+## How to migrate from Gogs/GitHub/etc. to Gitea
+To migrate from Gogs to Gitea:
+
+* [Gogs version 0.9.146 or less]({{< relref "doc/upgrade/from-gogs.en-us.md" >}})
+* [Gogs version 0.11.46.0418](https://github.com/go-gitea/gitea/issues/4286)
+
+To migrate from GitHub to Gitea, you can use Gitea's [Migrator tool](https://gitea.com/gitea/migrator)
+
+To migrate from Gitlab to Gitea, you can use this non-affiliated tool:  
+https://github.com/loganinak/MigrateGitlabToGogs
+
+## Where does Gitea store "x" file
+* WorkPath
+  * Environment variable `GITEA_WORK_DIR`
+  * Else binary location
+* AppDataPath (default for database, indexers, etc.)
+  * `APP_DATA_PATH` from `app.ini`
+  * Else `%(WorkPath)/data`
+* CustomPath (custom templates)
+  * Environment variable `GITEA_CUSTOM`
+  * Else `%(WorkPath)/custom`
+* HomeDir
+  * Unix: Environment variable `HOME`
+  * Windows: Environment variable `USERPROFILE`, else environment variables `HOMEDRIVE`+`HOMEPATH`
+* RepoRootPath
+  * `ROOT` in `app.ini`
+  * Else `%(HomeDir)/gitea-repositories`
+* INI (config file)
+  * `-c` flag
+  * Else `%(CustomPath)/conf/app.ini`
+* SQLite Database 
+  * `PATH` in `database` section of `app.ini`
+  * Else `%(AppDataPath)/gitea.db`
+
+## Not seeing a clone URL or the clone URL being incorrect
+There are a few places that could make this show incorrectly.
+
+1. If using a reverse proxy, make sure you have followed the correction directions in the [reverse proxy guide]({{< relref "doc/usage/reverse-proxies.en-us.md" >}})
+2. Make sure you have correctly set `ROOT_URL` in the `server` section of your `app.ini`
+
+If certain clone options aren't showing up (HTTP/S or SSH), the following options can be checked in your `app.ini`
+
+`DISABLE_HTTP_GIT`: if set to true, there will be no HTTP/HTTPS link  
+`DISABLE_SSH`: if set to true, there will be no SSH link  
+`SSH_EXPOSE_ANONYMOUS`: if set to false, SSH links will be hidden for anonymous users  
+
+
+## Custom Templates not loading or working incorrectly
+Gitea's custom templates must be added to the correct location or Gitea will not find and use them.  
+The correct path for the template(s) will be relative to the `CustomPath`
+
+1. To find `CustomPath`, look for Custom File Root Path in Site Administration -> Configuration 
+  * If that doesn't exist, you can try `echo $GITEA_CUSTOM`
+2. If you are still unable to find a path, the default can be [calculated above](#where-does-gitea-store-x-file)
+3. Once you have figured out the correct custom path, you can refer to the [customizing Gitea]({{< relref "doc/advanced/customizing-gitea.en-us.md" >}}) page to add your template to the correct location.
+
+## Active user vs login prohibited user
+In Gitea, an "active" user refers to a user that has activated their account via email.  
+A "login prohibited" user is a user that is not allowed to log in to Gitea anymore
+
+## Setting up logging 
+* [Official Docs]({{< relref "doc/advanced/logging-documentation.en-us.md" >}})
+
+## What is Swagger?
+[Swagger](https://swagger.io/) is what Gitea uses for its API.  
+All Gitea instances have the built-in API, though it can be disabled by setting `ENABLE_SWAGGER` to `false` in the `api` section of your `app.ini`  
+For more information, refer to Gitea's [API docs]({{< relref "doc/advanced/api-usage.en-us.md" >}})
+
+[Swagger Example](https://try.gitea.io/api/swagger)
+
+## Adjusting your server for public/private use
+
+### Preventing spammers
+There are multiple things you can combine to prevent spammers.  
+
+1. By only whitelisting certain domains with OpenID (see below)
+2. Setting `ENABLE_CAPTCHA` to `true` in your `app.ini` and properly configuring `RECAPTCHA_SECRET` and `RECAPTCHA_SITEKEY`
+3. Settings `DISABLE_REGISTRATION` to `true` and creating new users via the [CLI]({{< relref "doc/usage/command-line.en-us.md" >}}), [API]({{< relref "doc/advanced/api-usage.en-us.md" >}}), or Gitea's Admin UI  
+
+### Only allow/block certain email domains
+If using OpenID, you can configure `WHITELISTED_URIS` or `BLACKLISTED_URIS` in your `app.ini`  
+**NOTE:** whitelisted takes precedence, so if it is non-blank then blacklisted is ignored
+
+### Issue only users
+The current way to achieve this is to create/modify a user with a max repo creation limit of 0.
+
+### Enable Fail2ban
+
+Use [Fail2Ban]({{ relref "doc/usage/fail2ban-setup.md" >}}) to monitor and stop automated login attempts or other malicious behavior based on log patterns
+
+## How to add/use custom themes
+Gitea supports two official themes right now, `gitea` and `arc-green` (`light` and `dark` respectively)  
+To add your own theme, currently the only way is to provide a complete theme (not just color overrides)  
+
+As an example, let's say our theme is `arc-blue` (this is a real theme, and can be found [in this issue](https://github.com/go-gitea/gitea/issues/6011))  
+Name the `.css` file `theme-arc-blue.css` and add it to your custom folder in `custom/pulic/css`  
+Allow users to use it by adding `arc-blue` to the list of `THEMES` in your `app.ini`
+
+## SSHD vs built-in SSH
+SSHD is the built-in SSH server on most Unix systems.  
+Gitea also provides its own SSH server, for usage when SSHD is not available.
+
+## Gitea is running slow
+The most common culprit for this is loading federated avatars.  
+This can be turned off by setting `ENABLE_FEDERATED_AVATAR` to `false` in your `app.ini`  
+Another option that may need to be changed is setting `DISABLE_GRAVATAR` to `true` in your `app.ini`
+
+## Can't create repositories/files
+Make sure that Gitea has sufficient permissions to write to its home directory and data directory.  
+See [AppDataPath and RepoRootPath](#where-does-gitea-store-x-file)
+
+**Note for Arch users:** At the time of writing this, there is an issue with the Arch package's systemd file including this line:
+`ReadWritePaths=/etc/gitea/app.ini`  
+Which makes all other paths non-writeable to Gitea.
+
+## Translation is incorrect/how to add more translations
+Our translations are currently crowd-sourced on our [Crowdin project](https://crowdin.com/project/gitea)  
+Whether you want to change a translation or add a new one, it will need to be there as all translations are overwritten in our CI via the Crowdin integration.
+
+## Hooks aren't running
+If Gitea is not running hooks, a common cause is incorrect setup of SSH keys.  
+See [SSH Issues](#ssh-issues) for more information.  
+
+You can also try logging into the administration panel and running the `Resynchronize pre-receive, update and post-receive hooks of all repositories.` option.
+
+## SSH issues
+If you cannot reach repositories over `ssh`, but `https` works fine, consider looking into the following.
+
+First, make sure you can access Gitea via SSH.  
+`ssh [email protected]`  
+
+If the connection is successful, you should receive an error message like the following:
+```
+Hi there, You've successfully authenticated, but Gitea does not provide shell access.
+If this is unexpected, please log in with password and setup Gitea under another user.
+```
+
+If you do not get the above message but still connect, it means your SSH key is **not** being managed by Gitea. This means hooks won't run, among other potential problems.
+
+If you cannot connect at all, your SSH key may not be configured correctly locally. 
+This is specific to SSH and not Gitea, so will not be covered here. 
+
+### SSH Common Errors
+
+```
+Permission denied (publickey).
+fatal: Could not read from remote repository.
+```
+
+This error signifies that the server rejected a log in attempt, check the
+following things:
+
+* On the client:
+  * Ensure the public and private ssh keys are added to the correct Gitea user.
+  * Make sure there are no issues in the remote url. In particular, ensure the name of the
+    git user (before the `@`) is spelled correctly.
+  * Ensure public and private ssh keys are correct on client machine.
+* On the server:
+  * Make sure the repository exists and is correctly named.
+  * Check the permissions of the `.ssh` directory in the system user's home directory.
+  * Verify that the correct public keys are added to `.ssh/authorized_keys`.  
+    Try to run `Rewrite '.ssh/authorized_keys' file (for Gitea SSH keys)` on the
+    Gitea admin panel.
+  * Read Gitea logs.
+  * Read /var/log/auth (or similar).
+  * Check permissions of repositories.
+
+The following is an example of a missing public SSH key where authentication
+succeeded, but some other setting is preventing SSH from reaching the correct
+repository.
+
+```
+fatal: Could not read from remote repository.
+
+Please make sure you have the correct access rights
+and the repository exists.
+```
+
+In this case, look into the following settings:
+
+* On the server:
+  * Make sure that the `git` system user has a usable shell set
+    * Verify this with `getent passwd git | cut -d: -f7`
+    * `usermod` or `chsh` can be used to modify this.
+  * Ensure that the `gitea serv` command in `.ssh/authorized_keys` uses the
+    correct configuration file.
+
+## Missing releases after migrating repository with tags
+
+To migrate an repository *with* all tags, you need to do two things:
+
+* Push tags to the repository:
+```
+ git push --tags
+ ```
+
+ * (Re-)sync tags of all repositories within Gitea:
+ ```
+ gitea admin repo-sync-releases
+ ```
+
+## LFS Issues
+
+For issues concerning LFS data upload
+
+```
+batch response: Authentication required: Authorization error: <GITEA_LFS_URL>/info/lfs/objects/batch                                                                                                              
+Check that you have proper access to the repository
+error: failed to push some refs to '<GIT_REPO_URL>'
+```
+Check the value of `LFS_HTTP_AUTH_EXPIRY` in your `app.ini` file.  
+By default, your LFS token will expire after 20 minutes. If you have a slow connection or a large file (or both), it may not finish uploading within the time limit. 
+
+You may want to set this value to `60m` or `120m`.
