In the Orchard CMS, modules and themes are important tools for extending and customizing an application. Every module and theme is required to have a manifest, which is a text file named module.txt or theme.txt that resides in the root folder of the associated module or theme. A manifest stores metadata that Orchard uses to describe modules and themes to the system, such as name, version, description, author, and tags.
This topic is a reference for manifest files. If you create a custom module or theme, or if you write code that accesses modules or themes, you must understand the metadata fields in a manifest. The data in a manifest is structured into name-value pairs in the form
Field Name: Value.
The following sections describe the available fields in a manifest for themes and for modules. Because a theme is a type of module, many of the same metadata fields occur in both theme manifests and module manifests.
Module manifest fields
The manifest for a module should be called
module.txt and should be located in the root of the project.
A module's manifest is made up of an overall description of the package itself and then an optional repeating section describing each of the individual features.
The module can be comprised of a default single feature or a group of individually defined features. This allows module developers to specify separate areas of the module and allow users to enable them on a per-feature basis.
Main module.txt fields
Some of the fields may be overridden if a module defines multiple features. These are detailed in the
Features: sub-section fields table below.
Provides a human-readable name for a module.
If a name is provided, it will be used as the module's display name in the Orchard Gallery and in the Orchard UI.
If a name is not provided in the manifest, the ID is used instead.
Note: The ID of a module is generated internally from the name of the module's folder and is used for programmatic references to the module. For example, if the module is located in
Provides a name that is used to build more readable URLs for routing purposes compared to URLs that are based on module names or ID values.
If a path is not provided, Orchard builds URLs based on the module's name (if one is provided) or on the ID. However, module names often have spaces, and ID values often have "." characters, neither of which result in very readable URLs.
For example, for the
Note: If specified, the Path must be a valid URL segment. If you're unsure what this means the best bet is to stick with letters and numbers with no spaces.
Possible values are
A value that indicates whether request validation is enabled for a module.
The developer of the module.
This can be an organization, individual, or a list of individuals.
The URL for the website of the module developer.
The version number of the module in SemVer format.
The version information is displayed in the Orchard Gallery and in the Orchard UI.
It is also used to determine whether an update is available.
The minimum version of Orchard CMS that the module has been tested against.
A brief summary of what the module does.
The description is used in the Orchard Gallery and in the Orchard UI.
Will be overridden by the

Defaults to uncategorized.
This field groups the module together in the Modules page of the Orchard admin dashboard. Related modules which have the same category are displayed together. The category field can be assigned one category. To aid in discoverability, module developers should review the Modules page of the Orchard admin dashboard and choose a related category from existing categories. If a relevant category doesn't exist modules can freely define a new category within this field.
A comma-separated lists of tags for the module.
The tags field allow users to find related modules in the Orchard Gallery.
A description of the default feature in a module.
If the module has only a single feature, use either the
If the module has multiple features and one of the features is the default, use the

A special repeating section of the manifest which allows a module to define multiple features within a module.
Supports several sub-fields as described by the table in the next section.
The features section should be placed at the end of the manifest.
Module.txt Features: sub-section fields
If a module provides multiple individual features within a single module then the repeating
Features: sub-section should be used. It allows module developers to specify separate manifest fields for each individual feature. These individual features can then be enabled and disabled separately by end users.
Features: field doesn't have any assigned value. It is a placemarker field that indicates the beginning of a repeating list of features.
Examples of the formatting to be used for this part of the manifest can be found in the next section.
Because the feature is already contained within the module ID module developers need to supply a unique ID for Orchard to use internally as a reference.
This is a special field. The line must begin with either a

Either the main manifest section should define this field or a single feature in the features sub-section should assign this field.
It should contain a description of the individual feature.
Defaults to uncategorized.
This field groups the feature together in the Modules page of the Orchard admin dashboard. Related features which have the same category are displayed together.
Each individual feature can be assigned one category, however the different features included in the module may have each have their own category to move that feature into the most relevant area of the admin dashboard.
To aid in discoverability, module developers should prefer to review the Modules page of the Orchard admin dashboard and choose a related category from existing categories. If a relevant category doesn't exist modules can freely define a new category within this field of the manifest.
Required if the feature has dependencies

Each individual feature should only define its own dependencies. If all features are defined in the

Module manifest examples
Listed below are the three different ways you can use the module manifest.

The Orchard.Alias module itself (defined as

Orchard.Alias but module developers can define independent features as well.

Theme manifest fields
A theme manifest can have the following fields:
|Name||Provides a human-readable name for a theme that is an alternative to using the theme's ID. The ID of a theme is the name of the theme's folder in the virtual base path (the default virtual base path is ~/Themes), and is used for programmatic references. For example, for a theme whose ID is
|Description||A brief summary of a theme's appearance and layout details. The description is used in the Orchard Gallery and in the Orchard UI.|
