+
+### Docker
+
+Get the [Docker image](https://hub.docker.com/repository/docker/ankane/pgvector) with:
+
+```sh
+docker pull ankane/pgvector
+```
+
+This adds pgvector to the [Postgres image](https://hub.docker.com/_/postgres).
+
+You can also build the image manually
+
+```sh
+git clone --branch v0.1.3 https://github.com/ankane/pgvector.git
+cd pgvector
+docker build -t pgvector .
+```
+
+### Homebrew
+
+On Mac with Homebrew Postgres, you can use:
+
+```sh
+brew install ankane/brew/pgvector
+```
+
+### PGXN
+
+Install from the [PostgreSQL Extension Network](https://pgxn.org/dist/vector) with:
+
+```sh
+pgxn install vector
+```
+
+## Hosted Postgres
+
+Some Postgres providers only support specific extensions. To request a new extension:
