## 🚀 Download Setup
It is recommended to give priority to installing through the application market on the desktop and mobile, so that you can upgrade the version with one click in the future.
### App Market
Mobile:
* [App Store](https://apps.apple.com/us/app/siyuan/id1583226508)
* [Google Play](https://play.google.com/store/apps/details?id=org.b3log.siyuan)
* [F-Droid](https://f-droid.org/packages/org.b3log.siyuan)
Desktop:
* [Microsoft Store](https://apps.microsoft.com/detail/9p7hpmxp73k4)
### Installation Package
* [B3log](https://b3log.org/siyuan/en/download.html)
* [GitHub](https://github.com/siyuan-note/siyuan/releases)
### Docker Hosting
Docker Deployment
#### Overview
The easiest way to serve SiYuan on a server is to deploy it through Docker.
* Image name `b3log/siyuan`
* [Image URL](https://hub.docker.com/r/b3log/siyuan)
#### File structure
The overall program is located under `/opt/siyuan/`, which is basically the structure under the resources folder of the Electron installation package:
* appearance: icon, theme, languages
* guide: user guide document
* stage: interface and static resources
* kernel: kernel program
#### Entrypoint
The entry point is set when building the Docker image: `ENTRYPOINT ["/opt/siyuan/kernel" ]`, use `docker run b3log/siyuan` with parameters to start:
* `--workspace`: Specifies the workspace folder path, mounted to the container via `-v` on the host
* `--accessAuthCode`: Specifies the access authorization code
More parameters can refer to `--help`. The following is an example of a startup command:
```
docker run -d -v workspace_dir_host:workspace_dir_container -p 6806:6806 b3log/siyuan --workspace=workspace_dir_container --accessAuthCode=xxx
```
* `workspace_dir_host`: The workspace folder path on the host
* `workspace_dir_container`: The path of the workspace folder in the container, which is the same as specified in `--workspace`
* `accessAuthCode`: Access authorization code, please **be sure to modify**, otherwise anyone can read and write your data
To simplify, it is recommended to configure the workspace folder path to be consistent on the host and container, such as: `workspace_dir_host` and `workspace_dir_container` are configured as `/siyuan/workspace`, the corresponding startup commands is:
```
docker run -d -v /siyuan/workspace:/siyuan/workspace -p 6806:6806 -u 1000:1000 b3log/siyuan --workspace=/siyuan/workspace/ --accessAuthCode=xxx
```
Alternatively, see below for an example Docker Compose file:
```
version: "3.9"
services:
main:
image: b3log/siyuan
command: ['--workspace=/siyuan/workspace/', '--accessAuthCode=${AuthCode}']
user: '1000:1000'
ports:
- 6806:6806
volumes:
- /siyuan/workspace:/siyuan/workspace
restart: unless-stopped
environment:
# A list of time zone identifiers can be found at https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
- TZ=${TimeZone}
```
#### User permissions
In the image, the normal user `siyuan` (uid 1000/gid 1000) created by default is used to start the kernel process. Therefore, when the host creates a workspace folder, please pay attention to setting the user group of the folder: `chown -R 1000:1000 /siyuan/workspace`. The parameter `-u 1000:1000` is required when starting the container.
#### Hidden port
Use NGINX reverse proxy to hide port 6806, please note:
* Configure WebSocket reverse proxy `/ws`
#### Note
* Be sure to confirm the correctness of the mounted volume, otherwise the data will be lost after the container is deleted
* Do not use URL rewriting for redirection, otherwise there may be problems with authentication, it is recommended to configure a reverse proxy
#### Limitations
* Does not support desktop and mobile application connections, only supports use on browsers
* Export to PDF, HTML and Word formats is not supported
* Import Markdown file is not supported
### Unraid Hosting
Unraid Deployment
Note: First run `chown -R 1000:1000 /mnt/user/appdata/siyuan` in the terminal
Template reference:
```
Web UI: 6806
Container Port: 6806
Container Path: /home/siyuan
Host path: /mnt/user/appdata/siyuan
PUID: 1000
PGID: 1000
Publish parameters: --accessAuthCode=******(Access authorization code)
```

## ❓ FAQ
### How does SiYuan store data?
The data is saved in the workspace folder, in the workspace data folder:
* `assets` is used to save all inserted assets
* `emojis` is used to save emoji images
* `snippets` is used to save code snippets
* `storage` is used to save query conditions, layouts and flashcards, etc.
* `templates` is used to save template snippets
* `widgets` is used to save widgets
* `plugins` is used to save plugins
* `public` is used to save public data
* The rest of the folders are the notebook folders created by the user, files with the suffix of `.sy` in the notebook folder are used to save the document data, and the data format is JSON
### Does it support data synchronization through a third-party sync disk?
Data synchronization through third-party synchronization disks is not supported, otherwise data may be corrupted.
Although it does not support third-party sync disks, it supports connect with third-party cloud storage (Member's privileges).
In addition, you can also consider manually exporting and importing data to achieve data synchronization:
* Desktop: Settings - Export - Export Data / Import Data
* Mobile: Right column - About - Export Data / Import Data
### Is SiYuan open source?

* [User Interface and Kernel](https://github.com/siyuan-note/siyuan)
* [Android](https://github.com/siyuan-note/siyuan-android)
* [iOS](https://github.com/siyuan-note/siyuan-ios)
* [Chrome Clipping Extension](https://github.com/siyuan-note/siyuan-chrome)
For more details, please refer to [Development Guide](https://github.com/siyuan-note/siyuan/blob/master/.github/CONTRIBUTING.md).
### How to upgrade to a new version?
* If installed via app store, please update via app store
* If it is installed through the installation package on the desktop, you can open the option of Settings - About - Automatically download update installation package, so that SiYuan will automatically download The latest version of the installation package and prompts to install
* If it is installed by manual installation package, please download the installation package again to install
You can Check update in Settings - About - Current Version, or pay attention to [Official Download](https://b3log.org/siyuan/en/download.html) or [GitHub Releases](https://github.com/siyuan-note/siyuan/releases) to get the new version.
### What if some blocks (such as paragraph blocks in list items) cannot find the block icon?
The first sub-block under the list item is the block icon omitted. You can move the cursor into this block and trigger its block menu with Ctrl+/ .
### What should I do if the data repo key is lost?
* If the data repo key is correctly initialized on multiple devices before, the key is the same on all devices and can be set in Settings - About - Data repo key - Copy key string retrieve
* If it has not been configured correctly before (for example, the keys on multiple devices are inconsistent) or all devices are unavailable and the key string cannot be obtained, you can reset the key by following the steps below:
1. Manually back up the data, you can use Export Data or directly copy the workspace/data/ folder on the file system
2. Settings - About - Data rep key - Reset data repo
3. Reinitialize the data repo key. After initializing the key on one device, other devices import the key
4. The cloud uses the new synchronization directory, the old synchronization directory is no longer available and can be deleted
5. The existing cloud snapshots are no longer available and can be deleted
### Do I need to pay for it?
Most features are free, even for commercial use.
Member's privileges can only be used after payment, please refer to [Pricing](https://b3log.org/siyuan/en/pricing.html).
