+
+# Usage
+
+[docker-compose](https://docs.docker.com/compose/) (recommended)
+```
+---
+version: "2.1"
+services:
+  nzbget:
+    image: nzbgetcom/nzbget:latest
+    container_name: nzbget
+    environment:
+      - PUID=1000
+      - PGID=1000
+      - TZ=Europe/London
+      - NZBGET_USER=nzbget     #optional
+      - NZBGET_PASS=tegbzn6789 #optional
+    volumes:
+      - /path/to/config:/config
+      - /path/to/downloads:/downloads #optional
+    ports:
+      - 6789:6789
+    restart: unless-stopped
+```
+
+[docker cli](https://docs.docker.com/engine/reference/commandline/cli/)
+```
+docker run -d \
+  --name=nzbget \
+  -e PUID=1000 \
+  -e PGID=1000 \
+  -e TZ=Europe/London \
+  -e NZBGET_USER=nzbget `#optional` \
+  -e NZBGET_PASS=tegbzn6789 `#optional` \
+  -p 6789:6789 \
+  -v /path/to/config:/config \
+  -v /path/to/downloads:/downloads `#optional` \
+  --restart unless-stopped \
+  nzbgetcom/nzbget:latest
+```
+
+# Supported environment variables
+
+NZBGet container can be configured by passing environment variables to it. This can be done in docker-compose mode by specifying `environment:` and in cli mode by using -e switch.
+
+| Parameter	  | Description
+|:------------|-
+| PUID        | UserID (see below)
+| PGID        | GroupID (see below)
+| TZ          | Timezone
+| NZBGET_USER | User name for web auth
+| NZBGET_PASS | Password for web auth
+
+# User / Group Identifiers
+
+When using volumes (-v flags) permissions issues can arise between the host OS and the container. To avoid this problem we allow to specify the user PUID and group PGID.
+
+The example above uses PUID=1000 and PGID=1000. To find the required ids, run `id user`:
+```
+$ id user
+uid=1000(user) gid=1000(users) groups=1000(users)
+```
+
+# Building locally
+
+For development purposes can be used Dockerfile or docker-compose file from official repository (`docker` folder): 
+
+```
+git clone https://github.com/nzbgetcom/nzbget.git
+cd docker
+docker compose up
+-or-
+docker build . -t nzbget-local
+```
+
+Dockerfile supports next build arguments:
+
+| Argument	      | Description
+|:----------------|-
+| NZBGET_RELEASE  | Branch name or tag to build from
+| UNRAR_VERSION   | Unrar version
+| MAKE_JOBS       | Number of make jobs for speed up build
