Proper help text & new README structure (#311)

add cli.AppHelpTemplate for customization customize tea help view tea --version : improve parseability Rework README to include tea help output It's an antipattern to have different help texts aimed at the same users. So now that we have a good cli help text, lets use it here. This eases maintenance, and at the same time gives an honest impression on what we have to offer, while also encouraging to improve the internal help text in the future. I feel a bit sad for the GIF, but it was becoming outdated anyway.. group commands by category add new demo gif shows the (probably) most useful workflow readme improvement Merge branch 'master' into improve-app-help code review Merge branch 'master' into improve-app-help restructure installation section Co-authored-by: Norwin Roosen <git@nroo.de> Reviewed-on: https://gitea.com/gitea/tea/pulls/311 Reviewed-by: Lunny Xiao <xiaolunwen@gmail.com> Reviewed-by: khmarbaise <khmarbaise@noreply.gitea.io> Co-Authored-By: Norwin <noerw@noreply.gitea.io> Co-Committed-By: Norwin <noerw@noreply.gitea.io>

-Distribution packages exist for: **alpinelinux ([tea](https://pkgs.alpinelinux.org/packages?name=tea&branch=edge))** and **archlinux ([gitea-tea](https://aur.archlinux.org/packages/gitea-tea))**
+- [Compare features with other git forge CLIs](./FEATURE-COMPARISON.md)
+- tea uses [code.gitea.io/sdk](https://code.gitea.io/sdk) and interacts with the Gitea API.

+## Installation

-Shell completion can be added via `tea autocomplete --install`.
+There are different ways to get `tea`:

-## Usage
+1. Install via your system package manager:
+    - macOS via `brew` (gitea-maintained):
+      ```sh
+      brew tap gitea/tap https://gitea.com/gitea/homebrew-gitea
+      brew install tea
+      ```
+    - arch linux ([gitea-tea](https://aur.archlinux.org/packages/gitea-tea), thirdparty)
+    - alpine linux ([tea](https://pkgs.alpinelinux.org/packages?name=tea&branch=edge), thirdparty)

-First of all, you have to create a token on your `personal settings -> application` page of your gitea instance.
-Use this token to login with `tea`:
+2. Use the prebuilt binaries from [dl.gitea.io](https://dl.gitea.io/tea/)

-```sh
-tea login add --name=try --url=https://try.gitea.io --token=xxxxxx
-```
-
-Now you can use the following `tea` subcommands.
-Detailed usage information is available via `tea <command> --help`.
-
-```none
-login            Log in to a Gitea server
-logout           Log out from a Gitea server
-issues           List, create and update issues
-pulls            List, create, checkout and clean pull requests
-releases         List, create, update and delete releases
-repos            Operate with repositories
-labels           Manage issue labels
-times            Operate on tracked times of a repositorys issues and pulls
-open             Open something of the repository on web browser
-notifications    Show notifications
-milestones       List and create milestones
-organizations    List, create, delete organizations
-help, h          Shows a list of commands or help for one command
-```
+3. Install from source (go 1.13 or newer is required):
+    ```sh
+    go get code.gitea.io/tea
+    go install code.gitea.io/tea
+    ```

-To fetch issues from different repos, use the `--remote` flag (when inside a gitea repository directory) or `--login` & `--repo` flags.
