 ## Current Version: [23.6.1](https://github.com/SolidNerd/docker-bookstack/blob/master/Dockerfile)
 
-### Changes
+## Changes
 
 The version 23.6.0 is broken due to a bad `.env` configuration created by the
 entrypoint script. This is fixed in version 23.6.1.
 
-In 0.28.0 we changed the container http port from 80 to 8080 to allow root privileges to be dropped

-### Quickstart
+## Quickstart
 
 With Docker Compose is a Quickstart very easy. Run the following command:
 
-```
+```bash
 docker-compose up
 ```
 
-and after that open your Browser and go to [http://localhost:8080](http://localhost:8080) . You can login with username 'admin@admin.com' and password 'password'.

 Note that if you want to use LDAP, `$` has to be escape like `\$`, i.e. `-e "LDAP_USER_FILTER"="(&(uid=\${user}))"`
 
 Networking changed in Docker v1.9, so you need to do one of the following steps.
 
-#### Docker < v1.9
+### Docker < v1.9
 
 1. MySQL Container:
 
-```bash
-docker run -d \
--p 3306:3306 \
--e MYSQL_ROOT_PASSWORD=secret \
--e MYSQL_DATABASE=bookstack \
--e MYSQL_USER=bookstack \
--e MYSQL_PASSWORD=secret \
---name bookstack_db \
-mysql:5.7.21
-```
+   ```bash
+   docker run -d \
+   -p 3306:3306 \
+   -e MYSQL_ROOT_PASSWORD=secret \
+   -e MYSQL_DATABASE=bookstack \
+   -e MYSQL_USER=bookstack \
+   -e MYSQL_PASSWORD=secret \
+   --name bookstack_db \
+   mysql:5.7.21
+   ```
+
 2. BookStack Container:
 
-```bash
-docker run -d --link bookstack_db_:mysql \
--p 8080:8080 \
---name bookstack_23.6.1 \
-solidnerd/bookstack:23.6.1
-```
+   ```bash
+   docker run -d --link bookstack_db_:mysql \
+   -p 8080:8080 \
+   --name bookstack_23.6.1 \
+   solidnerd/bookstack:23.6.1
+   ```
 
-#### Docker 1.9+
+### Docker 1.9+
 
 1. Create a shared network:
 
-```bash
-docker network create bookstack_nw
-```
+   ```bash
+   docker network create bookstack_nw
+   ```
 
 2. Run MySQL container :
 
-```bash
-docker run -d --net bookstack_nw  \
--e MYSQL_ROOT_PASSWORD=secret \
--e MYSQL_DATABASE=bookstack \
--e MYSQL_USER=bookstack \
--e MYSQL_PASSWORD=secret \
- --name="bookstack_db" \
- mysql:5.7.21
-```
+   ```bash
+   docker run -d --net bookstack_nw  \
+   -e MYSQL_ROOT_PASSWORD=secret \
+   -e MYSQL_DATABASE=bookstack \
+   -e MYSQL_USER=bookstack \
+   -e MYSQL_PASSWORD=secret \
+    --name="bookstack_db" \
+    mysql:5.7.21
+   ```
 
 3. Run BookStack Container
 
-```bash
-docker run -d --net bookstack_nw \
--e DB_HOST=bookstack_db:3306 \
--e DB_DATABASE=bookstack \
--e DB_USERNAME=bookstack \
--e DB_PASSWORD=secret \
--e APP_URL=http://example.com \
--p 8080:8080 \
---name="bookstack_23.6.1" \
- solidnerd/bookstack:23.6.1
-```
+   ```bash
+   docker run -d --net bookstack_nw \
+   -e DB_HOST=bookstack_db:3306 \
+   -e DB_DATABASE=bookstack \
+   -e DB_USERNAME=bookstack \
+   -e DB_PASSWORD=secret \
+   -e APP_URL=http://example.com \
+   -p 8080:8080 \
+   --name="bookstack_23.6.1" \
+    solidnerd/bookstack:23.6.1
+   ```
+
+    The APP_URL parameter should be the base URL for your BookStack instance without
+    a trailing slash. For example:

-APP_URL=http://example.com
+    `APP_URL=http://example.com`
 
-#### Volumes
-To access your `.env` file and important bookstack folders on your host system change `<HOST>` in the following line to your host directory and add it then to your run command:

 --mount type=bind,source=<HOST>/.env,target=/var/www/bookstack/.env \
 -v <HOST>:/var/www/bookstack/public/uploads \
 -v <HOST>:/var/www/bookstack/storage/uploads
 ```
-In case of a windows host machine the .env file has to be already created in the host directory otherwise a folder named .env will be created.
 
-After these steps you can visit [http://localhost:8080](http://localhost:8080) . You can login with username 'admin@admin.com' and password 'password'.
