-## Install arc
+## Installation
 
 ### Linux
 
 There are a few ways you can install arc on a Linux amd64 or arm64 system.
 
+#### Ubuntu Apt Repository (recommended)
+I (Ricardo N Feliciano) run an Apt/Debian repository for a lot of my software, which includes Arc.
+The benefit of the Apt repository is that updates are handled by Ubuntu's built-in package manager.
+
+For security reasons, first we install the GPG key for the repository:
+
+```bash
+sudo wget "http://pkg.feliciano.tech/ftech-archive-keyring.gpg" -P /usr/share/keyrings/
+```
+
+Now we add the repository to the system:
+
+```bash
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ftech-archive-keyring.gpg] http://pkg.feliciano.tech/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/felicianotech.list
+```
+
+Finally, we can install Arc:
+
+```bash
+sudo apt update && sudo apt install hubci-arc
+```
+
 #### Debian Package (.deb)

 #### Binary Install
 You can download and run the raw arc binary from the [GitHub Releases page][gh-releases] if you don't want to use any package manager.
 Simply download the tarball for your OS and architecture and extract the binary to somewhere in your `PATH`.
 Here's one way to do this with `curl` and `tar`:
 
 ```bash
-dlURL="https://github.com/hubci/arc/releases/download/v0.1.0/arc-v0.1.0-linux-amd64.tar.gz"
+dlURL="https://github.com/hubci/arc/releases/download/v0.10.0/arc-v0.10.0-linux-amd64.tar.gz"
 curl -sSL $dlURL | sudo tar -xz -C /usr/local/bin arc
