+## FEATURES
+
+- supports csv, json or ascii format input from files or stdin
+- split any tabular input data by character or regular expression into columns
+- add headers if input data doesn't contain them (automatically or manually)
+- print tabular data as ascii table, org-mode, markdown, csv, shell-evaluable or yaml format
+- filter rows by regular expression (saves a call to `| grep ...`)
+- filter rows by column filter
+- filters may also be negations eg `-Fname!=cow.*` or `-v`
+- modify cells wih regular expressions
+- reduce columns by specifying which columns to show, with regex support
+- color support
+- sort by any field[s], multiple sort modes are supported
+- shell completion for options
+- regular used options can be put into a config file
+- filter TUI where where you can interactively sort and filter rows

    markdown which prints a Markdown table, yaml, which prints yaml encoding
    and CSV mode, which prints a comma separated value file.

+    A special output mode ist the Template mode, activated with the option
+    "--template". Template language is the Golang template language:
+    <https://pkg.go.dev/text/template>. You can also use lot's of additional
+    functions from: <https://masterminds.github.io/sprig/>. Here's an
+    example:
+
+        > kubectl get pods | tablizer --template "{{.name}} is {{.status}}"
+        alertmanager-kube-prometheus-alertmanager-0 is Running
+        grafana-fcc54cbc9-bk7s8 is Running
+
+    You can use header names as variables.
+
  PUT FIELDS TO CLIPBOARD
    You can let tablizer put fields to the clipboard using the option "-y".
    This best fits the use-case when the result of your filtering yields
