-------------------------
+## Preparation
+1. Install macOS Command Line Tools (if not already installed):
+   ```bash
+   xcode-select --install
+   ```
+   When the popup appears, click `Install`.
+
+
+2. Install Homebrew (if not already installed):
+   ```bash
+   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+   ```
+
+
+## Dependencies
+Install the required dependencies using Homebrew:
+```bash
+brew install automake berkeley-db4 libtool boost miniupnpc openssl pkg-config protobuf python qt libevent qrencode python-setuptools m4
+```
+
+In case you want to build the disk image with `make deploy` (.dmg / optional), you need RSVG:
+```bash
+brew install librsvg
+```
+
+### Ensure `m4` is Found
+After installing `m4`, it is important to note that `m4` is a `keg-only` formula in Homebrew. This means it is not symlinked into `/usr/local` by default. To make sure `m4` is available in your PATH, you'll need to link it manually with the `--force` flag:
+```bash
+brew link m4 --force
+```
+
+You can verify that `m4` is properly linked and available by running:
+```bash
+which m4
+```
+This should output the path to the `m4` binary, typically `/opt/homebrew/bin/m4` on Apple Silicon Macs. If you do not use the `--force` flag, `which m4` will likely output `/usr/bin/m4`, which is the system version and not the one installed via Homebrew.
+
+### Troubleshooting `m4` Issues
+If `m4` is not found even after installation and linking with `--force`, you may need to install Xcode to ensure that `m4` is recognized:
+
+1. Install Xcode from the Mac App Store.
+2. Once installed, open Xcode at least once to complete the setup.
+
+#### Berkeley DB
 It is recommended to use Berkeley DB 4.8. If you have to build it yourself, you can use [the installation script included in contrib/](https://github.com/bitcoin/bitcoin/blob/master/contrib/install_db4.sh) like so:
-    ./contrib/install_db4.sh .
-
+```bash
+./contrib/install_db4.sh 
+```
 from the root of the repository.
 
-Note: You only need Berkeley DB if the wallet is enabled (see Disable-wallet mode).
-
-
-Build Firo Core
-------------------------
-1.  Build Firo-core:
-
-    Configure and build the headless Firo binaries as well as the GUI (if Qt is found).
-
-    In case you want to build the disk image with `make deploy` (.dmg / optional), by passing `--with-gui` to configure.
-
-    You can disable the GUI build by passing `--without-gui` to configure.
-
-        ./autogen.sh
-        ./configure
-        make
-
-2.  It is recommended to build and run the unit tests:
-
-       ` make check`
+*Note*: You only need Berkeley DB if the wallet is enabled (see Disable-wallet mode).
+
+## Build Instructions
+
+#### Download the Source
+Before building, download the Firo source code:
+```bash
+git clone https://github.com/firoorg/firo
+cd firo
+```
+
+#### Build Firo Core
+1. **Prepare the build environment**:
+   ```bash
+   cd depends
+   make
+   cd ..
+   ```
+
+2. **Configure and build Firo-core**:
+   ```bash
+   ./autogen.sh
+   ./configure --prefix=`pwd`/depends/`depends/config.guess`
+   make
+   ```
+
+3. (optional) **It is recommended to build and run the unit tests**:
+   ```bash
+   ./configure --prefix=`pwd`/depends/`depends/config.guess` --enable-tests
+   make check
+   ```
