+
+## Switch to the installation user
+
+Switch to the username you've used throughout the installation process.
+
+```sh
+su <USERNAME>
+```
+
+For example, if you used the username `lgtn` it'll look like the following command:
+
+```sh
+su lgtn
+```
+
+## Change directory to the source code
+
+If you have installed it via the recommended process or instructions, then the default location where the [source code](https://github.com/fleek-network/lightning) is stored is `~/fleek-network/lightning`.
+
+```sh
+cd ~/fleek-network/lightning
+```
+
+:::tip
+Notice that we use `~`, which refers to `$HOME`. You must use the username used for the installation process. For example, on [Ubuntu](/docs/node/requirements#server) if you used the username `lgtn`, the pathname for `$HOME` is `/home/lgtn`.
+:::
+
+## Pull the latest changes
+
+To pull the latest changes use the `git pull` command, as follows:
+
+```sh
+git pull origin testnet-alpha-0
+```
+
+:::tip
+We are using the branch named `testnet-alpha-0`, which is specific to the early testnet launch. Change to the correct branch name according to needs. For example, in the future the mainnet version will go on branch name `main`.
+:::
+
+## Build binary from the source
+
+To build the binary from the source code, we execute the cargo build command:
+
+```sh
+cargo +stable build --release
+```
+
+### Restart the service
+
+Once the cargo build process completes, you have to restart the service, as follows:
+
+```sh
+systemctl restart lightning
+```
+
+:::tip
+If you have installed the Fleek Network lightning manually, the [installation instructions](/docs/node/install#systemd-service-setup) recommended setting up a systemd service for the Fleek Network process. If you haven't, you're advised to check the instructions provided.
+:::
+
+### Health checkup
+
+Do a quick health check by running:
+
+```sh
+curl -w "\p" localhost:4069/health
+```
+
+If successful, you should get the response `OK`, as follows:
+
+```sh
+OK
+```
