 ## Deploy with Docker in seconds
 
-### Docker Run
-
-```docker
-docker run -d --name memos -p 5230:5230 -v ~/.memos/:/var/opt/memos neosmemo/memos:latest
+```bash
+docker run -d --name memos -p 5230:5230 -v ~/.memos/:/var/opt/memos ghcr.io/usememos/memos:latest
 ```
 
-Memos should be running at [http://localhost:5230](http://localhost:5230). If the `~/.memos/` does not have a `memos_prod.db` file, then memos will auto generate it.
+> The `~/.memos/` directory will be used as the data directory on your local machine, while `/var/opt/memos` is the directory of the volume in Docker and should not be modified.
 
-### Docker Compose
+Learn more about [other installation methods](https://usememos.com/docs#installation).
 
-Example Compose YAML file: [`docker-compose.yaml`](./docker-compose.yaml).

+# Guide to Access Memos API with OpenID
+
+Memos API supports using OpenID as the user identifier to access the API.
+
+## What is OpenID
+
+OpenID is a unique identifier assigned by Memos system to each user.
+
+When a user registers or logs in via third-party OAuth through Memos system, the OpenID will be generated automatically.
+
+## How to Get User's OpenID
+
+You can get a user's OpenID through:
+
+- User checks the personal profile page in Memos system
+- Calling Memos API to get user details
+- Retrieving from login API response after successful login
+
+Example:
+
+```
+// GET /api/v1/user/me
+
+{
+  "id": 123,
+  "username": "john",
+  "openId": "8613E04B4FA6603883F05A5E0A5E2517",
+  ...
+}
+```
+
+## How to Use OpenID to Access API
+
+You can access the API on behalf of the user by appending `?openId=xxx` parameter to the API URL.
+
+For example:
+
+```
+curl 'https://demo.usememos.com/api/v1/memo?openId=8613E04B4FA6603883F05A5E0A5E2517' -H 'Content-Type: application/json' --data-raw '{"content":"Hello world!"}'
+```
+
+The above request will create a Memo under the user with OpenID `8613E04B4FA6603883F05A5E0A5E2517`.
+
+OpenID can be used in any API that requires user identity.

+# A Beginner's Guide to Deploying Memos on Render.com
+
+written by [AJ](https://memos.ajstephens.website/) (also a noob)
+
+<img height="64px" src="https://usememos.com/logo-full.png" alt="✍️ memos" />
+
+[Live Demo](https://demo.usememos.com) • [Official Website](https://usememos.com) • [Source Code](https://github.com/usememos/memos)
+
+## Who is this guide for?
+
+Someone who...
+
+- doesn't have much experience with self hosting
+- has a minimal understanding of docker
+
+Someone who wants...
+
+- to use memos
+- to support the memos project
+- a cost effective and simple way to host it on the cloud with reliability and persistance
+- to share memos with friends
+
+## Requirements
+
+- Can follow instructions
+- Have 7ish USD a month on a debit/credit card
+
+## Guide
+
+Create an account at [Render](https://dashboard.render.com/register)
+![ss1](https://i.imgur.com/l3K7aqC.png)
+
+1. Go to your dashboard
+
+[https://dashboard.render.com/](https://dashboard.render.com/)
+
+2. Select New Web Service
+
+   ![ss2](https://i.imgur.com/IIDdK2y.png)
+
+3. Scroll down to "Public Git repository"
+
+4. Paste in the link for the public git repository for memos (https://github.com/usememos/memos) and press continue
+
+   ![ss3](https://i.imgur.com/OXoCWoJ.png)
+
+5. Render will pre-fill most of the fields but you will need to create a unique name for your web service
+
+6. Adjust region if you want to
+
+7. Don't touch the "branch", "root directory", and "environment" fields
+
+   ![ss4](https://i.imgur.com/v7Sw3fp.png)
+
+8. Click "enter your payment information" and do so
+
+   ![ss5](https://i.imgur.com/paKcQFl.png)
+
+   ![ss6](https://i.imgur.com/JdcO1HC.png)
+
+9. Select the starter plan ($7 a month - a requirement for persistant data - render's free instances spin down when inactive and lose all data)
+
+10. Click "Create Web Service"
+
+![ss7](https://i.imgur.com/MHe45J4.png)
+
+11. Wait patiently while the _magic_ happens 🤷‍♂️
+
+![ss8](https://i.imgur.com/h1PXHHJ.png)
+
+12. After some time (~ 6 min for me) the build will finish and you will see the web service is live
+
+![ss9](https://i.imgur.com/msapkRw.png)
+
+13. Now it's time to add the disk so your data won't dissappear when the webservice redeploys (redeploys happen automatically when the public repo is updated)
+
+14. Select the "Disks" tab on the left menu and then click "Add Disk"
+
+![ss10](https://i.imgur.com/rGeI0bv.png)
+
+15. Name your disk (can be whatever)
+
+16. Set the "Mount Path" to `/var/opt/memos`
+
+17. Set the disk size (default is 10GB but 1GB is plenty and can be increased at any time)
+
+18. Click "Save"
+
+    ![ss11](https://i.imgur.com/Jbg7O6q.png)
+
+19. Wait...again...while the webservice redeploys with the persistant disk
+
+    ![ss12](https://i.imgur.com/pTzpE34.png)
+
+20. aaaand....we're back online!
+
+    ![ss13](https://i.imgur.com/qdsFfSa.png)
+
+21. Time to test! We're going to make sure everything is working correctly.
+
+22. Click the link in the top left, it should look like `https://the-name-you-chose.onrender.com` - this is your self hosted memos link!
+
+    ![ss14](https://i.imgur.com/cgzFSIn.png)
+
+23. Create a Username and Password (remember these) then click "Sign up as Host"
+
+    ![ss15](https://i.imgur.com/kuRStAj.png)
+
+24. Create a test memo then click save
+
+    ![ss16](https://i.imgur.com/Eh2AB44.png)
+
+25. Sign out of your self-hosted memos
+
+    ![ss17](https://i.imgur.com/0mMb88G.png)
+
+26. Return to your Render dashboard, click the "Manual Deploy" dropdown button and click "Deploy latest commit" and wait until the webservice is live again (This is to test that your data is persistant)
+
+    ![ss18](https://i.imgur.com/w1N7VTb.png)
+
+27. Once the webservice is live go back to your self-hosted memos page and sign in! (If your memos screen looks different then something went wrong)
+
+28. Once you're logged in, verify your test memo is still there after the redeploy
+
+    ![ss19](https://i.imgur.com/dTcEQZS.png)

+# Development
+
+Memos is built with a curated tech stack. It is optimized for developer experience and is very easy to start working on the code:
+
+1. It has no external dependency.
+2. It requires zero config.
+3. 1 command to start backend and 1 command to start frontend, both with live reload support.
+
+## Tech Stack
+
+|                 Frontend                 |              Backend              |
+| ---------------------------------------- | --------------------------------- |
+| [React](https://react.dev/)              | [Go](https://go.dev/)             |
+| [Tailwind CSS](https://tailwindcss.com/) | [SQLite](https://www.sqlite.org/) |

+
+## Prerequisites
+
+- [Go](https://golang.org/doc/install)
+- [Air](https://github.com/cosmtrek/air#installation) for backend live reload
+- [Node.js](https://nodejs.org/)
+- [pnpm](https://pnpm.io/installation)
+
+## Steps
+
+(Using PowerShell)
+
+1. pull source code
+
+   ```powershell
+   git clone https://github.com/usememos/memos
+   # or
+   gh repo clone usememos/memos
+   ```
+
+2. cd into the project root directory
+
+   ```powershell
+   cd memos
+   ```
+
+3. start backend using air (with live reload)
+
+   ```powershell
+   air -c .\scripts\.air-windows.toml
+   ```
+
+4. start frontend dev server
+
+   ```powershell
+   cd web; pnpm i; pnpm dev
+   ```
+
+Memos should now be running at [http://localhost:3001](http://localhost:3001) and changing either frontend or backend code would trigger live reload.
+
+## Building
+
+Frontend must be built before backend. The built frontend must be placed in the backend ./server/dist directory. Otherwise, you will get a "No frontend embeded" error.
+
+### Frontend
+
+```powershell
+Move-Item "./server/dist" "./server/dist.bak"
+cd web; pnpm i --frozen-lockfile; pnpm build; cd ..;
+Move-Item "./web/dist" "./server/" -Force
+```
+
+### Backend
+
+```powershell
+go build -o ./build/memos.exe ./main.go
+```
+
+## ❕ Notes
+
+- Start development servers easier by running the provided `start.ps1` script.
+This will start both backend and frontend in detached PowerShell windows:
+
+   ```powershell
+   .\scripts\start.ps1
+   ```
+
+- Produce a local build easier using the provided `build.ps1` script to build both frontend and backend:
+
+   ```powershell
+   .\scripts\build.ps1
+   ```
+
+   This will produce a memos.exe file in the ./build directory.

+# Setup
+
+After deploying and running Memos in `prod` mode, you should create "host" user. There are two ways to do this:
+
+1. Navigate to the Memos application URL, such as `http://localhost:5230`, and follow the prompts to create a username and password for the "host" user.
+2. Use the command `memos setup --host-username=$USERNAME --host-password=$PASSWORD --mode=prod` to set up the host user. This method may be more convenient for deploying through Ansible or other provisioning softwares.

+# Installing memos as a service on Windows
+
+While memos first-class support is for Docker, you may also install memos as a Windows service. It will run under SYSTEM account and start automatically at system boot.
+
+❗ All service management methods requires admin privileges. Use [gsudo](https://gerardog.github.io/gsudo/docs/install), or open a new PowerShell terminal as admin:
+
+```powershell
+Start-Process powershell -Verb RunAs
+```
+
+## Choose one of the following methods
+
+### 1. Using [NSSM](https://nssm.cc/download)
+
+NSSM is a lightweight service wrapper.
+
+You may put `nssm.exe` in the same directory as `memos.exe`, or add its directory to your system PATH. Prefer the latest 64-bit version of `nssm.exe`.
+
+```powershell
+# Install memos as a service
+nssm install memos "C:\path\to\memos.exe" --mode prod --port 5230
+
+# Delay auto start
+nssm set memos DisplayName "memos service"
+
+# Configure extra service parameters
+nssm set memos Description "A lightweight, self-hosted memo hub. https://usememos.com/" 
+
+# Delay auto start
+nssm set memos Start SERVICE_DELAYED_AUTO_START
+
+# Edit service using NSSM GUI
+nssm edit memos
+
+# Start the service
+nssm start memos
+
+# Remove the service, if ever needed
+nssm remove memos confirm
+```
+
+### 2. Using [WinSW](https://github.com/winsw/winsw)
+
+Find the latest release tag and download the asset `WinSW-net46x.exe`. Then, put it in the same directory as `memos.exe` and rename it to `memos-service.exe`.
+
+Now, in the same directory, create the service configuration file `memos-service.xml`:
+
+```xml
+<service>
+    <id>memos</id>
+    <name>memos service</name>
+    <description>A lightweight, self-hosted memo hub. https://usememos.com/</description>
+    <onfailure action="restart" delay="10 sec"/>
+    <executable>%BASE%\memos.exe</executable>
+    <arguments>--mode prod --port 5230</arguments>
+    <delayedAutoStart>true</delayedAutoStart>
+    <log mode="none" />   
+</service>
+```
+
+Then, install the service:
+
+```powershell
+# Install the service
+.\memos-service.exe install
+
+# Start the service
+.\memos-service.exe start
+
+# Remove the service, if ever needed
+.\memos-service.exe uninstall
+```
+
+### Manage the service
+
+You may use the `net` command to manage the service:
+
+```powershell
+net start memos
+net stop memos
+```
+
+Also, by using one of the provided methods, the service will appear in the Windows Services Manager `services.msc`.
+
+## Notes
+
+- On Windows, memos store its data in the following directory:
+
+    ```powershell
+    $env:ProgramData\memos
+    # Typically, this will resolve to C:\ProgramData\memos
+    ```
+
+    You may specify a custom directory by appending `--data <path>` to the service command line.
+
+- If the service fails to start, you should inspect the Windows Event Viewer `eventvwr.msc`.
+
+- Memos will be accessible at [http://localhost:5230](http://localhost:5230) by default.
