-```bash
+As a result of the [research](https://github.com/ryssroad/fleek-aarch64-build) by the community member [ryssroad](https://github.com/ryssroad), the following solution was shared.
+
+Open the `cargo.toml` file in `~/fleek-network/lightning/Cargo.toml` and find the `lto` key.
+
+```sh
+lto = true
+```
+
+Change the `lto` key value from `true` to `thin`:
+
+```sh
 ...
- 68 [profile.release]
- ...
- 71 # currently enabled, may increase build time, but runtime faster, can set to `"thin"`.
- 72 lto = "thin"
- ...
+[profile.release]
+# currently enabled, may increase build time, but runtime faster, can set to `"thin"`.
+lto = "thin"
 ```
-Set `RUSTFLAGS` on build
+
+Set `RUSTFLAGS` on build, as follows:
+
 ```bash
 RUSTFLAGS="-Clink-arg=-Wl,--allow-multiple-definition" cargo +stable build --release 
 ```
+
+Once the build completes, you should find the generated binary `lightning-node` under the directory `~/fleek-network/lightning/target/release/lightning-node`.
+
+As an example, execute:
+
+```sh
+~/fleek-network/lightning/target/release/lightning-node help
+```
+
+To find the help output:
+
+```sh
+Usage: lightning-node [OPTIONS] <COMMAND>
+
+Commands:
+  run           Start the node
+  keys          Handle keys
+  print-config  Print the loaded configuration
+  help          Print this message or the help of the given subcommand(s)
+
+Options:
+  -c, --config <CONFIG>      Path to the toml configuration file [default: ~/.lightning/config.toml]
+      --with-mock-consensus  Determines that we should be using the mock consensus backend
+  -v...                      Increases the level of verbosity (the max level is -vvv)
+      --log-location         Print code location on console logs
+  -h, --help                 Print help
+  -V, --version              Print version
