+## Commands
+
+### Simple use
+<sub><sup>[↑ back to top](#meme-otron-guide)</sup></sub>
+
+You can generate memes by using the following arguments:
+
+```
+[meme id] "text1" "text2" ...
+```
+
+Depending of the number of `"text"` arguments, several behavior occurs:
+* **None**: you get the template that gives you the locations of texts. (see below)
+* **Less than the template's**: the remaining texts are blank on the output
+* **More than the template's**: the extra arguments are ignored
+
+> Notes
+> * You don't have to use all texts shown on the templates
+> * You can use an empty text argument ( `""` ) to skip a text and keep it blank
+
+See [Examples](#examples) to get an idea of how to use it.
+
+### Advanced use
+<sub><sup>[↑ back to top](#meme-otron-guide)</sup></sub>
+
+Since version 1.3, Meme-Otron allows you to "pipe" parts in order to compose more advanced memes. The syntax is as follows:
+
+```
+[part1] - [part2] - ...
+```
+
+Each `part` can be one of the following:
+
+* A template: as described in [Simple use](#simple-use)
+* Texts: ```text "text 1" "text 2" ...```
+  * Black Arial texts on white background
+  * Each text is it's own paragraph
+* Images: ```image <URL>```
+  * Takes an image from input or an URL (optional)
+  * Input depends on the system:
+    * the Discord bot takes the attachment
+    * the CLI takes stdin or `--input` argument.
+
+> Notes
+> * Input of `image` is always the same, don't expect multiple instances of `image` to get different results if you don't indicate an URL
+
+See [Examples](#examples) to get an idea of how to use it.
+
+### Discord features
+<sub><sup>[↑ back to top](#meme-otron-guide)</sup></sub>
+
+Tag the bot and use the above syntax to get started. In addition, you can use the following commands:
+
+* Use `help` to get a simple help message
+* Use `list` to get a list of all meme ids
+* Use `delete` to delete the last message sent by the bot (directed to you)
+
+To get the template info, just send the meme id without texts.
+
+> Tip : You can use `\\n` in your texts to add a line break 
+
+Enjoy the full experience of this bot by using direct messages to keep your server free of spam.
+
+### CLI features
+<sub><sup>[↑ back to top](#meme-otron-guide)</sup></sub>
+
+In this project directory, you can simply call:
+```
+python -m meme_otron [meme id] "text1" "text2" ... > output.jpg
+```
+Without pipe redirection with `-o [output]`:
+```
+python -m meme_otron -o output.png [meme id] "text1" "text2" ...
+```
+
+You can even pipe input images like this:
+```
+python -m meme_otron [arguments] < input.jpg > output.jpg
+```
+
+Available arguments:
+* `--help` / `-h`
+  * Show a simple guide
+* `--output [file]` / `-o [file]`
+  * Output file, you are free to choose the format
+* `--input [file]` / `-i [file]`
+  * Input file used for `image`
+* `-nw` / `--no-watermark`
+  * Removes the watermark
+* `-d` / `--debug`
+  * Add more info to output like a box show the texts boundaries
+* `-v` / `--verbose`
+  * Add more logging
+
+

+
+Since version 1.3, Meme-Otron allows you to "pipe" parts in order to compose more advanced memes. The syntax is as follows:
+
+```
+[part1] - [part2] - ...
+```
+
+Each `part` can be one of the following:
+
+* A template: as described in [Simple use](#simple-use)
+* Texts: ```text "text 1" "text 2" ...```
+  * Black Arial texts on white background
+  * Each text is it's own paragraph
+* Images: ```image <URL>```
+  * Takes an image from input or an URL (optional)
+  * Input depends on the system:
+    * the Discord bot takes the attachment
+    * the CLI takes stdin or `--input` argument.
+
+> Notes
+> * Input of `image` is always the same, don't expect multiple instances of `image` to get different results if you don't indicate an URL
+
+See [Examples](#examples) to get an idea of how to use it.
