 ## Installation
 
-lego supports both binary installs and install from source.
+### Binaries
 
 To get the binary just download the latest release for your OS/Arch from [the release page](https://github.com/xenolf/lego/releases)
 and put the binary somewhere convenient. lego does not assume anything about the location you run it from.
 
+### From Docker
+
+```bash
+docker run xenolf/lego -h
+```
+
+### From the package manager
+
+- [ArchLinux (AUR)](https://aur.archlinux.org/packages/lego-git):
+
+```bash
+yaourt -S lego-git
+```
+
+### From source
+
 To install from source, just run:
 
 ```bash
 go get -u github.com/xenolf/lego
 ```
 
-To build lego inside a Docker container, just run:
-```bash
-docker build -t lego .
-```
-
-That will build lego from the current source, if you want to build a different
-version, you can checkout the desired branch/tag/commit, and re-running the
-above mentioned command.
-
-If you want to tag the binary with the designated release, you can do so by
-passing the version identifier as a [`--build-arg`](https://docs.docker.com/engine/reference/commandline/build/#set-build-time-variables---build-arg)
-
-```bash
-docker build --build-arg LEGO_VERSION=v1.1.0 -t lego .
-```
-
-Otherwise the release will be tagged with the `dev` version identifier.
