+### Self-hosted runners
+
+Self-hosted runners need to set env. variable `ImageOS` to one of the following, since the action
+uses that to download assets:

+| ubuntu18 | ubuntu-18.04
+| ubuntu20 | ubuntu-20.04

-#### Authenticating with Postgres in Phoenix
+### Example (Gleam on Ubuntu without OTP)
 
-When using the Phoenix example above, the `postgres` container has some
+```yaml
-default authentication set up. Specifically, it expects a username of
+# create this in .github/workflows/ci.yml
-"postgres", and a password of "postgres". It will be available at
+on: push
-`localhost:5432`.
 
-The simplest way of setting these auth values in CI is by checking for the
+jobs:
-`GITHUB_ACTIONS` environment variable that is set in all workflows:
+  test:
-
+    runs-on: ubuntu-latest
-```elixir
+    steps:
-# config/test.exs
+      - uses: actions/checkout@v2
-
+      - uses: erlef/setup-beam@v1
-use Mix.Config
+        with:
-
+          otp-version: false
-# Configure the database for local testing
+          gleam-version: '0.19.0-rc3'
-config :app, App.Repo,
+      - run: gleam check
-  database: "my_app_test",
-  hostname: "localhost",
-  pool: Ecto.Adapters.SQL.Sandbox
-
-# Configure the database for GitHub Actions
-if System.get_env("GITHUB_ACTIONS") do
-  config :app, App.Repo,
-    username: "postgres",
-    password: "postgres"
-end
 ```
 
+**Note**: the `otp-version: false` input is only applicable when installing Gleam.
+
+## Environment variables
+
+Base installation folders (useful for e.g. fetching headers for NIFs) are available in the following
+environment variables:
+
+- `INSTALL_DIR_FOR_ELIXIR`: base folder for Erlang/OTP
+- `INSTALL_DIR_FOR_GLEAM`: base folder for Elixir
+- `INSTALL_DIR_FOR_OTP`: base folder for Gleam
+- `INSTALL_DIR_FOR_REBAR3`: base folder for `rebar3`

 ## Elixir Problem Matchers
 
-The Elixir Problem Matchers in this repository are adapted from [here](https://github.com/fr1zle/vscode-elixir/blob/45eddb589acd7ac98e0c7305d1c2b24668ca709a/package.json#L70-L118). See [MATCHER_NOTICE](MATCHER_NOTICE.md) for license details.

+
+## Action versioning
+
+`setup-beam` has three version paths, described below, for example version `1.8.0`:
+
+- `@v1`: the latest in the `1.y.z` series (this tag is movable),
+- `@v1.8`: the latest in the `1.8.z` series (this tag is movable),
+- `@v1.8.0`: release `1.8.0` (this tag is not movable).
+
+We make a real effort to not introduce incompatibilities without changing the major
+version number. To be extra safe against changes causing issues in your CI you should specify
+an exact version with `@vx.y.z`.
