+# Dashboard
+
+Without any doubt, this is the principal resource of Perses.
+
+A `Dashboard` belongs to a `Project`. See the [project documentation](./project.md) to see how to create a project.
+
+It is defined like this:
+
+```yaml
+kind: "Dashboard"
+metadata:
+  name: <string>
+  project: <string>
+spec: <dashboard_specification>
+```
+
+## Dashboard specification
+
+```yaml
+# Metadata.name has some restrictions. For example, you can't use space here.
+# `display` allows to provide a rich name and a description for your dashboard.
+[ display: <Display specification> ]
+
+# `datasources` is a map where the key is the reference of the datasource. The value is the actual datasource definition.
+# A datasource can be referenced by the different panels and/or variables.
+datasources:
+  [ <string>: <Datasource specification> ]
+
+# `variables` is the list of dashboard variables. A variable can be referenced by the different panels and/or by other variables.
+variables:
+  - [ <Variable specification> ]
+
+# `panels` is a map where the key is the reference of the panel. The value is the actual panel definition that describes
+# the kind of chart this panel is using. A panel can only hold one chart.
+panels:
+  [ <string>: <Panel specification> ]
+
+# `layouts` is the list of layouts. A layout describes how to display the list of panels. 
+# Indeed, in Perses the definition of a panel is uncorrelated from the definition of where to position it.
+layouts:
+  - <Layout specification>
+
+# `duration` is the default time range to use on the initial load of the dashboard.
+[ duration: <duration> ]
+
+# `refreshInterval` is the default refresh interval to use on the initial load of the dashboard.
+[ refreshInterval: <duration> ]
+```
+
+A dashboard in its minimal definition only requires a panel and a layout.
+
+### Display specification
+
+This is the way to provide a rich name and a description for your dashboard. There is no restriction about the type of
+characters you can use here.
+
+```yaml
+# The new name of the dashboard. If set, it will replace `metadata.name` in the dashboard title in the UI.
+# Note that it cannot be used when you are querying the API. Only `metadata.name` can be used to reference the dashboard.
+# This is just for display purpose.
+[ name: <string> ]
+
+# The description of the dashboard.
+[ description: <string> ]
+```
+
+### Datasource specification
+
+See the [datasource](./datasource.md) documentation.
+
+### Variable specification
+
+See the [variable](./variable.md) documentation.
+
+### Panel specification
+
+```yaml
+kind: "Panel"
+spec:
+  display: <Display specification>
+
+  # `plugin` is where you define the chart type to use.
+  # The chart type chosen should match one of the chart plugins known to the Perses instance.
+  plugin: <Panel Plugin specification>
+
+  # `queries` is the list of queries to be executed by the panel. The available types of query are conditioned by the type of chart & the type of datasource used.
+  queries:
+    - [ <Query specification> ]
+```
+
+#### Panel Plugin specification
+
+```yaml
+# `kind` is the plugin type of the panel. For example, `TimeSeriesChart`.
+kind: <string>
+
+# `spec` is the actual definition of the panel plugin. Each `kind` comes with its own `spec`.
+spec: <Plugin specification>
+```
+
+See the [Panel plugins](../plugins/panels.md) documentation to know more about the different panels supported by Perses.
+
+#### Query specification
+
+```yaml
+# kind` is the type of the query. For the moment we only support `TimeSeriesQuery`.
+kind: <string>
+spec:
+  plugin: <Query Plugin specification>
+```
+
+##### Query Plugin specification
+
+```yaml
+# `kind` is the plugin type matching the type of query. For example, `PrometheusTimeSeriesQuery` for the query type `TimeSeriesQuery`.
+kind: <string>
+
+# `spec` is the actual definition of the query. Each `kind` comes with its own `spec`.
+spec: <Plugin specification>
+```
+
+Perses supports only Prometheus for the `TimeSeriesQuery` for the moment.
+Please look at the [Prometheus documentation](../plugins/prometheus.md#datasource) to know the spec for the `PrometheusTimeSeriesQuery`.
+
+### Layout specification
+
+```yaml
+kind: "Grid"
+spec:
+  [ display: <Grid Display specification> ]
+  items:
+    [ - <Grid Item specification> ]
+```
+
+Example:
+
+```yaml
+kind: "Grid"
+spec:
+  display:
+    title: "Row 1"
+    collapse:
+      open: true
+  items:
+    - x: 0
+      y: 0
+      width: 2
+      height: 3
+      content:
+        "$ref": "#/spec/panels/statRAM"
+    - x: 0
+      y: 4
+      width: 2
+      height: 3
+      content:
+        $ref": "#/spec/panels/statTotalRAM"
+```
+
+### Grid Display specification
+
+```yaml
+title: <string>
+collapse:
+  open: <boolean>
+```
+
+### Grid Item specification
+
+```yaml
+x: <int>
+y: <int>
+width: <int>
+height: <int>
+content:
+  "$ref": <json_panel_ref>
+```
+
