     9  # Finding and Using Modules
    10  
    11  The [Terraform Registry](https://registry.terraform.io) makes it simple to
    12  find and use modules.
    13  
    14  ## Finding Modules
    15  
    16  Every page on the registry has a search field for finding
    17  modules. Enter any type of module you're looking for (examples: "vault",
    18  "vpc", "database") and resulting modules will be listed. The search query
    19  will look at module name, provider, and description to match your search
    20  terms. On the results page, filters can be used further refine search results.
    21  
    22  By default, only [verified modules](/docs/registry/modules/verified.html)
    23  are shown in search results. Verified modules are reviewed by HashiCorp to
    24  ensure stability and compatibility. By using the filters, you may view unverified
    25  modules as well.
    26  
    27  ## Using Modules
    28  
    29  The Terraform Registry is integrated directly into Terraform. This makes
    30  it easy to reference any module in the registry. The syntax for referencing
    31  a registry module is `namespace/name/provider`. For example:
    32  `hashicorp/consul/aws`.
    33  
    34  When viewing a module on the registry on a tablet or desktop, usage instructions
    35  are shown on the right side. The screenshot below shows where to find these.
    36  You can copy and paste this to get started with any module. Some modules may
    37  have required inputs you must set before being able to use the module.
    38  
    39  ```hcl
    40  module "consul" {
    41    source = "hashicorp/consul/aws"
    42    version = "0.1.0"
    43  }
    44  ```
    45  
    46  ## Module Versions
    47  
    48  Each module in the registry is versioned. These versions syntactically must
    49  follow [semantic versioning](http://semver.org/). In addition to pure syntax,
    50  we encourge all modules to follow the full guidelines of semantic versioning.
    51  
    52  Terraform since version 0.11 will resolve any provided 
    53  [module version constraints](/docs/modules/usage.html#module-versions) and 
    54  using them is highly recommended to avoid pulling in breaking changes.
    55  
    56  Terraform from version 10.6 through to 0.11 had partial support for the registry 
    57  protocol, however will not honor version constraints and always download the
    58  latest version.
