-
-```bash
-./scripts/dockerpush.sh

+## Building releases and Docker containers
+
+### With GoReleaser
+
+GoToSocial uses the release tooling [GoReleaser](https://goreleaser.com/intro/) to make multiple-architecture + Docker builds simple.
+
+GoReleaser is also used by GoToSocial for building and pushing Docker containers.
+
+Normally, these processes are handled by Drone (see CI/CD above). However, you can also invoke GoReleaser manually for things like building snapshots.
+
+To do this, first [install GoReleaser](https://goreleaser.com/install/).
+
+Then, to create snapshot builds, do:
+
+```bash
+goreleaser release --rm-dist --snapshot
+```
+
+If all goes according to plan, you should now have a bunch of multiple-architecture binaries and tars inside the `./dist` folder, and a snapshot Docker image should be built (check your terminal output for version).
+
+### Manually
+
+If you prefer a simple approach with fewer dependencies, you can also just build a Docker container manually in the following way:
+
+```bash
+./scripts/build.sh && docker build -t superseriousbusiness/gotosocial:latest .
+```
+
 ## Financial Compensation
 
 Right now there's no structure in place for financial compensation for pull requests and code. This is simply because there's no money being made on the project apart from the very small weekly Liberapay donations.
