+
+
+An AsgardCMS module which enabled tagging of any entity with ease.
+
+## Installation
+
+### Composer
+
+```
+composer require asgardcms/tag-module
+```
+
+### Migrations
+
+Run the migrations for the tag module
+
+```
+php artisan module:migrate tag
+```
+
+### Permissions
+
+Go to the Admin role, and give yourself the permissions for the Tag Module.
+
+
+## Usage
+
+Any of you entities can have tags attached to it. To enable this your entity needs to implement an interface, use a trait and that's it.
+
+### 1. Add interface & trait on desired entity
+
+Your entity needs to implement the `Modules\Tag\Contracts\TaggableInterface` interface.
+
+In order for your entity to satisfy this interface it needs to use the following traits:
+
+- `Modules\Core\Traits\NamespacedEntity`
+- `Modules\Tag\Traits\TaggableTrait`
+
+Tags are organised by namespace. This is used in order to get the tags for a specific namespace on the display of the field. It also creates tags for that namespace if tags need to be created.
+ 
+By default the `TaggableTrait` will use the full namespace of your entity. However, you can specify a nicer / shorter namespace to use by using the static `$entityNamespace` property on your entity.
+ 
+Example:
+ 
+``` php
+protected static $entityNamespace = 'asgardcms/media';
+```
+ 
+### 2. Defining a new namespace to use for tags
+ 
+In your module Service Provider, `boot()` method, you now need to add the namespace it's going to use. This can be done using the `TagManager` interface.
+
+``` php
+$this->app[TagManager::class]->registerNamespace(new File());
+```
+
+And with this, the Tag Module is aware of the new namespace.
+
+### 3. Display the tag field on your views
+
+By using a custom blade directive you can include the tags field on your views. 
+
+- The first argument is the namespace to get the tags for.
+- (optional) Second argument is the entity to fetch the tags for (pre-filling the input if tags are present for given entity).
+- (optional) Third and last argument can be a view to use. This will override the default tags view with its input field.
+
+```` php
+@tags('asgardcms/media', $file)
+````
+
+### 4. Store tags
+
+In your repositories you need to call the `setTags()` method to persist the tags on your entity.
+
+``` php
+$file->setTags(array_get($data, 'tags'));
+```
+
+And that's all on how to use tags for your entities.
+ 
+## Convenience methods
+
+### Scope: `withTag()`
+
+Get all the entities with one of the given tag(s). Optionally specify the column on which to perform the search operation, defaults to the `slug` column.
+
+Example in your repository :
+
+``` php
+// Get all files with either of the 2 tags
+$files = $this->file->withTag(['your-first-tag', 'some-other-tag'])->get();
+```
+
+### Scope: `whereTag()`
+
+Get all the entities with the given tag(s). Optionally specify the column on which to perform the search operation, defaults to `slug` column.
+
+Example in your repository :
+
+``` php
+// Get all files with all given tags
+$files = $this->file->whereTag(['your-first-tag', 'some-other-tag'])->get();
+
+// Get all files with the given tag
+$files = $this->file->whereTag('your-first-tag')->get();
+```
+
+### `allTags()`: Get all the tags for the entity
+
+You can fetch all the tags for an entity by using the `allTags()` method.
+
+``` php
+$tags = $file->allTags();
+```
