+## Project Goals
+
+The idea behind this  project is to build a small commandline   tool to 
+manage an ElasticSearch cluster. 
+
+There  will  be no  GUI,  no  web interface,  no  public  API of  some
+sort. TUI subcommands maybe added.
+
+The  programming  language  used  for  this  project  will  always  be
+[GOLANG](https://go.dev/)  with  the  exception of  the  documentation
+([Perl POD](https://perldoc.perl.org/perlpod)) and the Makefile.
+
+# Contributing
+
+Everyone can contribute to this project except you are using "AI"
+(LLM) generated content (code, issue text, etc), even if only a part
+of it is. This is a human made project. It is being made to have fun
+at work and learning coding and APIs. If you want fast results without
+the hassle to invest time then please refrain from
+contributing.
+
+You can contribute to this project in various ways:
+
+## Open an issue
+
+If you encounter  a problem or don't understand how  the program works
+or if you think the documentation is unclear, please don't hesitate to
+open an issue.
+
+Please add as much information about the case as possible, such as:
+
+- Your environment (operating system etc)
+- program version
+- Input data. Please replace sensitive information with mock data!
+- Actual program output.
+- Expected program output.
+- Error message - if any.
+
+Be aware  that I  am working on  this (and some  other) project  in my
+spare  time which  is scarce.   Therefore  please don't  expect me  to
+respond to  your query within  hours or even  days. Be patient,  but I
+WILL respond.
+
+## Pull Requests
+
+Code and documentation help is  always much appreciated! Please follow
+thes guidelines to successfully contribute:
+
+-  Every  pull   request  shall  be  based   on  latest  `development`
+  branch. `main` is only used for releases.
+  
+- Execute the  unit tests before committing: `make  test`. There shall
+  be no errors.
+  
+- Strive  to be  backwards compatible  so that  users who  are already
+  using the program  don't have to change their habits  - unless it is
+  really neccessary.
+
+- Try to add a unit test for your addition.
+
+- Don't ever change existing unit tests!
+
+- Add a meaningful and comprehensive rationale about your contribution:
+  - Why do you think it might be useful for others?
+  - What did you actually change or add?
+  - Is there an open issue which  this PR fixes and if so, please link
+    to that issue.
+
+- [Re-]format your code with `gofmt -s`.
+
+- Avoid unneccesary dependencies, especially for very small functions.
+
+- **If** a  new dependency is being added, it  must be compatible with
+  our [license agreement](LICENSE).
+  
+- You  need to accept  that the  code or documentation  you contribute
+  will be redistributed under the  terms of said license agreement. If
+  your  contribution  is  considerably  large  or  if  you  contribute
+  regularly, then  feel free  to add  your name and  if you  want your
+  email    address     to    the    *AUTHORS*    section     of    the
+  manual page.
+
+- Adhere to the above mentioned project goals.
+
+-  If  you are  unsure if  your addition or  change will  be accepted,
+  better ask before starting coding. Open an issue about your proposal
+  and let's  discuss it! That way  we avoid doing unnessesary  work on
+  both sides.
+    
+Each pull  request will be  carefully reviewed and  if it is  a useful
+addition  it  will  be  accepted. However,  please  be  prepared  that
+sometimes a  PR will be  rejected.  The reasons  may vary and  will be
+documented.   Perhaps the  above guidelines  are not  matched, or  the
+addition seems  to be not so  useful from my perspective,  maybe there
+are  too  much  changes  or  there  might  be  changes  I  don't  even
+understand.
+
+But whatever happens: your contribution is always welcome!

-
-VERSION:
-   v0.0.3
-
-COMMANDS:
-   search, /       search within an index
-   index, i        manage indicies
-   snapshot, snap  manage snapshots

-```
-
-Configure `esctl` with environment variables:
-
-- `ES_URI`: elasticsearch uri
-- `ES_USER`: username
-- `ES_PASS`: password
-
-Or create a config file such as this:
-
-```yaml
-clusters:
-  default:
-    uri: https://es.foo.bar:9200/
-    user: elastic
-    pass: 123456

-    user: elastic
-    pass: asdasdasd
-```
-
-and specify it with `-c configfile`.  You may also put clusters into a
-default config file in `~/.config/esctl/config.yaml`. In this case you
-can omit `-c ...`.
-
-If you want to  work on a specific cluster, specify  its name with the
-global `-C` option.

 ## Introduction
 
-FIXME
+This is a handy cli tool which interfaces to an elasticsearch cluster
+(or two of them if you're using cross cluster replication). It is a
+work-in-progress project yet, things might change occasionally. Expect
+a stable release once we reach major version 1.0.0.
+
+Features:
+
+- Configuration of cluster credentials using environment vars or
+  config file. Multiple clusters can be configured. `esctl cluster ls`
+  shows which one is reachable.
+- Shell completion support (bash, zsh and fish). Put this into your
+  rc: `source <(esctl completion bash)`.
+- Cluster settings can be viewed and modified.
+- Search: you can search indices using full text or by fields, select
+  logical condition (OR, AND), use PIT, limit datetime (ES date math
+  can be used), etc. It is however not yet possible to create
+  recursive searches like: `(cond1 AND cond2) OR (cond3 OR cond4)`.
+- Cross cluster replication (ccr): view, pause, resume, delete
+  replication. You can also manage follower configuration.
+- Index management: manage aliases, create, modify, delete indices,
+  display field mappings etc. Automatic rollover of aliases supported.
+- Index template management: create, modify, delete etc
+- Index alias management: create, modify, delete etc
+- Node management: only list nodes yet.
+- Shard management: only list shards yet.
+- Snapshot management: only list snapshots yet.
+- ILM management: list, create, delete etc. 
+- Task management: list and cancel tasks
+- Role management: only list roles yet. There's also a `role diff`
+  subcommand, which is for internal use. It can be used to verify if
+  role defs in a CSV match the deployed roles.
+- API  documentation   (`api  list`  and  `api   show  <path>`)  with
+  interactive markdown pager for endpoint documentation.
+- Repl: this is an interactive REPL (read eval print loop) towards the
+  elasticsearch API. You can run API calls on the current selected
+  cluster w/o the hassle to specify the whole url, credentials etc. It
+  has line editing and history support. If `jq` is installed output
+  JSON will be syntax highlighted.
+- Doc support. You can put, delete and show docs for an index. Very
+  handy if you want to play with it. Just create a new index:
+  `esctl index create foo` and then insert docs into it for search
+  experiments:
+  ```console
+  esctl doc add -i foo '{"title":"curry in a hurry", "message":"australian thai"}'
+  ```

+## Configure
+
+Configure `esctl` with environment variables:
+
+- `ES_URI`: elasticsearch uri
+- `ES_USER`: username
+- `ES_PASS`: password
+- `ES_TOKEN`: API token, instead of user+password
+
+Or create a config file such as this:
+
+```yaml
+clusters:
+  foobar:
+    uri: https://es.foo.bar:9200/
+    user: elastic
+    pass: ******
+  other:
+    uri: https://myes.foo:9200/
+    token: ******
+```
+
+and specify it with `-c configfile`.  You may also put clusters into a
+default config file in `~/.config/esctl/config.yaml`. In this case you
+can omit `-c ...`.
+
+If you want to  work on a specific cluster, you need to make it the
+current default one. You can either manually configure it in the
+config:
+
+```yaml
+clusters:
+  foobar:
+    uri: https://es.foo.bar:9200/
+    user: elastic
+    pass: 123456
+    default: true
+```
+
+or - if the cluster already exists in the config - issue this command:
+
+```console
+esctl cluster switch foobar
+```
+
+You may also temporary set a cluster as the current default with the
+global `-C` option.
+
+The following rules apply for default cluster selection:
+
+1. If there's just one cluster configured (either via environment
+   variables or config), this one will be selected.
+2. If a cluster have been specified with `-C <name>`, use this.
+3. If there is one cluster configured with the `default` flag `true`,
+   use this one.
+   
+Use `esctl cluster ls` to check status and see which one would be
+used.
+
+Please be aware, that prior to use a cluster and send API requests to
+it, `esctl` checks the connectivity to it first.
+
+## Usage
+
+Once you have configured one or more (and marked one as the default,
+see above) elasticsearch clusters, you can start using `esctl`. Since
+there are just too many things you can do with it, we'll just outline
+a couple of examples here.
+
+To see the status of a cluster:
+
+```console
+$ esctl cluster status 
+DEFAULT                    STATUS                 
+Cluster Name               eck-cluster-dev-s1
+ES Status                  green                  
+ES Version                 9.4.2                  
+Is Leader                  true

+Long Running Tasks         2

+
+you may also add the `-v` flag to see more:
+
+```console

+
+Settings can be changed, use json path to specify a setting:
+
+```console
+$ esctl cluster settings set indices.recovery.max_bytes_per_sec:480mb
+```
+
+Searching is pretty easy. First check which indices exist:
+
+```console
+$ esctl index ls

+
+Like a dataview in kibana you can specify an index pattern for search:
+
+```console
+$ esctl search -i foo*
+{"id":"1779873299", "score":1.0000, "index":"foo2", "source":{"message":"foo bar"}}{"id":"1779870997", "score":1.0000, "index":"foo2", "source":{"message":"start","time":"27.05.2026T10:55:33+0200","title":"zeitbuchung"}}{"id":"1779870750", "score":1.0000, "index":"foo2", "source":{"message":"pause","time":"27.05.2026T10:33:45+0200","title":"zeitbuchung"}}{"id":"1779870103", "score":1.0000, "index":"foo2", "source":{"message":"punktlich gebucht","time":"27.05.2026T10:20:01+0200","title":"zeitbuchuung"}}{"id":"1779432806", "score":1.0000, "index":"foo2", "source":{"message":"strange compound 2"}}{"id":"1779432750", "score":1.0000, "index":"foo2", "source":{"message":"strange compound 1"}}{"id":"1778600947", "score":1.0000, "index":"foo2", "source":{"id":"d8d8d","user":"scip"}}{"id":"1778600945", "score":1.0000, "index":"foo2", "source":{"id":"d8d8d","user":"scip"}}{"id":"1778600857", "score":1.0000, "index":"foo2", "source":{"id":"d8d8d","user":"scip"}}{"id":"1778601788", "score":1.0000, "index":"foo2", "source":{"id":"new1","message":"live long and prosper"}}{"id":"1778601422", "score":1.0000, "index":"foo2", "source":{"id":"new1","message":"love long and prosper"}}{"id":"1779447242", "score":1.0000, "index":"foo2", "source":{"message":"australian thai","title":"curry in a hurry"}}{"id":"1779447284", "score":1.0000, "index":"foo2", "source":{"message":"german killer food","title":"wuerger burger"}}{"id":"1779364394", "score":1.0000, "index":"foo2", "source":{"id":"1","message":"non-dead human looks curious at TargetOne"}}
+```
+
+Oops, that looks gibberish. It's because `esctl` just prints the raw
+JSON search results. There are multiple ways to post-process them:
+
+You can use `jq` (here, we're using `-l 1` to limit the output to 1 document):
+
+```console
+$ esctl search -i foo* -l 1 | jq
+{
+  "id": "1779364394",
+  "score": 1.0000,
+  "index": "foo2",
+  "source": {
+    "id": "1",
+    "message": "non-dead human looks curious at TargetOne"
+  }
+}
+```
+
+However, you might as well use internal filtering using jsonpaths:
+
+```console
+$ esctl search -i foo* -l 1 -p source.message
+non-dead human looks curious at TargetOne
+```
+
+To get more help about internal jsonpath filtering, run `esctl
+help-jsonpath`.
+
+A full text search looks like this:
+
+```console
+$ esctl search -i foo* thai | jq
+{
+  "id": "1779447242",
+  "score": 2.3842,
+  "index": "foo2",
+  "source": {
+    "message": "australian thai",
+    "title": "curry in a hurry"
+  }
+}
+```
+
+Instead of a costly full text you might as well specify the field to
+search within:
+
+```console
+$ esctl search -i foo* message=thai  | jq
+{
+  "id": "1779447242",
+  "score": 2.3842,
+  "index": "foo2",
+  "source": {
+    "message": "australian thai",
+    "title": "curry in a hurry"
+  }
+}
+```
+
+Of course you can search for multiple fields (or multiple terms in
+full text search). By default search terms are applied using logical
+AND, which you can change with the option `--or`.
+
+You can also change the sorting (`--sort-by`) and the time range
+(`--timerange`).
+
+To further narrow down search results you can add filters, which must
+match literally:
+
+```console
+$ esctl search -i foo* -F title=zeitbuchung message=pause | jq
+{
+  "id": "1779870750",
+  "score": 2.8426,
+  "index": "foo2",
+  "source": {
+    "message": "pause",
+    "time": "27.05.2026T10:33:45+0200",
+    "title": "zeitbuchung"
+  }
+}
+```
+
+To check which field mappings are available for an index:
+```console
+$ esctl index show foo2 
+INDEX-PROPERTY  VALUE                     
+name            foo2                      
+replicas        1                         
+shards          1                         
+created         2026-05-12 17:47:37       
+uuid            XmRtlh_JSreIzTB7jJNNJA    
+fields          id,message,time,title,user
+```
+
+Now, let's create a new index:
+
+```console
+$ esctl index create hyperdrive @timestamp:date message:keyword tag:text
+
+esctl index show hyperdrive 
+INDEX-PROPERTY  VALUE                 
+name            hyperdrive            
+replicas        1                     
+shards          1                     
+created         2026-06-24 10:16:23   
+uuid            gYfUj8TiR6aMB_BHmMYr3Q
+fields          @timestamp,message,tag
+```
+
+Once we have an index, we can insert documents into it (you'll need
+[gfn](https://codeberg.org/scip/gfn) for this):
+
+```console
+$ for name in $(gfn JapaneseNamesDiverse -n 20); do \
+     esctl doc add -i hyperdrive \
+     "{\"message\":\"$name\",\"tag\":\"loop\",\"@timestamp\":\"$(date
+     --iso-8601=second)\"}"; \
+     sleep 1; \
+  done

+2463257155346426021
+596556586001412147
+```
+
+Now, let's search them:
+
+```console
+$ esctl search -i hyperdrive -l 2 | jq
+{
+  "id": "2463257155346426021",
+  "score": 0.0000,
+  "index": "hyperdrive",
+  "source": {
+    "@timestamp": "2026-06-24T10:25:19+02:00",
+    "message": "inenen",
+    "tag": "loop"
+  }
+}
+{
+  "id": "596556586001412147",
+  "score": 0.0000,
+  "index": "hyperdrive",
+  "source": {
+    "@timestamp": "2026-06-24T10:25:20+02:00",
+    "message": "ominuhen",
+    "tag": "loop"
+  }
+}
+```
+
+There are also some uniq features which are not directly available via
+the ES API or GUI. Here's one example: say you have a number of
+indices with ILM policies each. At some day there were a surge in
+incoming data in some of them and you want to know, when the excess
+data will be rolled over to cold storage:
+
+```console
+$ esctl ilm forecast sh -f warm -w 3d 
+1.1 TB bytes of data in warm phase will be rolled within 72h0m0s to the next phase
+```
+
+You may also look at a detailed ilm forecast list:
+
+```console
+$ esctl ilm forecast ls -f warm -w 3d
+INDEX                           CURRENT-SIZE  CURRENT-AGE  VIRTUAL-AGE  MIN-AGE  MIN-SIZE  CURRENT-PHASE  NEXT-PHASE
+foobar-n1-p01-elastic-000126    12 GB         2d:8h:12m    3d:5h:16m    7d       25 GB     hot            warm

+foobar-n1-q01-misc-000072       18 GB         6d:15h:21m   4d:21h:36m   7d       25 GB     hot            warm      
+delaware-f1-p01-kafka-000023    1.3 MB        15h:12m      0s           7d       25 GB     hot            warm      
+delaware-f1-p01-misc-000024     17 GB         6d:16h:1m    4d:16h:33m   7d       25 GB     hot            warm      
+delaware-f1-q01-kafka-000023    1.5 MB        15h:12m      0s           7d       25 GB     hot            warm      
+delaware-f1-q01-misc-000024     16 GB         6d:15h:31m   4d:13h:52m   7d       25 GB     hot            warm      
+delaware-n1-p01-elastic-000417  16 GB         12h:42m      4d:10h:31m   7d       25 GB     hot            warm 
+```
+So you can see, which index will be rolled over when. Note the
+**VIRTUAL-AGE** field however: it is calculated from the current
+storage usage of the index in relation to rollover max shard size. So
+you can see, when an index will be rolled over either because it aged
+out or because its storage exceeded the limit.
+

+
+Please note, that `esctl` is still in its early stages and things are
+changing heavily every now and then. New commands are being added
+constantly as well.
