Improves documentation
* Describes better available source tree sharing method (between xds-agent and xds-server), and which to prefer depending on the deployment setup. * Gives indication about how to pass RSYNC_TARGET and RSYNC_PREFIX env vars to the helloworld-native-application build process. * Swap chapter order (build before config) Change-Id: Ie4c22f277a59b0405744d71b0fadff67c5d5d025 Signed-off-by: Johann CAHIER <johann.cahier@iot.bzh>

+# Configuration
+
+xds-agent configuration is driven by a JSON config file.
+
+The tarball mentioned in previous section includes this file with default settings.
+
+Here is the logic to determine which conf file will be used:
+
+1. from command line option: `--config myConfig.json`
+1. `$HOME/.xds/agent/agent-config.json` file
+1. `/etc/xds/agent/agent-config.json` file
+
+Supported fields in configuration file are (all fields are optional and example
+below corresponds to the default values):
+
+- **httpPort** : http port of agent REST interface
+- **webAppDir** : location of client webapp / dashboard (default: webapp/dist)
+- **logsDir** : directory to store logs (eg. syncthing output)
+- **xdsServers** : an array of xds-server object
+ - **xdsServers.url**: url of xds-server to connect to
+- **syncthing**: a object defining syncthing settings
+ - **syncthing.binDir** : syncthing binaries directory (default: executable directory)
+ - **syncthing.home"** : syncthing home directory (usually .../syncthing-config)
+ - **syncthing.gui-address** : syncthing gui url (default <http://localhost:8386>)
+ - **syncthing.gui-apikey** : syncthing api-key to use (default auto-generated)
+
+```json
+{
+ "httpPort": "8800",
+ "webAppDir": "./www",
+ "logsDir": "${HOME}/.xds/agent/logs",
+ "xdsServers": [
+ {
+ "url": "http://localhost:8000"
+ }

+ "gui-address": "http://localhost:8386",
