 ## Installation/Update
 
 This app is supposed to work on the two latest Nextcloud versions.
@@ -52,14 +53,32 @@ Please make sure you have installed the following dependencies: `make, which, ta
 
 Instead of setting everything up manually, you can just [download the nightly build](https://github.com/nextcloud/deck/releases/tag/nightly) instead. These builds are updated every 24 hours, and are pre-configured with all the needed dependencies.
 
+## Performance limitations
+
+Deck is not yet ready for intensive usage.
+A lot of database queries are generated when the number of boards, cards and attachments is high.
+For example, a user having access to 13 boards, with each board having on average 100 cards,
+and each card having on average 5 attachments,
+would generate 6500 database queries when doing the file related queries
+which would increase the page loading time significantly.
+
+Improvements on Nextcloud server and Deck itself will improve the situation.
+
 ## Developing
 
+### Nextcloud environment
+
+You need to setup a [development environment](https://docs.nextcloud.com/server/latest/developer_manual//getting_started/devenv.html) of the current nextcloud version. You can also alternatively install & run the [nextcloud docker container](https://github.com/juliushaertl/nextcloud-docker-dev).
+After the finished installation, you can clone the deck project directly in the `/[nextcloud-docker-dev-dir]/workspace/server/apps/` folder. 
+
 ### PHP
 
 Nothing to prepare, just dig into the code.
 
 ### JavaScript
 
+This requires at least Node 16 and npm 7 to be installed.
+
 Deck requires running a `make build-js` to install npm dependencies and build the JavaScript code using webpack. While developing you can also use `make watch` to rebuild everytime the code changes.

+### 6. Import boards
+
+Importing can be done using the API or the `occ` `deck:import` command.
+
+Comments with more than 1000 characters are placed as attached files to the card.
+
+It is possible to import from the following sources:
+
+#### Trello JSON
+
+Steps:
+* Create the data file
+  * Access Trello
+  * go to the board you want to export
+  * Follow the steps in [Trello documentation](https://help.trello.com/article/747-exporting-data-from-trello-1) and export as JSON
+* Create the configuration file
+* Execute the import informing the import file path, data file and source as `Trello JSON`
+
+Create the configuration file respecting the [JSON Schema](https://github.com/nextcloud/deck/blob/master/lib/Service/Importer/fixtures/config-trelloJson-schema.json) for import `Trello JSON`
+
+Example configuration file:
+```json
+{
+    "owner": "admin",
+    "color": "0800fd",
+    "uidRelation": {
+        "johndoe": "johndoe"
+    }
+}
+```
+
+**Limitations**:
+
+Importing from a JSON file imports up to 1000 actions. To find out how many actions the board to be imported has, identify how many actions the JSON has.
+
+#### Trello API
+
+Import using API is recommended for boards with more than 1000 actions.
+
+Trello makes it possible to attach links to a card. Deck does not have this feature. Attachments and attachment links are added in a markdown table at the end of the description for every imported card that has attachments in Trello.
+
+* Get the API Key and API Token [here](https://developer.atlassian.com/cloud/trello/guides/rest-api/api-introduction/#authentication-and-authorization)
+* Get the ID of the board you want to import by making a request to:
+https://api.trello.com/1/members/me/boards?key={yourKey}&token={yourToken}&fields=id,name
+
+  This ID you will use in the configuration file in the `board` property
+* Create the configuration file
+
+Create the configuration file respecting the [JSON Schema](https://github.com/nextcloud/deck/blob/master/lib/Service/Importer/fixtures/config-trelloApi-schema.json) for import `Trello JSON`
+
+Example configuration file:
+```json
+{
+    "owner": "admin",
+    "color": "0800fd",
+    "api": {
+        "key": "0cc175b9c0f1b6a831c399e269772661",
+        "token": "92eb5ffee6ae2fec3ad71c777531578f4a8a08f09d37b73795649038408b5f33"
+    },
+    "board": "8277e0910d750195b4487976",
+    "uidRelation": {
+        "johndoe": "johndoe"
+    }
+}
+```
+
+### 7. Search
 
 Deck provides a global search either through the unified search in the Nextcloud header or with the inline search next to the board controls.
 This search allows advanced filtering of cards across all board of the logged in user.
 
 For example the search `project tag:ToDo assigned:alice assigned:bob` will return all cards where the card title or description contains project **and** the tag ToDo is set **and** the user alice is assigned **and** the user bob is assigned.

+## Implement import
+
+* Create a new importer class extending `ABoardImportService`
+* Create a listener for event `BoardImportGetAllowedEvent` to enable your importer.
+  > You can read more about listeners on [Nextcloud](https://docs.nextcloud.com/server/latest/developer_manual/basics/events.html?highlight=event#writing-a-listener) doc.
+
+  Example:
+
+```php
+class YourCustomImporterListener {
+    public function handle(Event $event): void {
+        if (!($event instanceof BoardImportGetAllowedEvent)) {
+            return;
+        }
+
+        $event->getService()->addAllowedImportSystem([
+            'name' => YourCustomImporterService::$name,
+            'class' => YourCustomImporterService::class,
+            'internalName' => 'YourCustomImporter'
+        ]);
+    }
+}
+```
+  * Register your listener on your `Application` class like this:
+```php
+$dispatcher = $this->getContainer()->query(IEventDispatcher::class);
+$dispatcher->registerEventListener(
+    BoardImportGetAllowedEvent::class,
+    YourCustomImporterListener::class
+);
+```
+* Use the `lib/Service/Importer/Systems/TrelloJsonService.php` class as inspiration
