**Installation Guide**

1. First, log into [Changyan](http://changyan.kuaizhan.com). Get the comment HTML code by following
   [this article](http://changyan.kuaizhan.com/static/help/index.html).

2. Copy the value of `appid` and `conf` to the corresponding settings in the theme configurations.
   For example, the following HTML code

    {% codeblock "Changyan Installation Code" lang:html >folded %}
    <!--PC版-->
    <div id="SOHUCS" sid="..."></div>
    <script charset="utf-8" type="text/javascript" src="https://cy-cdn.kuaizhan.com/upload/changyan.js" ></script>

    window.changyan.api.config({
        appid: '????appid????',
        conf: 'prod_xxxxxxxxxxxxxxxxxxxxxxx'
    });
    </script>
    {% endcodeblock %}
    
    maps to the following theme configuration:

    {% codeblock themes/icarus/_config.yml lang:yaml %}
    comment:
        type: changyan
        app_id: ????appid????
        conf: prod_xxxxxxxxxxxxxxxxxxxxxxx
    {% endcodeblock %}


## Disqus

<div>
<strong>Installation Guide</strong><a class="tag is-success ml-2" href="{% post_path demo/comment/Disqus %}">Preview</a>
</div>

1. First, log into [Disqus](https://disqus.com/). Click the "GET STARTED" button on the 
   front page or visit [here](https://disqus.com/profile/signup/intent/) and click "I want to install Disqus 
   on my site" to create a new Disqus comment service.

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqus-get-started.png 360 '"Get Started - Disqus" "Get Started - Disqus"' %}
   <br>

2. On the create new site page, fill in the "Website Name" and "Category", then click the "Create Site" button.

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqus-create-site.png 360 '"Create Site - Disqus" "Create Site - Disqus"' %}
   <br>

3. Select a subscription plan if you want to.
   You can also skip this by clicking "Install Disqus" on the left.

4. Next, choose the platform where Disqus is to be installed.
   Select the "I don't see my platform listed, install manually with Universal Code" on the bottom of the page.

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqus-select-platform.png 360 '"Select Platform - Disqus" "Select Platform - Disqus"' %}
   <br>

5. Click the "Configuration" button on the bottom of the page to skip the "Universal Code install instructions".

6. Make customizations to your Disqus service on the "Configure Disqus" page.
   Then, click the "Complete Setup" and "Dismiss Setup" buttons to finish the setup.

7. Next, click the "Edit Settings" button on the top right corner of the comment service home page.

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqus-service-homepage.png 360 '"Comment Service Homepage - Disqus" "Comment Service Homepage - Disqus"' %}
   <br>

8. Find the value of "Shortname" on the "Configure Disqus for Your Site" page, and copy it to the comment 
   settings in the theme configurations.
   For example, the "Shortname" in the following screenshot is `my-hexo-blog-1`:

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqus-get-shortname.png 360 '"Configure Disqus - Disqus" "Configure Disqus - Disqus"' %}
   <br>

   which maps to the following theme configuration:

    {% codeblock themes/icarus/_config.yml lang:yaml %}
    comment:
        type: disqus
        shortname: my-hexo-blog-1
    {% endcodeblock %}

9. (Optional) You can add `disqusId` in the front-matter of the post as the unique Disqus ID.
   Thereby, you can change the location of the post in the future without losing all your comments:

    {% codeblock source/_post/some-post.md lang:markdown %}
    title: My first post
    date: 2015-01-01 00:00:01
    disqusId: some-disqus-id
    ---
    # Hello world
    {% endcodeblock %}


##  DisqusJS

DisqusJS is an alternative for Disqus in areas where Disqus is restricted.
You can refer to [https://github.com/SukkaW/DisqusJS](https://github.com/SukkaW/DisqusJS)
for the detailed configuration process of DisqusJS.

<div>
<strong>Installation Guide</strong><a class="tag is-success ml-2" href="{% post_path demo/comment/DisqusJS %}">Preview</a>
</div>

1. Log into Disqus and visit [here](https://disqus.com/api/applications/).
   Click the "Register new application" button or "registering an application" to create a new Disqus application.

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqusjs-api-applications.png 360 '"Applications - Disqus" "Applications - Disqus"' %}
   <br>

2. Fill in the "Label", "Description", and "Website" on the next page.
   Then, click "Register my application".

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqusjs-register-application.png 360 '"Register Application - Disqus" "Register Application - Disqus"' %}
   <br>

3. After creating the application, go to the "Settings" tab of the application, fill in the domain name 
   of your Hexo site, e.g., ppoffice.github.io, in the "Domains" field.
   Then, click the "Save Changes" button on the bottom of the page.

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqusjs-application-settings.png 360 '"Application Settings - Disqus" "Application Settings - Disqus"' %}
   <br>

4. Click the "Details" link on the current page to go to the home page of the current application.
   Copy the "API Key" in the "OAuth Settings" section to the corresponding setting in the theme
   configurations.

   For example, the "API Key" in the following screenshot:

   {% img "box px-0 py-0 ml-auto mr-auto" /gallery/screenshots/disqusjs-api-key.png 360 '"Application Details - Disqus" "Application Details - Disqus"' %}
   <br>
   
   maps to the following theme configuration:

    {% codeblock themes/icarus/_config.yml lang:yaml %}
    comment:
        type: disqusjs
        shortname: my-hexo-blog-1
        api_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
        api: https://disqus.skk.moe/disqus/     # Optional
        admin: ppoffice                         # Optional

        nesting: 4                              # Optional
    {% endcodeblock %}

## Gitment

<article class="message message-immersive is-danger">
<div class="message-body">
<i class="fas fa-exclamation-triangle mr-2"></i>The maintenance of Gitment seems to be discontinued.

</div>
</article>

2. Copy the values of "Client ID" and "Client Secret" to the corresponding settings in the theme configurations.

   Here is an example of the Gitment configuration:

    {% codeblock themes/icarus/_config.yml lang:yaml %}
    comment:
        type: gitment
        owner: you_github_name
        repo: Some-of-Your-GitHub-Repo

   [hexo-component-inferno](https://github.com/ppoffice/hexo-component-inferno/blob/0.2.1/src/schema/comment/gitment.json).


## Isso

Isso is a valid choice if you wish to set up a self-hosted social comment system
instead of relying on third-party ones.
However, unlike the other services, Isso requires a web host for running the Isso server.

**Installation Guide**

1. Follow the [Isso documentation](https://posativ.org/isso/docs/install/) to install and run the Isso server.

2. Fill in the HTTP URL of Isso server to the corresponding setting in the theme configurations.
   For example, if your service URL is `https://posativ.org/isso/api/`, you will have the following 
   comment configuration:

    {% codeblock themes/icarus/_config.yml lang:yaml %}
    comment:
        type: isso
        url: posativ.org/isso/api
    {% endcodeblock %}
