+# Build DragonflyDB From Source
+
+## Running the server
+
+Dragonfly runs on linux. It uses relatively new linux specific [io-uring API](https://github.com/axboe/liburing)
+for I/O, hence it requires `Linux verion 5.10` or later.
+Debian/Bullseye, `Ubuntu 20.04.4` or later fit these requirements.
+
+### WARNING: Building from source on older kernels WILL NOT WORK.
+
+If your host machine does not have at least `Linux verion 5.10` or later, we suggest you choose a [Dockerized Quick Start](/docs/quick-start/).
+
+
+## Step 1
+
+```bash
+git clone --recursive https://github.com/dragonflydb/dragonfly && cd dragonfly
+```
+
+## Step 2
+```bash
+# Install dependencies
+sudo apt install ninja-build libunwind-dev libboost-fiber-dev libssl-dev \
+     autoconf-archive libtool cmake g++
+```
+
+## Step 3
+
+```bash
+# Configure the build
+./helio/blaze.sh -release
+
+# Build
+cd build-opt && ninja dragonfly
+
+```
+
+## Step 4
+```bash
+# Run
+./dragonfly --alsologtostderr
+
+```
+
+Dragonfly DB will answer to both `http` and `redis` requests out of the box!
+
+You can use `redis-cli` to connect to `localhost:6379` or open a browser and visit `http://localhost:6379`
+
+## Step 5
+
+Connect with a redis client
+
+```bash
+redis-cli
+127.0.0.1:6379> set hello world
+OK
+127.0.0.1:6379> keys *
+1) "hello"
+127.0.0.1:6379> get hello
+"world"
+127.0.0.1:6379> 
+```
+
+## Step 6
+
+Continue being great and build your app with the power of DragonflyDB!
