 ## Why a fork?
 
 SQLite has solidified its place in modern technology stacks, embedded in nearly any computing device you can think of. Its open source nature and public domain availability make it a popular choice for modification to meet specific use cases.

 ## Launch a primary instance
 
 ```
-docker run --name some-sqld -e SQLD_NODE=primary -d ghcr.io/libsql/sqld:main
+docker run --name some-sqld -p 8080:8080 -ti \ 
+    -e SQLD_NODE=primary \
+    ghcr.io/tursodatabase/libsql-server:main

 ## Launch a replica instance
 
 ```
-docker run --name some-sqld -e SQLD_NODE=replica -D SQLD_PRIMARY_URL=https://<host>:<port> -d ghcr.io/libsql/sqld:main
+docker run --name some-sqld-replica -p 8081:8080 -ti 
+    -e SQLD_NODE=replica \
+    -e SQLD_PRIMARY_URL=https://<host>:<port> \

+## Running on Apple Silicon

 ```
 
+_Note: the latest images for arm64 are available under the tag
+`ghcr.io/tursodatabase/libsql-server:latest-arm`, however for tagged versions,
+and stable releases please use the x86_64 versions via Rosetta._

 # How to extend this image
 
+## Data Persistance
+
+Database files are stored in the `/var/lib/sqld` in the image. To persist the 
+database across runs, mount this location to either a docker volume or a bind 
+mount on your local disk.
+
+```
+docker run --name some-sqld -ti \
+    -v ./.data/libsql \
+    -e SQLD_NODE=primary \ 
+    ghcr.io/tursodatabase/libsql-server:main
+```
+
 ## Environment variables
 
 ### `SQLD_NODE`
 
-The `SQLD_NODE` environment variable configures the type of the launched instance. Possible values are: `primary` (default), `replica`, and `standalone`.
-Please note that replica instances also need the `SQLD_PRIMARY_URL` environment variable to be defined.
+**default:** `primary`
+
+The `SQLD_NODE` environment variable configures the type of the launched
+instance. Possible values are: `primary` (default), `replica`, and `standalone`.
+Please note that replica instances also need the `SQLD_PRIMARY_URL` environment
+variable to be defined.
 
 ### `SQLD_PRIMARY_URL`
 
 The `SQLD_PRIMARY_URL` environment variable configures the gRPC URL of the primary instance for replica instances.
 
 **See:** `SQLD_NODE` environment variable
+
+### `SQLD_DB_PATH`
+
+**default:** `iku.db`
+
+The location of the db file inside the container. Specifying only a filename
+will place the file in the default directory inside the container at
+`/var/lib/sqld`.
+
+### `SQLD_HTTP_LISTEN_ADDR`
+
+**default:** `0.0.0.0:8080`
+
+Defines the HTTP listen address that sqld listens on and clients will connect
+to. Recommended to leave this on the default port and remap ports at the
+container networking level.
+
+### `SQLD_GRPC_LISTEN_ADDR`
+
+**default:** `0.0.0.0:5001`
+
+Defines the GRPC listen address and port for sqld. Primarily used for
+inter-node communication. Recommended to leave this on default.
+
+
+## Docker Compose
+
+Simple docker compose for local development:
+
+```
+version: "3"
+services:
+  db:
+    image: ghcr.io/tursodatabase/libsql-server:main
+    platform: linux/amd64
+    ports:
+      - "8080:8080"
+      - "5001:5001"
+    # environment:
+    #   - SQLD_NODE=primary
+    volumes:
+      - ./data/libsql:/var/lib/sqld
+```
