsLockPressed
+            --
+            [*] --> ScrollLockOff
+            ScrollLockOff --> ScrollLockOn : EvCapsLockPressed
+            ScrollLockOn --> ScrollLockOff : EvCapsLockPressed
+        }
+```
