3	+	## Build
4	+
5	+	To build an OCI image, use the `build` option and name the OCI image with the `-t` tag variable:
6	+	```bash
7	+	buildah build -t registry.whatever.org/image-name
8	+	```
9	+
10	+	You can also add metadata to it like a description with the `--annotation` variable, by adding:
11	+	```bash
12	+	--annotation 'org.opencontainers.image.description=Description of the OCI image'
13	+	```
14	+
15	+	> View more metadata options for OCI images: https://github.com/opencontainers/image-spec/blob/main/annotations.md#back-compatibility-with-label-schema
16	+
17	+	To add another metadata, such as the vendor, you would simply add another `--annotation` variable. Here's a full example:
18	+	```bash
19	+	buildah build -t registry.whatever.org/image-name --annotation 'org.opencontainers.image.description=Description of the OCI image' --annotation 'org.opencontainers.image.vendor=Vendor Name'
20	+	```
21	+
22	+	## Push
23	+
24	+	It's straight-forward with the `push` option. Just push:
25	+	```
26	+	buildah push registry.whatever.org/image-name
27	+	```
