 ## Installation
 
-For now, the only supported way to install the tool is to use `cargo`. For this you need to have `rust` installed. You can install `rust` by following the instructions on the [official website](https://www.rust-lang.org/tools/install).
+You can install `cc-downloader`` via our pre-built binaries, or by compiling it from source.
 
-After installing `rust`, ``cc-downloader`` can be installed with the following command:
+### Pre-built binaries
+
+You can find our pre-built binaries on our [GitHub releases page](https://github.com/commoncrawl/cc-downloader/releases). They are available for `Linux`, `macOS`, and `Windows`, in `x86_64` and `aarch64` architectures (Windows is only supported in `x86_64`). In order to use them please select and download the correct binary for your system.
+
+```bash
+wget https://github.com/commoncrawl/cc-downloader/releases/download/[VERSION]/cc-downloader-[VERSION]-[ARCH]-[OS].[COMPRESSION-FORMAT]
+```
+
+After downloading it, please verify the checksum of the binary. You can find the checksum file in the same location as the binary. The checksum is generated using `sha512sum`. You can verify it by running the following command:
+
+```bash
+wget https://github.com/commoncrawl/cc-downloader/releases/download/[VERSION]/cc-downloader-[VERSION]-[ARCH]-[OS].sha512
+sha512sum -c cc-downloader-[VERSION]-[ARCH]-[OS].sha512
+```
+
+If the checksum is valid, which will be indicated by and `OK` message, you can proceed to extract the binary. For `tar.gz` files you can use the following command:
+
+```bash
+tar -xzf cc-downloader-[VERSION]-[ARCH]-[OS].tar.gz
+```
+
+For `zip` files you can use the following command:
+
+```bash
+unzip cc-downloader-[VERSION]-[ARCH]-[OS].zip
+```
+
+This will extract the binary, the licenses and the readme file **in the current folder**. After extracting the binary, you can run it by executing the following command:
+
+```bash
+./cc-downloader
+```
+
+If you want to use the binary from anywhere, you can move it to a folder in your `PATH`. For more information on how to do this, please refer to the documentation of your operating system. For example, on `Linux` and `macOS` you can move it to `~/.bin`:
+
+```bash
+mv cc-downloader ~/.bin
+```
+
+And then add the following line to your `~/.bashrc` or `~/.zshrc` file:
+
+```bash
+export PATH=$PATH:~/.bin
+```
+
+then run the following command to apply the changes:
+
+```bash
+source ~/.bashrc
+```
+
+or 
+
+```bash
+source ~/.zshrc
+```
+
+Then, you can run the binary from anywhere. If you want to update the binary, you can repeat the process and download the new version. Make sure to replace the binary that is stored in the folder that you added to your `PATH`. If you want to remove the binary, you can simply delete from this folder.
+
+### Compiling from source
+
+For this you need to have `rust` installed. You can install `rust` by following the instructions on the [official website](https://www.rust-lang.org/tools/install).
+
+Or by running the following command:
+
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+
+Even if you have `rust` a system-wide installation, we recommend the linked installation method. A system-wide installation and a user installation can co-exist without any problems.
+
+When compiling from source, please make sure you have the latest version of `rust` installed by running the following command:
+
+```bash
+rustup update
+```
+
+Now you can install the `cc-downloader` tool by running the following command:
 
 ```bash
 cargo install cc-downloader
