+## About the project
+
+Ethereum wallet application framework for Nano S and Nano X.  
+Ledger Blue is not maintained anymore, but the app can still be compiled for this target using the branch [`blue-final-release`](https://github.com/LedgerHQ/app-ethereum/tree/blue-final-release).
+
+## Documentation
 
 This app follows the specification available in the `doc/` folder.
 
 To compile it and load it on a device, please check out our [developer portal](https://developers.ledger.com/docs/nano-app/introduction/).
 
-# Plugins
+### Plugins
 
-This app support external plugins. More info in [doc/ethapp_plugin.asc](https://github.com/LedgerHQ/app-ethereum/blob/master/doc/ethapp_plugins.asc). If you wish to have a look at an existing plugin, feel free to check out the [Boilerplate plugin](https://github.com/LedgerHQ/app-plugin-boilerplate).
+We have the concept of plugins in the ETH app.

-# Testing
+## Testing
 
 Testing is done via the open-source framework [zemu](https://github.com/Zondax/zemu).
 
-## Running tests
+### Requirement
 
-First [install yarn](https://classic.yarnpkg.com/en/docs/install/#debian-stable).
+- [nodeJS](https://github.com/nvm-sh/nvm)
-Open `tests/build_local_test_elfs.sh` and add your BOLOS SDKs path to `NANOS_SDK` and `NANOX_SDK`.
+- [yarn](https://classic.yarnpkg.com/lang/en/docs/install/#debian-stable)
-This helper script will build the applications required by the test suite and move them at the right place.
+- [build environnement](https://github.com/LedgerHQ/ledger-app-builder/blob/master/Dockerfile)
-```
-cd tests
-./build_local_test_elfs.sh
-```
-Then you can install the project by simply running:
-```
-cd ..
-make test
-```
-This will run `make install_tests` and `make run_tests`
 
-To run a specific tests (here the send test):
+#### Build the applications required by the test suite  
-```
-cd tests
-jest --runInBand --detectOpenHandles src/send.test.js
-```
 
-Make sure you're in the `tests` folder before running `jest` or `yarn test`.
+1. Add your BOLOS SDKs path to:
+    - `NANOS_SDK` and `NANOX_SDK`
+
+2. Go to the `tests` folder and run `./build_local_test_elfs.sh`
+    - ```sh
+        cd tests
+        # This helper script will build the applications required by the test suite and move them at the right place.
+        yarn install
+        ./build_local_test_elfs.sh
+      ```
+
+### Running all tests
+#### With Makefile
+
+1. Then you can install the project by simply running on the `root` of the repo:
+    - ```sh
+        make test
+      ```
+    - This will run `make install_tests` and `make run_tests`
+
+#### With yarn
+
+1. Go to the `tests` folder and run:
+    - ```sh
+        yarn test
+      ```
+
+### Running a specific tests
+
+1.  Go to the `tests` folder and run:
+    - ```sh
+        yarn jest --runInBand --detectOpenHandles {YourTestFile}
+      ```
+2.  For example with the `send test`:
+    - ```sh
+        yarn jest --runInBand --detectOpenHandles src/send.test.js
+      ```

 To add tests, copy one of the already existing test files in `tests/src/`.

-### Update binaries
+#### Update binaries
 
 Don't forget to update the binaries in the test folder. To do so, compile with those environement variables:
-```
+
+```sh
 make DEBUG=1 ALLOW_DATA=1
 ```
 
 Then copy the binary to the `tests/elfs` folder (in this case, compiled with SDK for nanoS):
-```
+
+```sh
 cp bin/app.elf tests/elfs/ethereum_nanos.elf
 ```
 
 Repeat the operation for a binary compiled with nanoX SDK and change for `ethereum_nanox.elf`.
