+# Build
+
+The Cloudreve project consists of two main parts: the main backend repository [cloudreve/Cloudreve](https://github.com/cloudreve/Cloudreve), and the frontend repository [cloudreve/frontend](https://github.com/cloudreve/frontend). Before compiling the Cloudreve backend, you need to build the frontend submodules in the `assets` directory and embed them in the backend repository using [statik](https://github.com/rakyll/statik).
+
+## Environment preparation
+
+1. refer to [Getting Started - The Go Programming Language](https://golang.org/doc/install) to install and configure the Go language development environment.
+2. Refer to [Download \| Node.js](https://nodejs.org/download/) to install Node.js;
+3. Refer to [Install \| Yarn](https://classic.yarnpkg.com/docs/install#windows-stable) to install Yarn;
+4. run `go get github.com/rakyll/statik` to install the statik command line tool;
+
+## Start building
+
+### Clone the repository
+
+``bash
+## Clone the repository
+git clone --recurse-submodules https://github.com/cloudreve/Cloudreve.git
+
+# # Check out the version you want to compile
+git checkout 3.x.x
+```
+
+### Build static resources
+
+```bash
+# Access the front-end submodule
+cd assets
+# Install dependencies
+yarn install
+# Start building
+yarn run build
+```
+
+When finished, the static resource files are located in the `assets/build` directory.
+
+You can rename this directory to `statics`, place it in the same level as the main Cloudreve application and restart Cloudreve, which will use the static resource files in this directory instead of the built-in ones.
+
+### Embedding static resources
+
+```bash
+### Return to the project home directory
+cd ../
+
+# Install statik, for embedding static resources
+go get github.com/rakyll/statik
+
+# Start embedding
+statik -src=assets/build/ -include=*.html,*.js,*.json,*.css,*.png,*.svg,*.ico,*.ttf -f
+```
+
+{% hint style="info" %}
+If the `statik` command is not found when embedding, try executing.
+
+`export PATH=$PATH:$(go env GOPATH)/bin`
+{% endhint %}
+
+### Compile the project
+
+```bash
+### Get current version number, commit
+export COMMIT_SHA=$(git rev-parse --short HEAD)
+export VERSION=$(git describe --tags)
+
+# Start the build
+go build -a -o cloudreve -ldflags " -X 'github.com/cloudreve/Cloudreve/v3/pkg/conf.BackendVersion=$VERSION' -X 'github.com/cloudreve/ Cloudreve/v3/pkg/conf.LastCommit=$COMMIT_SHA'"
+```
+
+{% hint style="info" %}
+When first compiling, Go will download the relevant dependencies, which may cause this step to slow down or fail if you have a poor network. You can use [GOPROXY.IO](https://goproxy.io/zh/) to speed up the module download.
+{% endhint %}
+
+Once compiled, the final executable `cloudreve` will be generated in the project root directory.
+
+## Build Assistant
+
+You can quickly build, package etc. using the build script `build.sh` in the project root directory, which is used as follows
+
+```bash
+. /build.sh [-a] [-c] [-b] [-r]
+    a - build static resources
+    c - compile binaries
+    b - build front-end + compile binaries
+    r - cross-compile, build for release
+```
+
+## Cross-compiling
+
+Before cross-compiling, you need to enable `CGO`, properly install the GCC toolchain for the target platform and set the `CC` environment variable to the GCC compiler for the corresponding platform.
+
+For example, to cross-compile Windows/AMD64 on a Linux/AMD64 host platform.
+
+```bash
+export GOOS=windows
+export GOARCH=amd64
+export CC=x86_64-w64-mingw32-gcc
+export CGO_ENABLED=1
+
+go build
+```

+# Configuration files
+
+## Configuration file
+
+When you start Cloudreve for the first time, Cloudreve creates a configuration file named `conf.ini` in the same level directory.
+
+You can also specify the path to the configuration file by adding the `-c` parameter at startup:
+
+```
+./cloudreve -c /path/to/conf.ini
+```
+
+An example of a complete configuration file is as follows.
+
+```d
+[System]
+; Run mode
+Mode = master
+; Listening port
+Listen = :5000
+; Whether to enable Debug
+Debug = false
+; Session key, usually generated automatically at first boot

+
+## Using MySQL
+
+By default, Cloudreve uses the built-in SQLite database and creates the database file `cloudreve.db` in the same directory. If you want to use MySQL, please add the following to the configuration file and restart Cloudreve.
+
+Note that Cloudreve only supports MySQL versions greater than or equal to 5.7.
+```
+[Database]
+; database type, currently sqlite/mysql/mssql/postgres is supported
+Type = mysql
+MySQL port
+Port = 3306
+; Username
+User = root
+; Password
+Password = root
+; Database address
+Host = 127.0.0.1
+; Database name
+Name = v3
+; Data table prefix
+TablePrefix = cd
+; Character set
+Charset = utf8
+```
+
+{% hint style="info" %}
+After changing the database configuration, Cloudreve will reinitialize the database and the old data will be lost.
+{% endhint %}
+
+## Using Redis
+
+You can add Redis-related settings to your configuration file.
+
+```
+[Redis]
+Server = 127.0.0.1:6379
+Password = your password
+DB = 0
+```
+
+{% hint style="info" %}
+Please specify a DB for Cloudreve that is not used by other services to avoid conflicts.
+{% endhint %}
+
+After restarting Cloudreve, you can note the console output to determine if Cloudreve successfully connected to the Redis server. When using Redis, the following will be taken over by Redis.
+
+* User sessions (no more lost login sessions after restarting Cloudreve)
+* Data table HF record query cache (e.g. storage policies, settings entries)
+* Callback sessions
+* OneDrive credentials
+
+## Enable HTTPS
+
+{% hint style="info" %}
+If you are using Cloudreve as a web server reverse proxy, it is recommended that you configure SSL in your web server, the how to described in this section is only valid if you are using Cloudreve's built-in web server.
+{% endhint %}
+
+In the configuration file add.
+
+```
+[SSL]
+Listen = :443
+CertPath = C:\Users\i\Documents\fullchain.pem
+KeyPath = C:\Users\i\Documents\privkey.pem
+```
+
+where `CertPath` and `KeyPath` are the SSL certificate and private key paths, respectively. Save and restart Cloudreve to take effect.
