-### Configuration
+### Package build
+<pre>
+docker build -t arvados/fpm .
+docker run -v$PWD:$PWD -w $PWD arvados/fpm make packages
+</pre>
+
+### Build time configuration
You can customize project global variables using env variables. Default values are placed in the `.env` file.
Example:
```
-REACT_APP_ARVADOS_API_HOST=localhost:8000 yarn start
+REACT_APP_ARVADOS_CONFIG_URL=config.json yarn build
+```
+
+### Run time configuration
+The app will fetch runtime configuration when starting. By default it will try to fetch `/config.json`. You can customize this url using build time configuration.
+
+Currently this configuration schema is supported:
```
+{
+ "API_HOST": "string",
+ "VOCABULARY_URL": "string",
+ "FILE_VIEWERS_CONFIG_URL": "string",
+}
+```
+
+#### API_HOST
+
+The Arvados base URL.
+
+The `REACT_APP_ARVADOS_API_HOST` environment variable can be used to set the default URL if the run time configuration is unreachable.
+
+#### VOCABULARY_URL
+Local path, or any URL that allows cross-origin requests. See
+[Vocabulary JSON file example](public/vocabulary-example.json).
+
+To use the URL defined in the Arvados cluster configuration, remove the entire `VOCABULARY_URL` entry from the runtime configuration. Found in `/config.json` by default.
+
+### FILE_VIEWERS_CONFIG_URL
+Local path, or any URL that allows cross-origin requests. See:
+
+[File viewers config file example](public/file-viewers-example.json)
+
+[File viewers config scheme](src/models/file-viewers-config.ts)
+
+To use the URL defined in the Arvados cluster configuration, remove the entire `FILE_VIEWERS_CONFIG_URL` entry from the runtime configuration. Found in `/config.json` by default.
