+Configuration through environment variables may also be defined in a file that

-using the `--list` option. This option lists all existing projects ID:
-
-```bash
-./bin/xds-exec --list
+Project ID you want to build
-List of existing projects:
- CKI7R47-UWNDQC3_myProject
- CKI7R47-UWNDQC3_test2
- CKI7R47-UWNDQC3_test3
-```
+`--config|-c` option or `XDS_CONFIG` env variable
-Now to refer your project, just use --id option or use `XDS_PROJECT_ID`
-environment variable.
+Env config file to source on startup
-You are now ready to use XDS to for example cross build your project.
-Here is an example to build a project based on CMakefile:
+`--log|-l` option or `XDS_LOGLEVEL` env variable
-```bash
-# Add xds-exec in the PATH
-export PATH=${PATH}:/opt/AGL/agl-xds-exec
+Logging level, supported levels are:
-# Go into your project directory
-cd $MY_PROJECT_DIR
+* panic,
+* fatal,
+* error,
+* warn,
+* info,
+* debug
-# Create a build directory
-xds-exec --id=CKI7R47-UWNDQC3_myProject --sdkid=poky-agl_aarch64_4.0.1 --url=http://localhost:8000 -- mkdir build
+Default level is "error".
-# Generate build system using cmake
-xds-exec --id=CKI7R47-UWNDQC3_myProject --sdkid=poky-agl_aarch64_4.0.1 --url=http://localhost:8000 -- cd build && cmake ..

-xds-exec --id=CKI7R47-UWNDQC3_myProject --sdkid=poky-agl_aarch64_4.0.1 --url=http://localhost:8000 -- cd build && make all
-```
+Relative path into project
-To avoid to set project id, xds server url, ... at each command line, you can
-define these settings as environment variable within an env file and just set
-`--config` option or source file before executing xds-exec.
+`sdkid` option or `XDS_SDK_ID` env variable **(mandatory)**
-For example, the equivalence of above command is:
+Cross Sdk ID to use to build project
-```bash
-cat > config.env << EOF
- export XDS_SERVER_URL=localhost:8000
- export XDS_PROJECT_ID=CKI7R47-UWNDQC3_myProject
- export XDS_SDK_ID=poky-agl_aarch64_4.0.1
-EOF
-
-xds-exec --config config.env -- mkdir build
-
-# Or sourcing env file
-source config.env
-xds-exec -- cd build && cmake ..
-xds-exec -- cd build && make all
-```
+`timestamp|-ts` option or `XDS_TIMESTAMP` env variable
-### Using xds-exec within an IDE
+Prefix output with timestamp

-
-First the project you want to debug must be declared on an xds-server and this
-project may also has been built using this xds-server (see [xds-server](https://github.com/iotbzh/xds-server) for more details).
-
-So to debug it you need to know the xds-server url (eg. <http://xds-docker:8000>),
-you also need the project and sdk unique id. You can find these IDs in project
-page of XDS dashboard or you can get them from command line using the `--list`
-option.
-This option lists all existing projects ID:
-
-```bash
-XDS_SERVER_URL=http://xds-docker:8000 xds-gdb --list
-```
-
-Now to refer your project, just set `XDS_PROJECT_ID` and `XDS_SDK_ID` variables.
-
-You are now ready to use `xds-gdb` to for example cross debug your project.
-Here is an example to build and debug a project based on CMakefile and
-[AGL app-templates](https://git.automotivelinux.org/apps/app-templates/):
-
-```bash
-# Go into your project directory (for example helloworld-service)
-git clone https://github.com/iotbzh/helloworld-service.git
-cd helloworld-service
-
-# Declare your project on xds-server
-# <for now, you can only do this step using xds HTML dashboard (see xds-server doc)>
-
-# Define XDS config
-cat <<EOF >./xds-config.env
-XDS_SERVER_URL=http://xds-docker:8000
-XDS_PROJECT_ID=IW7B4EE-DBY4Z74_myProject
-XDS_SDK_ID=poky-agl_aarch64_4.0.1

-
-# Tell to xds-exec and xds-gdb which is your config file
-export XDS_CONFIG=../xds-config.env
