As explained in dedicated page xref:develop:view_models_aka_cells.adoc[View Models (Cells)], a cell is an object that represent a fragment of your UI.
In order to define a cell, you need to create a class that inherits from `Decidim::ViewModel` in your module.
Cells classes are located in the `app/cells/decidim/<my_module>` directory, and named: `<my_cell>_cell.rb`.
For example, if you want to create a cell that renders a simple text:
```ruby
# frozen_string_literal: true
# app/cells/decidim/my_module/my_cell_cell.rb
module Decidim
module MyModule
class MyCellCell < Decidim::ViewModel
def show
render if condition?
end
private
def condition?
true
end
end
end
end
```
Then, you can render the cell in your view:
```erb
<%= cell("decidim/my_module/my_cell") =>
```
