+- Latest stable release [v1.17.1](https://github.com/42wim/matterbridge/releases/latest)
-- Development releases (follows master) can be downloaded [here](https://github.com/42wim/matterbridge/actions) selecting the latest green build and then artifacts.
+- Development releases (follows master) can be downloaded [here](https://dl.bintray.com/42wim/nightly/)
 
-To install or upgrade just download the latest [binary](https://github.com/42wim/matterbridge/releases/latest). On \*nix platforms you may need to make the binary executable - you can do this by running `chmod a+x` on the binary (example: `chmod a+x matterbridge-1.24.1-linux-64bit`). After downloading (and making the binary executable, if necessary), follow the instructions on the [howto](https://github.com/42wim/matterbridge/wiki/How-to-create-your-config) for a step by step walkthrough for creating your configuration.

 ## Building
 
 Most people just want to use binaries, you can find those [here](https://github.com/42wim/matterbridge/releases/latest)
 
 If you really want to build from source, follow these instructions:
-Go 1.18+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed.
+Go 1.12+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed.
 
-Building the binary with **all** the bridges enabled needs about 3GB RAM to compile.
-You can reduce this memory requirement to 0,5GB RAM by adding the `nomsteams` tag if you don't need/use the Microsoft Teams bridge.
 
-Matterbridge can be build without gcc/c-compiler: If you're running on windows first run `set CGO_ENABLED=0` on other platforms you prepend `CGO_ENABLED=0` to the `go build` command. (eg `CGO_ENABLED=0 go install github.com/42wim/matterbridge`)
-
-To install the latest stable run:
-
-```bash
-go install github.com/42wim/matterbridge
 ```
-
+go get github.com/42wim/matterbridge
-To install the latest dev run:
-
-```bash
-go install github.com/42wim/matterbridge@master
-```
-
-To install the latest stable run without msteams or zulip bridge:
-
-```bash
-go install -tags nomsteams,nozulip github.com/42wim/matterbridge
 ```
 
 You should now have matterbridge binary in the ~/go/bin directory:
 
-```bash
-$ ls ~/go/bin/
-matterbridge
 ```
-
-## Building with whatsapp (beta) multidevice support
-
-Because the library we use for Whatsapp multidevice support includes a GPL3 library we can not provide you binaries.
-(as this would require the Matterbridge to change it license to GPL)
-
-Matterbridge can be build without gcc/c-compiler: If you're running on windows first run `set CGO_ENABLED=0` on other platforms you prepend `CGO_ENABLED=0` to the `go build` command. (eg `CGO_ENABLED=0 go install github.com/42wim/matterbridge`)
-
-So this means you have to build it yourself using the instructions below:
-
-```bash
-go install -tags whatsappmulti github.com/42wim/matterbridge@master
-```
-
-If you're low on memory and don't need msteams:
-
-```bash
-go install -tags nomsteams,whatsappmulti github.com/42wim/matterbridge@master
-```
-
-You should now have matterbridge binary in the ~/go/bin directory:
-
-```bash
 $ ls ~/go/bin/
 matterbridge
 ```
