+# Quick Start
+
+## Docker + Emphemeral SQLite
+
+You can run this using Docker:
+
+```
+docker run --rm -p 3000:3000 -p 50332:50332 -v $HOME:$HOME ghcr.io/dolcetriade/blade:0.1 --db_path sqlite:///tmp/blade.db -l
+```
+
+Then you can run:
+
+```
+bazel test -c opt --bes_backend=grpc://localhost:50332 --bes_results_url="http://localhost:3000/invocation/" //...
+```
+
+If you want the database to be persistent, you bind mount a location in. You need to bind mount `$HOME` so you can access build logs. If you have a local remote cache, you can use that instead. You can override bytestream locations with alternate locations by passing in `-o bytestream://original.com=http://127.0.0.1:3834`. This flag can be passed in multiple times. It might be useful to set the bazel flag `--remote_bytestream_uri_prefix`. If you use a remote cache, you can omit the `-l` flag which prevents reading local files, which is a security risk since this would allow people to read arbitrary files on the host.
+
+## PostgreSQL
+
+There isn't a fully fleshed out example for this... Assuming you can access postgresql from the docker container:
+
+```
+docker run --rm -p 3000:3000 -p 50332:50332 ghcr.io/dolcetriade/blade:0.1 --db_path postgres://username:password@localhost/diesel_demo
+```
