+# 🔑 JSON Variable Key/Value Lookup
+
+Action to perform a lookup from a JSON string containing a simple array of
+key/value pairs.
+
+## json-key-value-lookup-action
+
+## Usage Example
+
+Pass a JSON string as an input to the action, along with the key to lookup.
+The action will return the corresponding value, using JQ to pass the JSON.
+
+```yaml
+- name: "Get ticket reference from JSON lookup table"
+  uses: lfit/releng-reusable-workflows/.github/actions/json-key-value-lookup-action@main
+  with:
+      json: ${{ inputs.issue_id_lookup_json }}
+      key: ${{ env.key }}
+```
+
+## Example JSON Variable
+
+Provide JSON as an array containing simple key/value pairs, as shown below.
+
+```json
+[
+    { "key": "dependabot[bot]", "value": "CIMAN-33" },
+    { "key": "John Doe", "value": "CIMAN-1000" }
+]
+```
+
+In the example above, the repository has a variable configured called: ISSUE_ID_LOOKUP_JSON
+
+Set/define this under:
+
+[ Github Repository ] -> Settings -> Secrets and variables -> Actions -> Variables
+
+## Inputs
+
+The action does not have any default values and both input parameters are mandatory.
+
+| Variable Name | Required | Description                                |
+| ------------- | -------- | ------------------------------------------ |
+| JSON          | True     | JSON dictionary containing key/value pairs |
+| KEY           | True     | Key to use to extract corresponding value  |
+| DEFAULT       | False    | Default value in the event lookup fails    |
+
+### Note 🗒️
+
+In the event of a lookup failure, the action will exit with an error. Specifying
+a default value will prevent this failure from taking place, allowing the calling
+action/workflow to take alternative action, preventing the failure from
+stopping the entire pipeline.
+
+## Outputs
+
+| Variable Name | Description                                            |
+| ------------- | ------------------------------------------------------ |
+| VALUE         | The value corresponding to the key (provided as input) |
+
+## Requirements/Dependencies
+
+Ensure validated JSON (in the format specified above) is in the variable.
+The action performs validation before the lookup and will otherwise throw
+an error.
+
+If the key is not represented in the lookup table, the action will exit with an
+error. This behaviour will result in the calling action/workflow failing.
+Prevent this by setting a default return value, allowing upstream code to take
+alternative paths.
