+# Using Colima with Docker
+
+[Colima](https://github.com/abiosoft/colima) is a container runtime which
+integrates with Docker's tooling and can be configured in various ways.
+
+As of Colima v0.4.0 it's recommended to set the active Docker context to use
+Colima. After the context is set testcontainers-go will automatically be
+configured to use Colima.
+
+```bash
+$ docker context ls
+NAME        DESCRIPTION                               DOCKER ENDPOINT                                      KUBERNETES ENDPOINT      ORCHESTRATOR
+colima      colima                                    unix:///Users/foobar/.colima/default/docker.sock
+default *   Current DOCKER_HOST based configuration   unix:///Users/foobar/.colima/docker.sock
+
+$ docker context use colima
+colima
+Current context is now "colima"
+
+$ docker context ls
+NAME       DESCRIPTION                               DOCKER ENDPOINT                                      KUBERNETES ENDPOINT       ORCHESTRATOR
+colima *   colima                                    unix:///Users/foobar/.colima/default/docker.sock
+default    Current DOCKER_HOST based configuration   unix:///var/run/docker.sock
+```
+
+If you're using an older version of Colima or have other applications that are
+unaware of Docker context the following workaround is available:
+
+1. Locate your Docker Socket, see: [Colima's FAQ - Docker Socket Location](https://github.com/abiosoft/colima/blob/main/docs/FAQ.md#docker-socket-location)
+
+2. Set the `DOCKER_HOST` environment variable to match the located Docker Socket
+
+    * Example: `export DOCKER_HOST="unix://${HOME}/.colima/default/docker.sock"`
+
+3. As of testcontainers-go v0.14.0 set `TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE`
+   to `/var/run/docker.sock` as the default value refers to your `DOCKER_HOST`
+   environment variable.
+
+    * Example: `export TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE="/var/run/docker.sock"`
