+### Javascript
+
+All Javascript files are under [apps/block_scout_web/assets/js](https://github.com/poanetwork/blockscout/tree/master/apps/block_scout_web/assets/js) and the main file is [app.js](https://github.com/poanetwork/blockscout/blob/master/apps/block_scout_web/assets/js/app.js). This file imports all javascript used in the application. If you want to create a new JS file consider creating into [/js/pages](https://github.com/poanetwork/blockscout/tree/master/apps/block_scout_web/assets/js/pages) or [/js/lib](https://github.com/poanetwork/blockscout/tree/master/apps/block_scout_web/assets/js/lib), as follows:
+
+#### js/lib
+This folder contains all scripts that can be reused in any page or can be used as a helper to some component.
+
+#### js/pages
+This folder contains the scripts that are specific for some page.
+
+#### Redux
+This project uses Redux to control the state in some pages. There are pages that have things happening in real-time thanks to the Phoenix channels, e.g. Address page, so the page state changes a lot depending on which events it is listening. The redux is also used to load some contents asynchronous, see [async_listing_load.js](https://github.com/poanetwork/blockscout/blob/master/apps/block_scout_web/assets/js/lib/async_listing_load.js).
+
+To understand how to build new pages that need redux in this project, see the [redux_helpers.js](https://github.com/poanetwork/blockscout/blob/master/apps/block_scout_web/assets/js/lib/redux_helpers.js)

+## Tracing
+
+Blockscout supports tracing via
+[Spandex](http://git@github.com:spandex-project/spandex.git). Each application
+has its own tracer, that is configured internally to that application. In order
+to enable it, visit each application's `config/<env>.ex` and update its tracer
+configuration to change `disabled?: true` to `disabled?: false`. Do this for
+each application you'd like included in your trace data.
+
+Currently, only [Datadog](https://www.datadoghq.com/) is supported as a
+tracing backend, but more will be added soon.
+
+### DataDog
+
+If you would like to use DataDog, after enabling `Spandex`, set
+`"DATADOG_HOST"` and `"DATADOG_PORT"` environment variables to the
+host/port that your Datadog agent is running on. For more information on
+Datadog and the Datadog agent, see their
+[documentation](https://docs.datadoghq.com/).
+
+### Other
+
+If you want to use a different  backend, remove the
+`SpandexDatadog.ApiServer` `Supervisor.child_spec` from
+`Explorer.Application` and follow any instructions provided in `Spandex`
+for setting up that backend.

 ## Memory Usage
 
 The work queues for building the index of all blocks, balances (coin and token), and internal transactions can grow quite large.   By default, the soft-limit is 1 GiB, which can be changed in `apps/indexer/config/config.exs`:
