-# Contributing
-This document is a work-in-progress and will be expanded as time goes on. If you have any questions feel free to open a issue on GitHub.
+# Contributing to the source code
+We welcome contributions to AliasVault. Please read the guidelines on the official AliasVault docs website on how to get your local development environment setup and the general contribution guidelines:
 
-Note: all instructions below are based on MacOS. If you are using a different operating system, you may need to adjust the commands accordingly.
+https://docs.aliasvault.net/misc/dev/contributing.html
 
-## Getting Started
-In order to contribute to this project follow these instructions to setup your local environment:
+> Tip: if the URL above is not available, the raw doc pages can also be found in the `docs` folder in this repository.
 
-### 1. Clone the repository
+## Contributing to the documentation
+The docs are built using Jekyll and automatically deploy to GitHub Pages via GitHub Actions. You can build the docs locally by running `docker compose up` in in the `./docs` folder.
 
-```bash
-git clone https://github.com/lanedirt/AliasVault.git
-cd AliasVault
-```
-
-### 2. Copy pre-commit hook script to .git/hooks directory
-**Important**: All commits in this repo are required to contain a reference to a GitHub issue in the format of "your commit message (#123)" where "123" references the GitHub issue number.
-
-The pre-commit hook script below will check the commit message before allowing the commit to proceed. If the commit message is invalid, the commit will be aborted.
-
-```bash
-# Copy the commit-msg hook script to the .git/hooks directory
-cp .github/hooks/commit-msg .git/hooks/commit-msg
-
-# Make the script executable
-chmod +x .git/hooks/commit-msg
-```
-
-### 3. Install the latest version of .NET SDK 8
-
-```bash
-# Install .NET SDK 8
-
-# On MacOS via brew:
-brew install --cask dotnet-sdk
-
-# On Windows via winget
-winget install Microsoft.DotNet.SDK.8
-```
-
-### 4. Install dotnet CLI EF Tools
-
-```bash
-# Install dotnet EF tools globally
-dotnet tool install --global dotnet-ef
-# Include dotnet tools in your PATH
-nano ~/.zshrc
-# Add the following line to your .zshrc file
-export PATH="$PATH:$HOME/.dotnet/tools"
-# Start a new terminal and test that this command works:
-dotnet ef
-```
-
-### 5. Run Tailwind CSS compiler while changing HTML files to update compiled CSS
-
-```bash
-npm run build:css
-```
-
-### 6. Install Playwright in order to locally run NUnit E2E (end-to-end) tests
-
-```bash
-# First install PowerShell for Mac (if you don't have it already)
-brew install powershell/tap/powershell
-# Install Playwright
-dotnet tool install --global Microsoft.Playwright.CLI
-# Run Playwright install script to download local browsers
-# Note: make sure the E2E test project has been built at least once so the bin dir exists.
-pwsh src/Tests/AliasVault.E2ETests/bin/Debug/net8.0/playwright.ps1 install
-```
-
-### 7. Create AliasVault.Client appsettings.Development.json
-The WASM client app supports a development specific appsettings.json file. This appsettings file is optional but can override various options to make debugging easier.
+The docs site is based on the open-source template called Just The Docs. Find more information about how this template works in the [official docs](https://just-the-docs.github.io/just-the-docs/).
 
 
-1. Copy `wwwroot/appsettings.json` to `wwwroot/appsettings.Development.json`
-
-Here is an example file with the various options explained:
-
-```
-{
-    "ApiUrl": "http://localhost:5092",
-    "PrivateEmailDomains": ["example.tld"],
-    "SupportEmail": "support@example.tld",
-    "UseDebugEncryptionKey": "true",
-    "CryptographyOverrideType" : "Argon2Id",
-    "CryptographyOverrideSettings" : "{\"DegreeOfParallelism\":1,\"MemorySize\":1024,\"Iterations\":1}"
-}
-```
-
-- UseDebugEncryptionKey
-    - This setting will use a static encryption key so that if you login as a user you can refresh the page without needing to unlock the database again. This speeds up development when changing things in the WebApp WASM project. Note: the project needs to be run in "Development" mode for this setting to be used.
-
-- CryptographyOverrideType
-    - This setting allows overriding the default encryption type (Argon2id) with a different encryption type. This is useful for testing different encryption types without having to change code.
-
-- CryptographyOverrideSettings
-    - This setting allows overriding the default encryption settings (Argon2id) with different settings. This is useful for testing different encryption settings without having to change code. The default Argon2id settings
-    are defined in the project as `Utilities/Cryptography/Cryptography.Client/Defaults.cs`. These default settings
-    are focused on security but NOT performance. Normally for key derivation purposes the slower/heavier the algorithm
-    the better protection against attackers. For production builds this is what we want, however in case of automated testing or debugging extra performance can be gained by tweaking (lowering) these settings.
+To make changes to the AliasVault documentation please make a PR that directly edits the `docs` markdown files in this repository.

-## 4. Troubleshooting
+## 4. Configure Account Registration
+
+By default, AliasVault is configured to allow public registration of new accounts. This means that anyone can create a new account on your server.
+
+If you want to disable public registration, you can do so by running the install script with the `configure-registration` option and then choosing option 2.
+
+```bash
+./install.sh configure-registration
+```
+
+> Note: disabling public registration means the ability to create new accounts in the AliasVault client is disabled for everyone, including administrators. Accounts cannot be created outside of the client because of the end-to-end encryption employed by AliasVault. So make sure you have created your own account(s) before disabling public registration.
+

+
+## 5. Troubleshooting
 
 ### Resetting the admin password
 If you have lost your admin password, you can reset it by running the install script with the `reset-password` option. This will generate a new random password and update the .env file with it. After that it will restart the AliasVault containers to apply the changes.

+# Upgrading to v0.10.0
+{: .no_toc }
+
+This guide covers the upgrade process from version < v0.10.0 to v0.10.0 or newer, which includes a one-time database migration from SQLite to PostgreSQL.
+
+The v0.10.0 release introduces a new database backend, PostgreSQL, which replaces SQLite. This change is required because SQLite is not suitable for environments with concurrent writes that AliasVault requires.
+
+A built-in database migration tool is included in the installer script to help you migrate your data from SQLite to PostgreSQL.
+
+## Update Steps
+
+1. First, backup your existing SQLite database:
+```bash
+cp database/AliasServerDb.sqlite database/AliasServerDb.sqlite.backup
+```
+2. Update AliasVault to the latest version:
+```bash
+./install.sh update
+```
+3. Run the database migration tool:
+```bash
+./install.sh migrate-db
+```
+4. After the migration has completed successfully, restart all AliasVault containers:
+```bash
+./install.sh restart
+```
+
+5. Test the upgrade by logging in to the admin panel and checking that your data is intact.
+
+If you encounter any issues during the upgrade, please create an issue on the [GitHub repository](https://github.com/lanedirt/AliasVault/issues) or contact via Discord.

+# Contributing
+This document is a work-in-progress and will be expanded as time goes on. If you have any questions feel free to open a issue on GitHub.
+
+Note: all instructions below are based on MacOS. If you are using a different operating system, you may need to adjust the commands accordingly.
+
+## Getting Started
+In order to contribute to this project follow these instructions to setup your local environment:
+
+### 1. Clone the repository
+```bash
+git clone https://github.com/lanedirt/AliasVault.git
+cd AliasVault
+```
+
+### 2. Copy pre-commit hook script to .git/hooks directory
+{: .note }
+All commits in this repo are required to contain a reference to a GitHub issue in the format of "your commit message (#123)" where "123" references the GitHub issue number.
+
+The pre-commit hook script below will check the commit message before allowing the commit to proceed. If the commit message is invalid, the commit will be aborted.
+
+```bash
+# Copy the commit-msg hook script to the .git/hooks directory
+cp .github/hooks/commit-msg .git/hooks/commit-msg
+
+# Make the script executable
+chmod +x .git/hooks/commit-msg
+```
+
+### 3. Install the latest version of .NET SDK 9
+```bash
+# Install .NET SDK 9
+
+# On MacOS via brew:
+brew install --cask dotnet-sdk
+
+# On Windows via winget
+winget install Microsoft.DotNet.SDK.9
+```
+
+### 4. Install dotnet CLI EF Tools
+```bash
+# Install dotnet EF tools globally
+dotnet tool install --global dotnet-ef
+# Include dotnet tools in your PATH
+nano ~/.zshrc
+# Add the following line to your .zshrc file
+export PATH="$PATH:$HOME/.dotnet/tools"
+# Start a new terminal and test that this command works:
+dotnet ef
+```
+
+### 5. Install dev database
+AliasVault uses PostgreSQL as its database. In order to run the project locally from Visual Studio / Rider you will need to install the dev database. You can do this by running the following command. This will start a separate PostgreSQL instance on port 5433 accessible via the `localhost:5433` address.
+
+```bash
+./install.sh configure-dev-db
+```
+
+After the database is running you can start the project from Visual Studio / Rider in run or debug mode and it should be able to connect to the dev database.
+
+### 6. Run Tailwind CSS compiler when changing HTML files to update compiled CSS
+```bash
+# For Admin project (in the admin project directory)
+npm run build:admin-css
+# For Client project (in the client project directory)
+npm run build:client-css
+```
+
+### 7. Install Playwright in order to locally run NUnit E2E (end-to-end) tests
+```bash
+# First install PowerShell for Mac (if you don't have it already)
+brew install powershell/tap/powershell
+# Install Playwright
+dotnet tool install --global Microsoft.Playwright.CLI
+# Run Playwright install script to download local browsers
+# Note: make sure the E2E test project has been built at least once so the bin dir exists.
+pwsh src/Tests/AliasVault.E2ETests/bin/Debug/net9.0/playwright.ps1 install
+```
+
+### 8. Create AliasVault.Client appsettings.Development.json
+The WASM client app supports a development specific appsettings.json file. This appsettings file is optional but can override various options to make debugging easier.
+
+1. Copy `wwwroot/appsettings.json` to `wwwroot/appsettings.Development.json`
+
+Here is an example file with the various options explained:
+
+```json
+{
+    "ApiUrl": "http://localhost:5092",
+    "PrivateEmailDomains": ["example.tld"],
+    "SupportEmail": "support@example.tld",
+    "UseDebugEncryptionKey": "true",
+    "CryptographyOverrideType" : "Argon2Id",
+    "CryptographyOverrideSettings" : "{\"DegreeOfParallelism\":1,\"MemorySize\":1024,\"Iterations\":1}"
+}
+```
+
+- **UseDebugEncryptionKey**
+  - This setting will use a static encryption key so that if you login as a user you can refresh the page without needing to unlock the database again. This speeds up development when changing things in the WebApp WASM project. Note: the project needs to be run in "Development" mode for this setting to be used.
+
+- **CryptographyOverrideType**
+  - This setting allows overriding the default encryption type (Argon2id) with a different encryption type. This is useful for testing different encryption types without having to change code.
+
+- **CryptographyOverrideSettings**
+  - This setting allows overriding the default encryption settings (Argon2id) with different settings. This is useful for testing different encryption settings without having to change code. The default Argon2id settings are defined in the project as `Utilities/Cryptography/Cryptography.Client/Defaults.cs`. These default settings are focused on security but NOT performance. Normally for key derivation purposes the slower/heavier the algorithm the better protection against attackers. For production builds this is what we want, however in case of automated testing or debugging extra performance can be gained by tweaking (lowering) these settings.
