+# LocalAI website
+
+LocalAI documentation website
+
+## Requirement
+In this project, the Docsy theme component is pulled in as a Hugo module, together with other module dependencies:
+
+```bash
+$ hugo mod graph
+hugo: collected modules in 566 ms
+hugo: collected modules in 578 ms
+github.com/google/docsy-example github.com/google/docsy@v0.5.1-0.20221017155306-99eacb09ffb0
+github.com/google/docsy-example github.com/google/docsy/dependencies@v0.5.1-0.20221014161617-be5da07ecff1
+github.com/google/docsy/dependencies@v0.5.1-0.20221014161617-be5da07ecff1 github.com/twbs/bootstrap@v4.6.2+incompatible
+github.com/google/docsy/dependencies@v0.5.1-0.20221014161617-be5da07ecff1 github.com/FortAwesome/Font-Awesome@v0.0.0-20220831210243-d3a7818c253f
+```
+
+If you want to do SCSS edits and want to publish these, you need to install `PostCSS`
+
+```bash
+npm install
+```
+
+## Running the website locally
+
+Building and running the site locally requires a recent `extended` version of [Hugo](https://gohugo.io).
+You can find out more about how to install Hugo for your environment in our
+[Getting started](https://www.docsy.dev/docs/getting-started/#prerequisites-and-installation) guide.
+
+Once you've made your working copy of the site repo, from the repo root folder, run:
+
+```
+hugo server
+```
+
+## Running a container locally
+
+You can run docsy-example inside a [Docker](https://docs.docker.com/)
+container, the container runs with a volume bound to the `docsy-example`
+folder. This approach doesn't require you to install any dependencies other
+than [Docker Desktop](https://www.docker.com/products/docker-desktop) on
+Windows and Mac, and [Docker Compose](https://docs.docker.com/compose/install/)
+on Linux.
+
+1. Build the docker image 
+
+   ```bash
+   docker-compose build
+   ```
+
+1. Run the built image
+
+   ```bash
+   docker-compose up
+   ```
+
+   > NOTE: You can run both commands at once with `docker-compose up --build`.
+
+1. Verify that the service is working. 
+
+   Open your web browser and type `http://localhost:1313` in your navigation bar,
+   This opens a local instance of the docsy-example homepage. You can now make
+   changes to the docsy example and those changes will immediately show up in your
+   browser after you save.
+
+### Cleanup
+
+To stop Docker Compose, on your terminal window, press **Ctrl + C**. 
+
+To remove the produced images run:
+
+```console
+docker-compose rm
+```
+For more information see the [Docker Compose
+documentation](https://docs.docker.com/compose/gettingstarted/).
+
+## Troubleshooting
+
+As you run the website locally, you may run into the following error:
+
+```
+➜ hugo server
+
+INFO 2021/01/21 21:07:55 Using config file: 
+Building sites … INFO 2021/01/21 21:07:55 syncing static files to /
+Built in 288 ms
+Error: Error building site: TOCSS: failed to transform "scss/main.scss" (text/x-scss): resource "scss/scss/main.scss_9fadf33d895a46083cdd64396b57ef68" not found in file cache
+```
+
+This error occurs if you have not installed the extended version of Hugo.
+See this [section](https://www.docsy.dev/docs/get-started/docsy-as-module/installation-prerequisites/#install-hugo) of the user guide for instructions on how to install Hugo.
+
+Or you may encounter the following error:
+
+```
+➜ hugo server
+
+Error: failed to download modules: binary with name "go" not found
+```
+
+This error occurs if you have not installed the `go` programming language on your system.
+See this [section](https://www.docsy.dev/docs/get-started/docsy-as-module/installation-prerequisites/#install-go-language) of the user guide for instructions on how to install `go`.
