+# Fluent Bit Helm chart
+
+[Fluent Bit](https://fluentbit.io) is a fast and lightweight log processor and forwarder or Linux, OSX and BSD family operating systems.
+
+## Installation
+
+To add the `fluent` helm repo, run:
+
+```sh
+helm repo add fluent https://fluent.github.io/helm-charts
+```
+
+To install a release named `fluent-bit`, run:
+
+```sh
+helm install fluent-bit fluent/fluent-bit
+```
+
+## Chart values
+
+```sh
+helm show values fluent/fluent-bit
+```
+
+## Using Lua scripts
+Fluent Bit allows us to build filter to modify the incoming records using custom [Lua scripts.](https://docs.fluentbit.io/manual/pipeline/filters/lua)
+
+### How to use Lua scripts with this Chart
+
+First, you should add your Lua scripts to `luaScripts` in values.yaml, for example:
+
+```yaml
+luaScripts:
+  filter_example.lua: |
+    function filter_name(tag, timestamp, record)
+        -- put your lua code here.
+    end
+```
+
+After that, the Lua scripts will be ready to be used as filters. So next step is to add your Fluent bit [filter](https://docs.fluentbit.io/manual/concepts/data-pipeline/filter) to `config.filters` in values.yaml, for example:
+
+```yaml
+config:
+  filters: |
+    [FILTER]
+        Name    lua
+        Match   <your-tag>
+        script  /fluent-bit/scripts/filter_example.lua
+        call    filter_name
+```
+Under the hood, the chart will:
+- Create a configmap using `luaScripts`.
+- Add a volumeMounts for each Lua scripts using the path `/fluent-bit/scripts/<script>`.
+- Add the Lua script's configmap as volume to the pod.
+
+### Note
+Remember to set the `script` attribute in the filter using `/fluent-bit/scripts/`, otherwise the file will not be found by fluent bit.
