+# FOR ARM64 ONLY
+---
+## Onlyoffice-Documentserver with `arm64` support
+### This runs a modified version of the official deb package with the help of `qemu` and `binfmt`
+### To see how I did it, look [at this comment](https://github.com/ONLYOFFICE/DocumentServer/issues/152#issuecomment-1061902836) - I used this method and put it in `Dockerfile` so you don't have to mess aroud with your system in any weird ways (like in the mentioned comment)
+
+## Installation
+#### 1. Clone the repository (for example to your home directory `cd /home/$USER/`) 
+
+   `git clone https://github.com/jiriks74/Docker-DocumentServer-Arm64.git && cd Docker-DocumentServer-Arm64`
+
+#### 2. Build the docker image 
+   `docker-compose build` 
+   - This will take a long time. The things that takte the longes are `dpkg-deb: building package 'onlyoffice-documentserver' in 'onlyoffice-documentserver-modified.deb'` and `Generating presentation themes...` - Both of them take like 20 minutes, it's not stuck, it's just slow
+
+#### 3. Create and start the container
+   `docker-compose up -d --build` 
+   - This will start the server. It is set to be automatically started/restarted so as long you have docker running on startup this will start automatically
+
+## Updating
+#### 1. Stop and delete the old container
+
+   `docker-compose down`
+   
+#### 2. (optional) Clear the docker cache 
+####    - ! This will remove all unused cache images ! (good for saving space, bad if you develop with and need cache, but you understand it at that point)
+
+   `docker rmi $(docker images -f "dangling=true" -q)`
+
+#### 4. Rebuild the image without cache
+
+   `docker-compose build --no-cache`
+   
+#### 3. Create and start the new container
+
+   `docker-compose up -d`
