Correct basic grammar in a few areas. 

I tried not to be too academic, but to me as a native English (Canadian) speaker and writer I have made some suggestions that include simple grammar corrections. Mostly I just added 's' where it needs to be.

MISP objects used in MISP system and can be used by other information sharing tools. MISP objects
are in addition to MISP attributes to allow advanced combinations of attributes. The creation of these objects
and their associated attributes are based on real cyber security use-cases and existing practices in information sharing.

A MISP object is described in a simple JSON file containing the following elements.
* **name** is the name of the your object.
* **meta-category** is the category where the object falls into. (such as file, network, financial, misc, internal...)
* **description** is a summary of the object description.
* **version** is the version number as a decimal value.
* **required** is an array containing the minimal required attributes to describe the object.
* **requiredOneOf** is an array containing the attributes where at least one need to be present to describe the object.
* **requiredOneOf** is an array containing the attributes where at least one needs to be present to describe the object.
* **attributes** contains another JSON object listing all the attributes composing the object.
Each attribute must contain a reference **misp-attribute** to reference an existing attribute definition in MISP (MISP attributes types are case-sensitive).

## How to contribute MISP objects?
Fork the project, create a new directory in the [objects directory](objects/) matching your object name. Objects must be composed
of existing MISP attributes. If you are missing a specific attributes, feel free to open an issue in the [MISP project](https://www.github.com/MISP/MISP).

We recommend to add a **text** attribute in a object to allow users to add comments or correlating text.

### Best practices when creating MISP object templates
- Use lower-case name without underscore or special characters (except minus) for the field names
- Use lower-case names without underscore or special characters (except minus) for the field names
- Add a description in the object template explaining the scope and use-cases of your object templates
- If the object is the mapping of an existing format, add a reference into the description of the object template
- `first-seen` and `last-seen` are not required in a object template as an object has those fields by default. If you need additional temporal information, add new specific field(s).

The aim is to allow a dynamic update of objects definition in operational distributed sharing systems like MISP. Security threats and their related indicators are quite dynamic, standardized formats are quite static and new indicators require a significant time before being standardized.
The MISP objects model allows to add new combined indicators format based on their usage without changing the underlying code base of MISP or other threat sharing platform using it. The definition of the objects can be then propagated along with the indicators itself.
